Outpatient ACL reconstruction using intraoperative local analgesia and oral postoperative pain medication

Thirty-five consecutive anterior cruciate ligament (ACL) reconstructions were performed in an ambulatory surgical unit using a bone-patellar tendon-bone autograft. Patients were evaluated postoperatively to determine the amount of pain medication used, the readmission rate, postoperative complications, and cost. Outpatient ACL reconstruction led to a savings of $4700 compared with the cost of performing the same procedure in a hospital operating room with an overnight admission. This study demonstrates that outpatient ACL reconstruction, using local analgesia intraoperatively and oral narcotic pain medication postoperatively, is a safe and cost-effective procedure with minimal to no morbidity.     

Ketorolac. A reappraisal of its pharmacodynamic and pharmacokinetic properties and therapeutic use in pain management

Ketorolac is a nonsteroidal anti-inflammatory drug (NSAID) with strong analgesic activity. The analgesic efficacy of ketorolac has been extensively evaluated in the postoperative setting, in both hospital inpatients and outpatients, and in patients with various other acute pain states. After major abdominal, orthopaedic or gynaecological surgery or ambulatory laparoscopic or gynaecological procedures, ketorolac provides relief from mild to severe pain in the majority of patients and has similar analgesic efficacy to that of standard dosages of morphine and pethidine (meperidine) as well as less frequently used opioids and other NSAIDs. The analgesic effect of ketorolac may be slightly delayed but often persists for longer than that of opioids. Combined therapy with ketorolac and an opioid results in a 25 to 50% reduction in opioid requirements, and in some patients this is accompanied by a concomitant decrease in opioid-induced adverse events, more rapid return to normal gastrointestinal function and shorter stay in hospital. In children undergoing myringotomy, hernia repair, tonsillectomy, or other surgery associated with mild to moderate pain, ketorolac provides comparable analgesia to morphine, pethidine or paracetamol (acetaminophen). In the emergency department, ketorolac attenuates moderate to severe pain in patients with renal colic, migraine headache, musculoskeletal pain or sickle cell crisis and is usually as effective as frequently used opioids, such as morphine and pethidine, and other NSAIDs and analgesics. Subcutaneous administration of ketorolac reduces pain in patients with cancer and seems particularly beneficial in pain resulting from bone metastases. The acquisition cost of ketorolac is greater than that of morphine or pethidine; however, in a small number of studies, the higher cost of ketorolac was offset when treatment with ketorolac resulted in a reduced hospital stay compared with alternative opioid therapy. The tolerability profile of ketorolac parallels that of other NSAIDs; most clinically important adverse events affect the gastrointestinal tract and/or renal or haematological function. The incidence of serious or fatal adverse events reported with ketorolac has decreased since revision of dosage guidelines. Results from a large retrospective postmarketing surveillance study in more than 20,000 patients demonstrated that the overall risk of gastrointestinal or operative site bleeding related to parenteral ketorolac therapy was only slightly higher than with opioids. However, the risk increased markedly when high dosages were used for more than 5 days, especially in the elderly. Acute renal failure may occur after treatment with ketorolac but is usually reversible on drug discontinuation. In common with other NSAIDs, ketorolac has also been implicated in allergic or hypersensitivity reactions. In summary, ketorolac is a strong analgesic with a tolerability profile which resembles that of other NSAIDs. When used in accordance with current dosage guidelines, this drug provides a useful alternative, or adjuvant, to opioids in patients with moderate to severe pain.     

