Twenty-eight patients scheduled for lung resection with lateral thoracotomy and postoperative chest drains during combined thoracic epidural bupivacaine plus morphine and general anaesthesia were studied. Postoperative pain treatment was continuous epidural infusion of bupivacaine 0.25% 5 ml h-1 plus morphine 0.2 mg h-1 for 48 h and, in addition, the patients received rectal piroxicam 40 mg randomly and double-blind 12 h and 1 h before surgery and 20 mg 24 h-1 postoperatively or placebo. Pain was evaluated at rest, during cough and mobilisation, together with pulmonary function (FEV1, FVC, PEFR) and sensory level of analgesia repeatedly for 48 h. The results showed efficient pain relief, but without differences in pain scores or need for supplementary analgesics between the two groups. Pulmonary function decreased similarly in the two groups. Thus we were unable to show enhanced analgesia by supplementing an otherwise effective low-dose epidural bupivacaine and morphine treatment with piroxicam after thoracic surgery with chest drains.

Twenty-four female patients undergoing sterilization through a minor lower laparotomy received, in a double-blind, randomized study, either lidocaine spray 200 mg or placebo in the surgical wound. Postoperative pain intensity was evaluated on a verbal and a visual analogue scale and wound tenderness with an algometer. During mobilisation from the supine to the sitting position, VAS-score was lower (P less than 0.05) in the lidocaine group 2 h postoperatively, but not 4, 6 and 8 h postoperatively (P greater than 0.05). No significant differences were found in VAS-scores at rest or during cough, or in verbal scale ratings during rest, cough or mobilisation, and postoperative consumption of morphine was similar in the two groups. Pressure pain thresholds were higher (P less than 0.05) 2 h postoperatively in the lidocaine group, but not 4, 6 and 8 h postoperatively. In conclusion, topically applied lidocaine aerosol in the surgical wound leads to very short and clinically insignificant relief of postoperative pain.

Fourteen patients undergoing colorectal surgery received an intraoperative afferent neural block with combined intrathecal and extradural local anaesthetics plus a balanced postoperative low-dose regimen of extradural bupivacaine 10 mg h-1-morphine 0.2 mg h-1 and systemic piroxicam 20 mg/24 h. Postoperative pain, assessed repeatedly during the initial 48 h, was prevented during rest, mobilization from the supine to the sitting position and during walking, in all but one patient; slight pain was observed intermittently during coughing in four patients.

In a double-blind prospective study, 20 patients undergoing major abdominal surgery were allocated randomly to receive a continuous 8-h i.p. infusion of either physiological saline or 0.25% bupivacaine 20 ml h-1 (in saline) following a loading dose of saline 1 ml kg-1 or 0.25% bupivacaine 1 ml kg-1 on entering the peritoneum. The following variables were measured before and at 2-h intervals during the infusion: serum glucose and cortisol concentrations, forced vital capacity, forced expiratory volume in the first second, peak expiratory flow rate and pain at rest, on mobilization and on coughing (visual analogue scale). Postoperative pain, impairment in pulmonary function and increase in serum cortisol and glucose concentrations were not influenced by the i.p. infusion of bupivacaine when compared with saline. This study shows that the i.p. instillation of therapeutically safe doses of bupivacaine was without effect in the management of pain, postoperative pulmonary dysfunction and the stress response in this group of patients.

Postoperative pain was treated by epidural administration of 30 to 50 mg pethidine (5 mg X ml-1) in a group of 36 patients who had undergone retropubic prostatectomy. Surgery was carried out under epidural anaesthesia with lidocaine. Pain was assessed by means of the visual analogue scale. A general study of the effects of injections and reinjections showed that analgesia thus obtained was excellent at the first hour after injection and lasted 3 to 5 h. The effect of the first postoperative injection on spontaneous pain was studied in 14 patients. Statistical analysis (Wilcoxon test) demonstrated that the fall in pain score was significant at the first and third hours after injection, but not significant at the fifth hour. The analgesia to that pain produced by coughing was studied in 11 patients. There was a significant decrease in pain at the first hour after injection; differences in pain scores at the third hour were not significant. No noticeable side-effect was observed. It was concluded that low doses of epidural pethidine were efficient on postoperative pelvic abdominal pain, but that doses should be increased if painless coughing was required.

Remifentanil is a new, esterase-metabolized opioid for anesthesia. Nonspecific esterases terminate the drug effect, with a context-sensitive half-time which plateaus at 3-4 min. This dose-ranging pilot study was designed to estimate the dose requirement of remifentanil for abolition of the responses to skin incision and intraoperative stimuli, and to determine the speed of recovery. Fifty-one unpremedicated patients took part at two centers. Anesthesia was induced with propofol, 67% nitrous oxide, and vecuronium. Remifentanil was then given (1 microgram/kg, plus an infusion of 0.0125-1.0 micrograms.kg-1.min-1). Responses were defined as: > 15% increase in systolic blood pressure or > 20% increase in heart rate, tearing, sweating, movement, or coughing. Responses to incision or surgery were treated with 0.5 micrograms/kg remifentanil boluses and a 50% increase in infusion rate, which could be done twice. Subsequent responses were treated with propofol or isoflurane. Remifentanil and nitrous oxide administration were terminated after the incision was closed. ED50 for response to skin incision varied between the two study sites (0.020 and 0.087 microgram.kg-1.min-1). ED50 for response to all surgical stimuli was 0.52 microgram.kg-1.min-1. At 0.3 microgram.kg-1.min-1 or more, only 3 of 21 patients required isoflurane. Recovery was not longer in patients receiving larger doses to spontaneous ventilation (2.5-4.6 min), tracheal extubation (4.2-7.0 min), and response to verbal command (3.0-4.6 min). Postoperative pain was reported in most patients (92%) at a median time of 21 min. We conclude that remifentanil was effective and well tolerated as a component of nitrous oxide-opioid-relaxant anesthesia.(ABSTRACT TRUNCATED AT 250 WORDS)

