Incidence of hematoma associated with ketorolac after TRAM flap breast reconstruction

Ketorolac is frequently used as an adjunct for postoperative pain relief, especially by anesthesiologists during the immediate postoperative period. It can be used alone as an analgesic but is more often used to potentiate the actions of narcotics such as morphine or meperidine in an attempt to reduce the total dose and side effects of those drugs. The manufacturer of ketorolac cautions against its use in patients who have a high risk of postoperative bleeding, for fear of increasing the risk of hematoma, but the risk in transverse rectus abdominis musculocutaneous (TRAM) flap patients has never been reported. In a study of 215 patients who had undergone TRAM flap breast reconstruction, it was determined that patients who received intravenous ketorolac (n = 65) as an adjunct to their treatment with morphine administered by use of a patient-controlled analgesia device required less morphine (mean cumulative dose, 1.39 mg/kg) than did patients who did not receive ketorolac (n = 150; mean cumulative dose, 1.75 mg/kg; p = 0.02). There was no increase in the incidence of hematoma in patients who were treated with ketorolac. The data presented in this study suggest that the use of intravenous ketorolac does reduce the need for narcotics administration in patients undergoing TRAM flap breast reconstruction, without significantly increasing the risk of hematoma.     

Cost effectiveness analysis of intravenous ketorolac and morphine for treating pain after limb injury: double blind randomised controlled trial

ObjectivesTo investigate the cost effectiveness of intravenous ketorolac compared with intravenous morphine in relieving pain after blunt limb injury in an accident and emergency department.DesignDouble blind, randomised, controlled study and cost consequences analysis.SettingEmergency department of a university hospital in the New Territories of Hong Kong.Participants148 adult patients with painful isolated limb injuries (limb injuries without other injuries).ResultsNo difference was found in the median time taken to achieve pain relief at rest between the group receiving ketorolac and the group receiving morphine, but with movement the median reduction in pain score in the ketorolac group was 1.09 per hour (95% confidence interval 1.05 to 2.02) compared with 0.87 (0.84 to 1.06) in the morphine group (P=0.003). The odds of experiencing adverse events was 144.2 (41.5 to 501.6) times more likely with morphine than with ketorolac. The median time from the initial delivery of analgesia to the participant leaving the department was 20 (4.0 to 39.0) minutes shorter in the ketorolac group than in the morphine group (P=0.02). The mean cost per person was $HK44 (£4; $5.6) in the ketorolac group and $HK229 in the morphine group (P<0.0001). The median score for patients'' satisfaction was 6.0 for ketorolac and 5.0 for morphine (P<0.0001).ConclusionIntravenous ketorolac is a more cost effective analgesic than intravenous morphine in the management of isolated limb injury in an emergency department in Hong Kong, and its use may be considered as the dominant strategy.     

Patient-controlled analgesia with ketorolac in pediatric surgery

Our aim was to quantify the analgesic efficiency of the patient-controlled analgesia technique (PCA), using ketorolac, in children aged 6-14 undergoing a surgical intervention. We carried out a double-blind test with two randomly selected groups: the PCA group comprising patients submitted to intravenous PCA, with "bolus on demand" and the Standard group, with conventional analgesia dispensed with ketorolac I.V. (0.5 mg/kg/6 hours). Evaluation of pain experienced was performed using the Hannallah behavioural scale and quantification of the summing of pain intensity. Analgesic efficiency was determined by the pain intensity difference (PID) score. Evaluation of pain experienced during hour 1 reveals a marked reduction with time for each group; no inter-group differences were found. At hour 6 there were neither intra-group nor inter-group differences. The accumulated pain score revealed a significant reduction in hour 6, with no differences between the two groups. Evaluation of the analgesic effect revealed no differences, either intra-group or intergroup, during the experimental period. The sum of the PIDs revealed significant differences in the standard group between the values for hours 1 and 6. Under the experimental conditions described, both techniques were equally effective for pain treatment, but the efficiency was higher for the PCA group.     