Restricted expression of Fc gammaRIII (CD16) in synovium and dermis: implications for tissue targeting in rheumatoid arthritis (RA)

The authors conducted a prospective randomised double-blind comparison of patient-controlled analgesia (PCA), with a combination of morphine and ketorolac versus morphine alone and ketorolac alone in the management of postoperative pain after orthopaedic surgery. Forty-two patients were randomly assigned to three groups. Group 1 was given 1 mg/ml morphine, group 2 was given 3 mg/ml ketorolac and group 3 half-doses of each. After a loading dose of 0.07 ml/kg, PCA was started at an initial setting of 1 ml per demand, with a 10-min lock-out interval and no background infusion. Pain was measured at rest and during movements for 48 h. The combination of morphine and ketorolac was more effective than morphine or ketorolac alone in relieving rest pain throughout the study. The combination was also more effective during movement than either drug alone, but only for the first 24 h. The consumption of morphine and ketorolac was significantly lower when the two drugs were administered together. The incidence of urinary retention was highest in the group given morphine alone. The combination of half-doses of morphine and ketorolac is more effective in controlling postoperative pain than either drug alone. This combination also reduces analgesic consumption and morphine-related adverse events.     

ECG anomalies and axis deviations in heart transplant recipients: MRI studies]

Side effects of morphine are common when given in titrated doses to control severe pain in advanced cancer. We report a case series of acutely ill cancer patients suffering from pain, complications of advanced disease, and opioid side effects. They were treated with intravenous (i.v.) ketorolac along with i.v. morphine using repeated dosing. Excellent pain relief with improvement in the opioid bowel syndrome was achieved. We found it possible to switch from IV ketorolac to oral ketorolac along with oral morphine for long-term pain control. Ketorolac can be well tolerated in high-dose, long-term use even in this frail patient population. An algorithm is presented for the suggested use of ketorolac as a morphine sparing agent. Potential methods for studying ketorolac further in this role are discussed.     

Differences between heterosexual, bisexual, and lesbian women in recalled childhood experiences

In an editorial, Kapur [4] described perioperative nausea and vomiting as the big "little problem following ambulatory surgery." In contrast to the attitudes of some physicians, patients put a high value on freedom from nausea and emesis in the postoperative period and are willing to accept some pain and drowsiness as the cost of controlling PONV [85]. Until recently, there had been little change in the incidence of postoperative emesis since the introduction of halothane into clinical practice in 1956. However, the introduction of the IV anesthetic agent propofol and of the NSAID ketorolac, plus abandonment of the policy of insisting that patients drink before discharge, appear to have contributed to a recent decline in the incidence of emesis. With the availability of new antiserotonin drugs, the incidence of recurrent (intractable) emesis could be further decreased, particularly if combination therapy is used. Further research into the mechanisms of this common postoperative complication may help in improving the management of emetic sequelae in the future. Improvements in antiemetic therapy could have a major impact for surgical patients, particularly those undergoing ambulatory surgery. Just as pain is no longer considered an unavoidable part of the postoperative experience, so should nausea and vomiting be considered an avoidable side effect.     

Frequency, intensity, development and repercussions of postoperative pain as a function of the type of surgery

Type of surgery is the most important factor conditioning intensity and duration of postoperative pain. Thoracic and spinal surgery are the most painful procedures. Abdominal, urologic and orthopedic surgery lead to severe postoperative pain. Duration of severe pain rarely exceeds 72 hours. Mobilization increases pain intensity after abdominal, thoracic and orthopaedic surgery. Pain could occur after daycase minor surgical procedures and is often underestimated. Postoperative complications related to pain are difficult to disclose because of the interposition of the direct effects of analgesic treatments. Respiratory and cardiovascular postoperative complications are unrelated to postoperative pain in healthy subjects. This could be different in high risk patients. The surgical procedure is the major determinant of metabolic and psychologic postoperative deterioration. Adequate pain relief allows postoperative rehabilitation and physiotherapy programmes after abdominal and orthopaedic surgery. This could be expected to reduce hospital stay and improve convalescence.     

