The alpha-adrenergic agonists have been demonstrated to have synergistic effects with opioids and local anesthetics in animal research. The present study was performed to determine whether the addition of adrenaline improves the analgesic effects of an epidural infusion of a combination of fentanyl and bupivacaine after abdominal surgery. We studied 90 ASA 1 or 2 patients scheduled for abdominal surgery under epidural anaesthesia, with or without general anaesthesia. Patients were randomly divided into two groups to receive a postoperative epidural infusion of fentanyl 5 micrograms/ml in bupivacaine 0.2%, with or without adrenaline 5 micrograms/ml, at a rate of 2 ml/h for more than 48 hours. Postoperative pain relief was assessed using visual analog scales (VAS), both at rest and during coughing, at 2, 24, and 48 hours after surgery. The number of rescue analgesics and side-effects such as nausea, vomiting, pruritus, respiratory depression, headache, muscle weakness, and hypotension were recorded. Patients who received adrenaline (n = 40) reported significantly lower mean VAS scores than those who received no adrenaline (n = 37), both at rest at 24 hours postoperatively and during coughing at 24 and 48 hours. The number of additional analgesics and incidence of side-effects did not differ between groups. In conclusion, the results of the present study demonstrate that the addition of adrenaline to a combination of fentanyl and bupivacaine improves the quality of epidural analgesia after abdominal surgery. Under the conditions of the study, we did not detect any disadvantage from the addition of adrenaline.

We compared recovery characteristics of propofol anesthesia with those of sevoflurane anesthesia in pediatric outpatients. One hundred and four children, 3 months to 6 years of age, ASA physical status 1 or 2, were randomly assigned to following four groups; sevoflurane (group S), propofol (group P), sevoflurane with premedication (group MS), or propofol with premedication (group MP). Midazolam 0.5 mg.kg-1 and famotidine 1 mg.kg-1 were administered orally 30 min before the induction in the MS and MP group. Recovery from anesthesia, agitation, and postoperative pain were evaluated. The time intervals from the end of surgery to extubation and to discharge from the hospital were recorded. The incidence of vomiting and use of analgesic drugs were also checked. The emergence from anesthesia was slower with propofol anesthesia than with sevoflurane anesthesia, but the time to discharge from the hospital was not significantly different among the four groups. Incidence of agitation was higher in S group compared with P group, but there were no differences between MS and MP. Postoperative pain was similar among the four groups. There were no differences in the incidence of vomiting. Propofol anesthesia provided slower emergence and less agitation compared with sevoflurane anesthesia.

Patient (ASA PS I-III, mean age 68 +/- 14 yr) who had undergone lower extremity surgery under spinal anesthesia were studied to determine the effect of intrathecal administration of morphine 0.1 mg on intra- and postoperative pain relief and its side effects. They were randomly divided into control (C) and intrathecal morphine (M) groups (n = 25, respectively) and received 10 mg tetracaine in 4 ml of a quarter saline with 7.5 micrograms epinephrine. Incidence of intraoperative tourniquet pain was significantly lower in M group (36.8%) than in C group (64.3%). Postoperative pain was examined in terms of the duration until the first supplemental analgesic within 24 hr. The mean duration was 7.0 +/- 4.3 hr in the control group, but 11 patients in the M group needed it within 24 hr (18.1 +/- 6.8 hr, excluding 6 patients who did not receive analgesic). Although incidences of postoperative nausea, vomiting, and itching were higher in M group than in C group, none required antiemetic or naloxone. Both groups showed no difference in postoperative respiratory depression measured by apnea monitor (Eden Trace II, Mallinkrodt Japan, Tokyo). The results suggest that a low dose of intrathecal morphine is effective on postoperative 24 hr pain relief in elderly patients and that its side effects are negligible.