The effects of ketorolac and morphine on articular cartilage and synovium in the rabbit knee joint

Analgesics are commonly injected intra-articularly for analgesia after arthroscopic surgery, especially of knee joints. The aim of this study was to research the effects of ketorolac and morphine on articular cartilage and synovial membrane. This study used rabbit right and left hind knee joints. The treatments, saline, morphine, or ketorolac, were administered intra-articularly 24 h after injection, and 5 joints from animals in each drug group were chosen randomly to form Group I and subgroups of Group I. The same procedures were applied after 48 h and 10 days of injection to form Groups II and III, respectively, and subgroups of these groups. Knee joints were excised and a blinded observer evaluated the histopathology according to inflammation of the articular cartilage, inflammatory cell infiltration, hypertrophy, and hyperplasia of the synovial membrane. No histopathological changes were found in the control groups. In the ketorolac and morphine groups, there were varying degrees of synovial membrane inflammatory cell infiltration and minimal, mild, or moderate synovial membrane cell hyperplasia or hypertrophy. Except for the ketorolac group at 24 h, both ketorolac and morphine groups showed more histopathological changes than controls (p < 0.05). Morphine and ketorolac both cause mild histopathological changes in rabbit knee joints, morphine causing more than ketorolac, but both of the drugs can be used intra-articularly with safety.     

肺癌根治术后不同镇痛方式的临床效果比较

目的：观察和比较硬膜外自控镇痛（PCEA）和静脉自控镇痛（PCIA）用于肺癌根治术患者围术期的镇痛效果及其不良反应的发生情况。方法：选择择期全麻下行肺癌根治性切除术的患者1214例,ASAI～II级,依镇痛方式不同分为硬膜外自控镇痛组（PCEA组,n=1023）和静脉自控镇痛组（PCtA组,n=191）。观察围术期两组患者镇痛效果、不良反应及术后康复情况。结果：PCEA组术后2h静止状态下和术后6h、24h活动状态下VAS评分均明显低于PCIA组（P〈O．05）;术后48h的Ramsay评分明显低于PCIA组（P〈0．05）;术后住院时间明显短于PCIA组（P〈0．05）;肺部并发症的发生率、切口感染和术后谵妄、恶心呕吐的发生率均明显低于PCIA组（P〈0．01）。结论：PCEA和PCIA两种镇痛方式用于肺癌根治术患者围术期均可达到满意的临床镇痛效果,但PCEA的用药量更少,镇静作用轻,副反应少,并可以降低肺感染和切口感染的几率,缩短住院时间,更有利于肺癌根治术患者的镇痛和康复。

Patient-controlled and analgesia with ketorolac in pediatric surgery

Our aim was to quantify the analgesic efficiency of the patient-controlled analgesia technique (PCA), using ketorolac, in children aged 6–14 undergoing a surgical intervention.

Postoperative morphine requirements of free TRAM and DIEP flaps

In a review of the charts of 158 patients who had undergone breast reconstruction with free transverse rectus abdominis musculocutaneous (TRAM) or deep inferior epigastric perforator (DIEP) flaps and who were treated for postoperative pain with morphine administered by a patient-controlled analgesia pump, the total dose of morphine administered during hospitalization for the flap transfer was measured. Patients whose treatment was supplemented by other intravenous narcotics were excluded from the study. The mean amount of morphine per kilogram required by patients who had reconstruction with DIEP flaps (0.74 mg/kg, n = 26) was found to be significantly less than the amount required by patients who had reconstruction with TRAM flaps (1.65 mg/kg; n = 132; p < 0.001). DIEP flap patients also remained in the hospital less time (mean, 4.73 days) than did free TRAM flap patients (mean, 5.21 days; p = 0.026), but the difference was less than one full hospital day. It was concluded that the use of the DIEP flap does reduce the patient requirement for postoperative pain medication and therefore presumably reduces postoperative pain. It may also slightly shorten hospital stay.     