Epidemiology of insect venom sensitivity in children and its correlation to clinical and atopic features

STUDY DESIGN: The influence of ketorolac on spinal fusion was studied in a retrospective review of 288 patients who underwent an instrumented spinal fusion. OBJECTIVE: To assess the effect of postoperative ketorolac administration on subsequent fusion rates. SUMMARY OF BACKGROUND DATA: Nonsteroidal anti-inflammatory drugs are widely used compounds, which are known to inhibit osteogenic activity and have been shown to decrease spinal fusion in an animal model. No previous studies have examined the influence of nonsteroidal anti-inflammatory drugs on spinal fusion in clinical practice. METHODS: The medical records of 288 patients who underwent instrumented spinal fusion from L4 to the sacrum between 1991 and 1993 were reviewed retrospectively. The 121 patients who received no nonsteroidal anti-inflammatory drugs were compared with the 167 patients who received ketorolac after surgery. The groups were demographically equivalent. RESULTS: Ketorolac had a significant adverse effect on fusion, with five nonunions in the nondrug group and 29 nonunions in the ketorolac group (P > 0.001). Ketorolac administration also significantly decreased the fusion rate for subgroups including men, women, smokers, and nonsmokers. The odds ratio demonstrated that nonunion was approximately five times more likely after ketorolac administration. Cigarette smoking also decreased the fusion rate (P > 0.01); smokers were 2.8 times more likely to develop nonunion. CONCLUSION: These data suggest that nonsteroidal anti-inflammatory drugs significantly inhibit spinal fusion at doses typically used for postoperative pain control. The authors recommend that these drugs be avoided in the early postoperative period.     

Effects of high doses of theophylline on memory acquisition

Although tourniquets are used commonly during anterior cruciate ligament (ACL) surgery, little data are available regarding their effects on postoperative function. This retrospective study evaluated 94 patients who had an arthroscopically assisted, autogenous bone-patellar ligament-bone ACL reconstruction between 1988 and 1991 at the San Diego Kaiser Hospital. A tourniquet was used in 48 patients (T+ group). No tourniquet was used in 46 patients (T- group). The surgical and postoperative protocols were identical for the two groups. There were no bleeding complications. There was no significant difference in anesthesia time between the two groups. This study has shown that ACL surgery can be performed expeditiously without a pneumatic tourniquet. Quadriceps strength recovery after surgery was less in the T+ group at 12 weeks after surgery, but there was no significant difference between the groups 52 weeks after surgery. Difference in thigh girth was greater in T+ group 6 and 12 weeks after surgery, but there was no significant difference between the groups 52 weeks after surgery.     

Ketorolac and propofol administration for prevention of nausea and vomiting in patients undergoing minor gynecologic surgery

This clinical review explores the efficacy of the nonsteroidal antiinflammatory agent, ketorolac tromethamine, added to an anesthetic regimen utilizing intravenous propofol. Both agents have been shown to reduce the incidence of nausea and vomiting postoperatively when administered to patients undergoing minor gynecologic surgery. Because the incidence of nausea and vomiting is significantly reduced when ketorolac is used in place of opioids to attenuate postoperative pain, it would appear to be an appropriate choice of agent to use following propofol anesthesia. The use of this combination of drugs may not only reduce the incidence of postoperative nausea and vomiting in patients undergoing minor gynecologic surgery, but could reduce the duration of hospitalization and enhance recovery from anesthesia.     

Evaluation of the safety and efficacy of ketorolac versus morphine by patient-controlled analgesia for postoperative pain

STUDY OBJECTIVE: To compare ketorolac tromethamine with morphine for pain management after major abdominal surgery. DESIGN: Double-blind, randomized study. SETTING: Hospital recovery room and postoperative surgical unit. PATIENTS: One hundred ninety-one patients with at least moderate pain after major abdominal surgery. INTERVENTIONS: Patients received ketorolac by patient-controlled analgesia (PCA) bolus alone (Ket B), ketorolac by bolus plus infusion (Ket I), or morphine by PCA bolus (morphine), with injectable morphine available for supplementation. MEASUREMENTS AND MAIN RESULTS: Levels of sedation, pain intensity, pain relief, and adverse events were recorded at baseline, at 2, 4, and 6 hours, and at termination. Supplemental morphine was required by 71% of Ket B patients, 67% of Ket I patients, and 38% of morphine patients (p < or = 0.001 for Ket B vs morphine). Although patients receiving ketorolac required more supplemental morphine than the morphine group (6.0 mg Ket I, 6.2 mg Ket B, 4.0 mg morphine), there was a large morphine-sparing effect in both ketorolac groups (total morphine 6.0 mg Ket I, 6.2 mg Ket B, 33.3 mg morphine). Overall pain relief scores were similar for morphine and Ket I groups, and were lower for Ket B than for morphine (p = 0.002). There were no differences among groups in numbers of patients with adverse events. CONCLUSION: Ketorolac may be effective when administered by PCA device, and has a clear morphine-sparing effect.     