Postoperative pain relief is a growing concern to an anaesthesiologist since no single analgesic is free from side-effects. Moreover, it becomes a challenge after caesarean section delivery to provide postoperative pain relief without much sedation, respiratory depression or problems like nausea, vomiting, so that early baby acceptance and care by mother is promoted. Antinociceptive effect of midazolam is well established by now and its safety is documented. This observation was made in a blind randomised study of 40 women of ASA I/II to evaluate postoperative pain relief using intrathecal midazolam in caesarean section delivery. Group A patients (n=20) received 1.5 ml of 5% lignocaine only and group B patients (n=20) received mixture of 1.5 ml 5% lignocaine with 2 mg midazolam (preservative free) through intrathecal route at L3.4 interspace; vital parameters were monitored intra-operatively and postoperatively and Apgar score of baby in 1st and 5th minute of deliverywas assessed. It was observed intrathecal midazolam produced highly significant (p<0.001) postoperative pain relief together with anti-emetic effect and tranquillity of patients of caesarean section delivery.

This prospective, double-blind, randomized, controlled trial was performed to evaluate the antiemetic effectiveness and side effects of adding droperidol to morphine delivered via a patient-controlled analgesia (PCA) device in 94 women undergoing transabdominal hysterectomy with a standardized anesthetic regimen. They were randomly allocated to receive postoperative PCA as either bolus doses of morphine I mg or a combination of morphine 1 mg and 0.0625 mg droperidol with a lockout interval of 5 minutes and no continuous infusion. The incidence of nausea 6-18 hours postoperatively and 18-24 hours postoperatively was significantly lower in the morphine and droperidol group than in the morphine only group and its severity 2-6 hours, 6-18 hours, and 18-24 hours postoperatively was significantly lower. The number needed to treat to prevent nausea comparing the morphine only group at 6-18 and at 18-24 hours postoperatively were 4 and 4 (95% CI 2-27 and 2-11, respectively). The amount of morphine used 6-18 hours postoperatively in the droperidol group was lower than in the morphine only group. Although the incidence of vomiting and the amount of rescue antiemetics were lower in the morphine and droperidol group, the difference was not statistically significant. Postoperative pain scores were not different between the groups. No patients were oversedated. A series of extrapyramidal reactions were observed in one patient in the morphine and droperidol group. The drug and consumable item cost was not different between the groups. We conclude that droperidol added to morphine in PCA reduces nausea. The appropriate dose of droperidol should be further investigated to reduce the incidence of vomiting.

Postoperative pain management (POPM) remains suboptimal on surgical wards in many countries despite the availability of effective analgesics, new technologies for drug administration, and clinical practice guidelines for pain management. The aim of the present study was to assess remaining long-term effects on pain management routines, patient experiences, and staff member attitudes in surgical wards more than 3 years after introduction of a quality assurance program for POPM and compare the findings to those of an organization where a corresponding systematic, entire hospital, quality assurance program had not been completed. A descriptive and comparative design, based on survey data from both patients (N = 110) and staff members (N = 51) on urologic surgery wards, was used. Significant (p <.05 to p <.0002) overall relationships were observed for identified shortages in pain management routines (lack of preoperative information, inadequate preoperative discussions on pain management, wait for pain killer) and reported experience of pain, nausea, or vomiting in the postoperative period. The quality assurance program, anesthesia-based pain services using a nurse-based anesthesiologist-supervised model, resulted in more adequate pain management routines, better patient satisfaction with POPM, and increased confidence in pain management among nurses on the surgical wards. On the basis of the present study it may be concluded that more than 3 years after the introduction of a quality assurance program for POPM in surgical wards, the pain management routines, patient experiences, and staff member attitudes have remained markedly improved and in accordance with the aims of accepted clinical practice guidelines for surgical pain management.