Analysis of preincisional and postincisional treatment with alpha2-adrenoreceptor agonist clonidine regarding analgesic consumption and hemodynamic stability in surgical patients

Preemptive analgesia aims to prevent the sensitization of central nervous system, hence the development of pathologic pain after tissular injury. The aim of the study was to assess the effect of preincisional clonidine treatment on analgesic consumption and hemodynamic stability compared to clonidine administered at the end of the operation and control group. Ninety-one patients undergoing elective colorectal surgery were randomly assigned to four groups: peroral clonidine before operation, epidural clonidine before operation, epidural clonidine at the end of operation, and epidural saline before operation as a control group. After the operation, patient-controlled analgesia with epidural morphine was instituted. Analgesic consumption, blood pressure and heart rate were obtained at 1, 2, 6 and 24 h postoperatively, and the cumulative consumption of analgesics was assessed at the end of the study period. Significant differences (p < 0.05) in postoperative systolic blood pressure, with highest hemodynamic stability was observed at 1 h and 6 h in the group of patients administered epidural clonidine before operation. In this group of patients we found significant reduction in analgesic consumption during the study period (p < 0.05), compared to other groups. The cumulative consumption of analgesics assessed at the end of the study period was significantly reduced (p < 0.05) in the group of patients administered epidural clonidine before operation (8.40 +/- 3.74, respectively) as compared with the peroral clonidine before operation (16.79 +/- 5.75, respectively), epidural clonidine at the end of the operation (11.11 +/- 4.24, respectively) and control group of patients (18.00 +/- 6.45, respectively). Preincisional administration of epidural clonidine was associated with a significantly lower analgesic use, lower cumulative analgesic consumption and greater hemodynamic stability, in comparison with other groups.

Peripheral regional analgesia with femoral catheter versus intravenous patient controlled analgesia after total knee arthroplasty: a prospective randomized study

The aim of this study is to compare the effects of femoral analgesia (FA) with 0.25% levobupivacain and intravenous patient controlled analgesia (PCA) with morphine on postoperative pain assessed by a visual-analog scale (VAS) score and their complications during the first 24 postoperative hours after the a total knee arthroplasty in a prospective randomized study. Secondary outcomes included: morphine use, patient satisfaction, complication of analgesia and duration of hospital stay. We analyzed 71 patients with an ASA score of II or III. The patients were randomized into two groups: group PCA (n = 36) was given the PCA pump, which contained morphine; and group FA (n = 35) was given first a bolus dose, then a continuous infusion 0.25% levobupivacain via a femoral catheter. The assessment of VAS was performed every 2 hours. There were no differences between the PCA and FA groups regarding demographic characteristics, operation duration, ASA score distribution, duration of hospital stay and satisfaction with analgesia (although there were more satisfied patients in the FA group). Significant differences were noted in the quantity of morphine used (higher values were in the PCA group; p < 0.001). More complications were recorded in PCA group (p < 0.001). The VAS score was lower in the FA group (p < 0.001). The highest difference occurred 4 hours after the operation, with the PCA group having significantly higher VAS score values compared to the FA group. Femoral analgesia leads to a stronger pain relief with less side effects, less morphine use and more patient satisfaction than intravenous PCA with morphine.     

The Effectiveness of Pregabalin for Post-Tonsillectomy Pain Control: A Randomized Controlled Trial

BackgroundAlthough various analgesics have been used, postoperative pain remains one of the most troublesome aspects of tonsillectomy for patients.ObjectiveThe aim of the present study was to evaluate the effectiveness of premedication using pregabalin compared with placebo (diazepam) on postoperative pain control in patients undergoing tonsillectomy.MethodsForty-eight adult patients were randomly divided into a control group and a pregabalin group. Preoperatively, patients in the control group received 4 mg diazepam orally as placebo, whereas those in the pregabalin group received 300 mg pregabalin orally. All participants were provided with patient-controlled analgesia using fentanyl for 24 hours after surgery. Postoperative pain treatment included acetaminophen 650 mg three times daily for 8 postoperative days. The primary outcome measure was the total amount of patient-controlled fentanyl consumption after tonsillectomy. Secondary outcome measures were the number of injections of ketorolac tromethamine (each 30 mg) requested by patients, pain scores, overall satisfaction scores, drowsiness, nausea, dizziness, headache, and vomiting after the surgery. P < 0.05 was considered statistically significant.ResultsThe total amount of fentanyl demanded decreased significantly in the pregabalin group (P < 0.001). There were no significant differences in the number of ketorolac tromethamine injections, pain scores, overall satisfaction scores, drowsiness, nausea, dizziness, headache, and vomiting between the two groups.ConclusionAdministration of 300 mg pregabalin prior to tonsillectomy decreases fentanyl consumption compared with that after 4 mg diazepam, without an increased incidence of adverse effects.