Effect of starvation on organ blood flow in the senescent rat

Since the first true hernioplasty performed by Edoardo Bassini more than 100 years ago (1884) all surgical reconstruction techniques have shared a common defect i.e. tension on suture line. This is the first etiologic factor of recurrent hernia. On the contrary by the use of modern prosthetic materials (mesh and plug) it is now possible to marriage all hernia repairs without distorting normal body anatomy and avoid undesirable tensions. The technique proposed is simple, efficient, characterized by a rapid performing procedure, giving way to an excellent clinical outcome: postoperative pain relief permitting the patient to resume in a short time his normal physical activities. In this paper the authors present their experience in wall defects reconstruction by means of outpatient surgery and in general anesthesia in the period spanning from 1994 to 1996. Five different types of hernia mesh in hernioplasty procedures were evaluated and used.     

Does the preoperative administration of ketorolac improve postoperative analgesia

AIM OF THE STUDY: 1) To verify the usefulness of ketorolac administration (30 mg i.v.) before a surgical operation in terms of postoperative analgesia improvement; 2) To evaluate the impact of preoperative ketorolac administration on perioperative renal function and on intraoperative water balance; 3) to evaluate the presence of adverse effect due to preoperative NSAID use. DESIGN: Prospective randomized trial. SETTING: University surgical department. PATIENTS AND METHODS: Forty adult patients undergoing major abdominal surgery, randomized in 2 groups: in group 1 ketorolac (30 mg i.v.) was administered immediately after the induction and, for postoperative analgesia, ketorolac (30 mg i.v.) was administered beginning at the time of skin closure; in group 2 no ketorolac was administered before the operation and postoperative treatment was the same. Buprenorphine (0.3 mg i.m.) was administered in case of unsatisfactory analgesia. Fluids infused and diuresis were measured intraoperatively. One, 6 and 24 hours after the end of operation pain was evaluated using pain intensity score and VAS. The day after the operation serum creatinine and urea were measured. RESULTS: No statistically significant differences were found between groups regarding fluids infused, intraoperative diuresis, postoperative pain, adverse effects and number of bleeding episodes. More than 50% of patients, in either groups, required opioids administration. CONCLUSIONS: Ketorolac (30 mg i.v.) administration before a major abdominal operation does not improve postoperative analgesia nor determines significant alterations in renal function or increase in the frequency of abnormal bleedings. Opiate administration is necessary in more than 50% of the patients to achieve adequate analgesia.     

Understanding shoulder arthroplasty

This article discusses the vital role of the professional nurse when caring for patients who have shoulder replacement surgery. The indications for surgery, recent advances in the surgical procedure, postoperative management, and potential complications are reviewed.     

Immobilisation of levansucrase on calcium phosphate gel strongly increases its polymerase activity

The goal of podiatric surgery in the older patient should be pain management with the highest degree of functional restoration. Thorough preoperative analysis, meticulous surgical technique, and careful postoperative planning are necessary to ensure a favorable surgical result. Each planned procedure must coincide with the specific needs of the individual patient while conforming to the body's physical limitations. A complete medical examination with laboratory studies is indicated due to the elderly patient's inherent diminished physical status. When the patient is deemed a proper candidate for surgery, the medical team, family, and friends should be consulted regarding immediate and long-term postoperative care. Strict adherence to these principles is in the best interest of both the practitioner and the older patient.     