Institutions with quality management programs need to evaluate the quality of perioperative pain management as well as other aspects of the health service. With the development of anesthesia-based pain services, improvement in this field has been reported. In this prospective study performed in a university hospital, we used a Postoperative Pain Therapy Assessment Questionnaire to quantify the effectiveness of pain therapy and factors affecting the degree of satisfaction and also to pinpoint areas that need improvement. A total of 915 patients who received patient-controlled analgesia for postoperative pain were included in the study; it seems to be the largest patient population from a single hospital. Data were collected as part of the hospital's quality improvement activities. By analyzing the questionnaires, we found that patients were satisfied with the pain therapy performed under the guidance of anesthesiologists, but predictors of satisfaction such as pain intensity and side effects (nausea, vomiting, constipation and difficulty in walking) decreased patient satisfaction considerably. Patients are aware of the fact that health care givers take postoperative care seriously and they do not want any untoward effects interrupting their postoperative care. They are trying to participate in the decision making and also to learn more about pain medicine.

We describe the whole cohort of patients operated on laparoscopically for ventral hernias at our institution. Information on early results, complications, and long-term follow-up was collected prospectively. Of 90 operations attempted, five (5.8%) required conversion. Of the remaining 85 patients, 65 (76%) had an incisional hernia, while 20 (24%) had primary defects. Three trocars were routinely employed (Hasson and two 5-mm). The prosthetic mesh used was ePTFE inserted through the first trocar and fixed using helicoidal staplers. Patients were periodically followed in the outpatient clinic for at least 12 months postoperatively and contacted at the time of this review. Mean operative time was 101 min. We had three small bowel injuries repaired laparoscopically. Postoperative pain was limited. Bowel movements, deambulation, and discharge were prompt. We had six (7%) urinary retentions, eight (9%) seromas, three (3.5%) cases of pneumonia, two (2%) cases of postoperative vomiting, and one (1%) prolonged ileus, which resolved spontaneously on postoperative day 2. Mean postoperative stay was 4 days. One patient was readmitted after 4 weeks with incomplete obstruction, resolved conservatively. There were three recurrences (3.5%), which developed within 1 year of the operation, and a trocar-site herniation (1%). The technique appears safe and efficacious.

Postoperative pain after total knee arthroplasty (TKA) is severe, and achieving adequate analgesia remains a clinical challenge. We tested the hypothesis that, in patients having unilateral TKA under intrathecal (IT) anesthesia, the addition of a femoral nerve block would provide superior analgesia when compared with IT morphine and demonstrate fewer adverse side effects. In a single-blinded and controlled trial, 41 ASA I-III patients undergoing unilateral TKA were randomized into 2 groups. Both groups received 15 mg of IT hyperbaric bupivacaine for the surgical anesthetic. Group ITM received 250 microg of IT morphine and group FNB received an ultrasound-assisted femoral nerve block with 40 mL of 0.5% ropivacaine, 5 microg/mL of epinephrine, and 75 microg of clonidine. At 1, 2, 4, 6, 12, and 24 h postoperatively, we measured visual analog scales for pain, cumulative IV morphine consumption, hemodynamics, and side effects. There were no statistically significant differences in morphine consumption, pain at rest, or pain with movement. However, group FNB had fewer perioperative side effects including nausea, vomiting, and pruritus (P < 0.05 for each event). This corresponded to a decrease in patient satisfaction in group ITM, in which 20% of the patients rated their experience as "unsatisfactory" (P < 0.05). We conclude that, in comparison with IT morphine, a single injection femoral nerve block provides equivalent analgesia but with a significant reduction in side effects for patients having TKA under bupivacaine intrathecal anesthesia.

The effectiveness of postoperative pain relief and the frequency of side effects with three different doses of epidural diamorphine (2.0, 3.5 and 5 mg) was investigated. The study was carried out double-blind in 30 women undergoing awake elective caesarean section. Postoperative pain intensity was measured on a linear analogue scale. The time to onset of analgesia (TOA), time taken to reach a pain score of zero or become comfortable, and time to next analgesia (TNA) were not significantly different between groups. Three patients in the 2 mg group failed to achieve scores of zero but were comfortable. No nausea or vomiting was seen but the incidence of itching was 0, 30% and 80% in the 2.0, 3.5 and 5 mg groups respectively. We conclude that epidural diamorphine 2 mg is adequate for relief of post-caesarean pain and higher doses may increase the incidence of unwanted side-effects.