In a double-blind, randomized study, 32 patients scheduled for elective inguinal herniotomy under general anaesthesia received subcutaneous infiltration with 40 ml ropivacaine 2.5 mg/ml or bupivacaine. Postoperative pain intensity was assessed repeatedly for 24 hours at rest, during cough and movement on a visual analogue scale (VAS) and by means of pressure algometry. No differences between pain intensities or wound tenderness were found between the groups. The demand for analgesics was similar in the two groups. We conclude that incisional ropivacaine is as effective as bupivacaine in the management of post-herniotomy pain.

Thirty-six patients undergoing elective thoracotomy with pulmonary resection with the use of combined epidural and general anesthesia were randomized into a double-blind study to receive a single intravenous preoperative dose of methylprednisolone 25 mg/kg body weight or a placebo (saline solution). Postoperative pain relief consisted of epidural morphine 4 mg and paracetamol 1 gm three times a day for 4 days. Postoperative pulmonary function (peak expiratory flow rate, forced expiratory volume in first second, forced vital capacity) was evaluated on days 1, 2, 3, 4, and 7 and after 1 month. The value obtained after 1 month served as the control value. Pain score at rest and during cough was evaluated after 4 and 8 hours and on days 1, 2, 3, and 4. Pulmonary function was reduced after operation to the same degree in the steroid and placebo group: 42% versus 41% for forced expiratory volume in first second and 38% versus 39% for forced vital capacity, compared with control values after 1 month. Pain score was reduced in the steroid group after 4 hours and on day 1 during rest and after 4 and 8 hours and on day 2 during cough, compared with results in the placebo group (p < 0.05). In the steroid group three patients underwent reoperation because of leakage through the chest wall incision. In conclusion, administration of a single preoperative dose of methylprednisolone did not affect the postoperative reduction in pulmonary function after thoracotomy despite attenuated pain response, and the results do not warrant steroid administration before lung operation.

We compared wound infiltration with small-dose tenoxicam (7.5 mg) to intramuscular (IM) administration of the same dose to treat pain after herniorrhaphy. In a randomized, double-blind study, 50 patients received either preoperative wound infiltration with tenoxicam, 7.5 mg in 40 mL of 0.9% saline (WI group; n = 25) or IM tenoxicam 7.5 mg (IM group; n = 25). In each group a saline placebo of equal volume was given by the alternate route, i.e., those who received wound infiltration with tenoxicam received 0.75 mL of 0.9% saline IM; those who received IM tenoxicam received 40 mL of 0.9% saline for wound infiltration. Postoperative pain was assessed with a verbal pain scale and a visual analog scale (VAS) at rest and during movement and cough, 1, 2, 4, 6, and 24 h postoperatively. Wound tenderness was assessed with an electronic algometer preoperatively, and 2, 4, and 6 h postoperatively. The need for supplementary analgesics (acetaminophen and morphine) was registered. No differences were observed between groups in VAS pain scores, verbal rating pain scores, pain pressure thresholds, or in need for supplementary analgesics. We conclude that tenoxicam 7.5 mg has no local analgesic effect on postoperative pain after herniorrhaphy.

The feasibility of day case laparoscopic cholecystectomy was assessed in unselected patients using a standard anaesthetic protocol. Postoperative pain and nausea were assessed at 6 and 24 h postoperatively (visual analogue scale, range 0-10). Thirty-two patients were studied (23 female, 9 male, mean age 49.6 years). The mean duration of surgery was 68 min. At 6 h after surgery, 10 patients (31%) had no pain at rest. For the group as a whole, the median pain score was 3 at rest (range 0-6), 4 on movement (0-9), and 5 on coughing (0-9) and eight patients (25%) were nauseated. At 24 h, 15 (46.9%) had no pain at rest. For the group as a whole, the median pain score was 1 at rest (0-7), 3 (0-6) on movement and 3 on coughing (0-9). The same eight patients were nauseated. Ten patients (31.3%) were judged fit for discharge at 6 h, and 28 (87.5%) by 24 h. There was no statistical difference in mean age or duration of surgery in those judged fit for early discharge compared to the study group as a whole. Nausea was an important factor in those unfit for discharge at 24 h. Selection criteria might improve these figures. From the results of our study, 24 h admission is a more realistic goal and will be suitable for most patients requiring laparoscopic cholecystectomy.