Proctological surgery in the one-day surgery regimen: the preliminary results with 232 patients

Simple anorectal surgery can be routinely employed on a one-day surgery (ODS) bases; however complications such as bleeding, urinary retention, and postoperative pain represent a limitation in this respect. In this paper we report preliminary results of our experience in surgery for haemorrhoids, anal fissures and fistulas, achieved in two years on 232 patients. Our protocol includes admission in the morning of the operation and preoperative evaluation by means of ECG, coagulation profile, assay of beta-HCG for female patients. The patients, prepared with a self-administered enema and perianal applications of prilocaine-lidocaine ointment, is taken in the operative room were a venous line is placed and an anaesthesiologist proceed to monitoring of ECG, blood pressure and oximetry. 211 patients were operated under locoregional anaesthesia performed by the surgeon by means of bilateral pudendal nerves blocking. Whereas the remaining underwent general or spinal anesthesia. With this approach we performed 106 haemorrhoidectomies, 96 sphincterotomies, 19 of which with posterior anoplasty and 30 fistulectomy or fistulotomy. 60 mg of ketorolac have been injected locally at the end of operation in order to improve postoperative pain control. Patients undergoing hemorrhoidectomy, anoplasty, fistulotomy or fistulectomy were discharged after 24 hours whereas those undergoing sphincterotomy went home the same day. We reported 4 early postoperative complications in the haemorrhoids group with an incidence of 1.7% (two bleedings, one urinary retention and one fever) treated conservatively. Postoperative pain resulted adequately controlled by a low dosage of NSAID (a mean of 3.7 doses of 30 mg ketorolac/patient). Our satisfactory results seem to suggest continuing the practice of one-day surgery in proctology.     

Regulation of melatonin synthesis in rainbow trout (Oncorhyncus mykiss) pineal organs: effects of calcium depletion and calcium channel drugs

In a double-blind, randomized trial, 40 patients undergoing open anterior cruciate ligament (ACL) reconstruction using a bone-patellar tendon-bone autograft were randomly allocated to two groups: group A (n = 20) received an intra-articular instillation of 20 mL bupivacaine (0.25%) and a local infiltration of 20 mL bupivacaine (0.5%) 15 minutes before surgery. Group B (n = 20) received an injection of saline solution in the same manner. Patient-controlled on-demand analgesia (PCA) with intravenous piritramid was used for postoperative pain control. A significant decrease in pain scores on a visual analog scale (VAS scale, 0 to 10) was found in the bupivacaine group (group A) at bedrest on the day of surgery only (pain score, 5.5 v 7.3 (scale, 0 to 10), P < .05). At all other times, no significant differences were found. The overall supplemental opioid requirements were not different between the study groups (63.9 v 62.6 mg piritramid/72 hours). A long-lasting, clinically relevant, pain-reducing effect with infiltration of bupivacaine before surgery could not be shown with this study.     

The intubating laryngeal mask. II: A preliminary clinical report of a new means of intubating the trachea

To determine the effect of anterior cruciate ligament (ACL) reconstruction on symptoms of pain and instability in patients with chronic ACL insufficiency who had previously undergone meniscectomy, we reviewed a series of 21 symptomatic, previously meniscectomized patients with chronic ACL deficiency (average age, 31 years). Arthroscopically assisted intra-articular ACL reconstruction using a middle, one-third patella-tendon autograft was performed in all cases. All patients had radiographic evidence of degenerative changes before ACL reconstruction. The average time from meniscectomy to ACL reconstruction was 6.6 years. Preoperative and postoperative range of motion, stability, and subjective evaluations were compared. Follow-up averaged 37.4 months (range, 24 to 67 months). Physical examination and postoperative KT-1000 side-to-side measurements revealed three patients (14%) with pathological ligament laxity. One patient had a 2+ Lachman, a 2+ pivot shift, and > 5 mm difference on KT-1000 maximum manual test, and two patients had a 1+ Lachman and a 1+ pivot shift. Range of motion measurements taken at follow-up were not significantly different from preoperative measurements (extension, P = .14; flexion, P = .46). Subjectively, all items on a panel of 15 visual analog scales were improved, but intensity of pain and instability were significantly improved after statistical analysis (P < .05). This review suggests that symptoms of pain and instability in patients with chronic ACL deficiency who have previously undergone meniscectomy can be improved by ACL reconstruction if objective stability is obtained.     

Effect of parental mental health status on adolescents'' dietary behaviors

Ketorolac is the only nonsteroidal anti-inflammatory drug (NSAID) in widespread clinical use that is available in an injectable form. Though similar to aspirin and ibuprofen, it is much more potent. In fact, it is potent enough to be useful for postsurgical pain either alone or in combination with other pain relief strategies. For many types of pain, ketorolac is comparable in potency with opioids though the mechanism by which it relieves pain is significantly different. Ketorolac has a much longer duration than morphine or meperidine but has a slower onset. Though we sometimes perceive NSAIDs as almost harmless, ketorolac is a potent drug and, like other potent drugs, has the potential to produce potent adverse effects including organ disfunction and allergic reaction. Risk factors for these adverse effects are well understood, allowing the clinician to plan the ketorolac use safely. Well planned patient selection and ketorolac administration can improve patient care by reducing opioid side effects and improving analgesia while speeding patient recovery and PACU discharge times.     

Analgesia after surgery of the shoulder

Postoperative pain after shoulder surgery is known to be intense and requires usually opioid administration. The recent use of regional anaesthesia for this type of surgery has contributed to the relief of acute postoperative pain occurring in the recovery room since the analgesic effects of block persist for several hours after surgery depending upon the selected drug. Moreover, the development of less invasive surgery (arthroscopy) and experience with regional blocks have permitted to perform minor shoulder surgery on an outpatient basis. For minor surgery, regional anaesthesia associated to a light sedation is sufficient. However, for more invasive surgery, regional anaesthesia should be associated to a light general anaesthesia as well as the insertion of a supraclavicular catheter for postoperative analgesia. A diaphragmatic paresis secondary to a blockade of the phrenic nerve is constant radiologically after interscalenic block but remains symptomless. However, in case of severe preoperative chronic respiratory insufficiency, decompensation may occur rapidly after performance of the interscalenic block.     

Effects of ketorolac on bone repair: A radiographic study in modeled demineralized bone matrix grafted rabbits

The treatment of instability of the multiply reoperated knee is a complex problem. The causes for failure are numerous and include repeated trauma, insufficient fixation and non-anatomic placement of the graft, inadequate replacement material, isolated anterior cruciate ligament (ACL) reconstruction in complex knee instability or the use of a ligament prosthesis. With every surgical procedure, however, the anatomical and technical conditions become worse. Problems like degenerative changes, joint stiffness and gait abnormalities occur and often become a more focal point than the instability itself. The purpose of this paper is to present the problems and the dilemma of instability of the multiply reoperated knee and the possible solutions. Between 1976 and 1996, a total of 1752 ACL reconstructions were carried out in Munich and Hannover. Of these, 228 (13%) were revision, mostly of failed ACL reconstructions performed elsewhere. Since 1989, we have chosen the severest cases from this group (more than three operations on the same knee) for this study. Seventeen patients were investigated who had undergone up to 25 operations. The mean number of operations was 7. All primary operations were performed in other hospitals. In 10 cases only the ACL reconstruction was performed as a final procedure, mostly in combination with other procedures like medial meniscus replacement, extra-articular stabilization or arthrolysis. In the other cases operations such as osteotomies, arthrodesis or amputation were necessary. The results present the main dilemma in instability of the multiply reoperated knee since they were not successful in all patients. Finally, 15 patients report still having instability, pain or swelling in isolation or in combination. Nine patients were satisfied with their subjective results. Even after the socalled definitive procedures, certain complications arose. The main goal in the treatment of instability of the multiply reoperated knee is to avoid a series of operations, hospitalization and history of illness. General revision surgery for the entire complaint is not the aim of the treatment. The specific problem of the patient should be extracted from the complex situation, and this should be solved with the most limited procedure possible only.
