The analgesic effect of subarachnoid administration of tetracaine combined with low dose morphine or nalbuphine for spinal anesthesia was evaluated in 60 ASA physical status class I or II patients. Dextrose solution (10%) was added to 0.4 mg morphine or 0.4 mg nalbuphine to make a total volume of 2 ml, which was injected intrathecally with tetracaine in a double-blind, randomized fashion. Vital signs, sensory level, motor block, pain score, and side effects were recorded every 2 min for the first 15 min and then at 15, 30, 45, and 60 min and at 30-min intervals until the patient complained of pain. Side effects and opioid requirements were recorded for the first 24 h. Complete analgesia (time from injection to first report of pain) lasted 180 +/- 51.6 min in the control group and increased to 238 +/- 71 min in group with addition of 0.4 mg nalbuphine, 250 +/- 74 min in group with addition of 0.4 mg morphine (p less than 0.05). The effective analgesia (time from injection to first opioid requirement) also increased in groups of nalbuphine and morphine than the control group. No differences in complete or effective analgesia was found between groups in the presence of nalbuphine or morphine. Results indicate that the addition of 0.4 mg nalbuphine or morphine to hyperbaric tetracaine for spinal anesthesia improves the quality of intraoperative analgesia and can last into the postoperative period. Side effects were less in nalbuphine group than with morphine group.

Circumcision often followed by severe pain during the postoperative period. Forty boys, ASA class I, presenting for day case circumcision were allocated randomly to receive either 4% prilocaine hydrochloride spray or 1.1% dipucaine ointment at the end of the operation. Analgesia was assessed by a single observer utilizing a three-point scale in recovery room. The parents were asked to complete the questionnaire 8h following operation and on the morning of the first postoperative day. At approximately 24h following operation an assessment of the child's activity level was made by the parents. The frequency of taking the oral analgesia was also recorded. Both topical analgesics provided satisfied analgesia during the postoperative period and no complication was noted. Only one patient in dipucaine group vomited in the recovery room. We conclude that topical use of prilocaine hydrochloride and dipucaine can provide a simple, safe and adequate analgesia for post-circumcision pain relief.

The incidence of hypotension induced by spinal anesthesia in 154 ASA class I or II patients having Cesarean section and postpartum bilateral tubal ligation was studied. Xylocaine (2%) 60-65 mg was used for spinal anesthesia. There was 41.0% of patients in Cesarean section group developed hypotension induced by spinal anesthesia, and 13.5% in tubal ligation group. We found no correlation between the time after delivery and the occurrence of hypotension induced by spinal anesthesia. In addition, 20.3% of the patients in tubal ligation group required intravenous narcotics because of inadequate sensory blockade during skin incision, but only 9.0% in Cesarean section needed the same supplement which was due to visceral pain during intra-abdominal manipulation. We conclude that spinal anesthesia with 2% xylocaine is safe and effective in both Cesarean section and postpartum tubal ligation although a significant difference of spinal hypotension existed.

In an attempt to reduce the dose of local anesthetic during intravenous (IV) regional anesthesia of the upper limb, we combined 100 mg of lidocaine with 0.05 mg of fentanyl and 0.5 mg of pancuronium. The study was designed in a randomized, double-blind fashion to determine the efficacy of this approach in providing analgesia and relaxation during surgery and to evaluate its safety after immediate deflation of the tourniquet following IV drug injection. Eighty unpremedicated patients, ASA physical status I or II, were assigned to the following groups: group A (n = 15) received 100 mg of lidocaine diluted in 40 mL of NaCl IV; groups B-D (n = 15 in each group) received 100 mg of lidocaine diluted in NaCl, with the addition of 0.05 mg of fentanyl (group B) or 0.5 mg of pancuronium (group C), or both (group D) to a total volume in all groups of 40 mL. Patients in groups A-D underwent elective operations on the forearm, wrist, and hand; for evaluation of safety, in 20 volunteers (group E) the tourniquet was immediately released after IV injection of the three drugs at the previously described doses. The analgesic effect was more profound in group D compared with groups A-C. In group D, 9 of 15 patients had excellent analgesia. In six patients, pain was experienced at the beginning of surgery, but 5 min thereafter patients remained pain free.(ABSTRACT TRUNCATED AT 250 WORDS)

We studied 114 female patients (ASA 1 or 2) who were within 20% of ideal body weight and who were scheduled to undergo gynaecological laparoscopy which required supplementation with an opioid (groups IA and PA), or dental procedures which did not require opioid supplementation (groups IO and PO). A computerised package of psychomotor tests was performed before surgery. Anaesthesia was induced with propofol 2.5 mg.kg-1 and all patients received atracurium 0.3 mg.kg-1 and 67% nitrous oxide in oxygen. Patients in group IA received isoflurane 1% (inspired), and alfentanil 10 micrograms.kg-1 as a bolus and 10 micrograms.kg-1.h-1 as an infusion. Patients in group PA received propofol 9 mg.kg-1.h-1 as an infusion, decreasing to 6 mg.kg-1.h-1 after 15 min, together with alfentanil 10 micrograms.kg-1.h-1. Patients in groups IO and PO received isoflurane and propofol in the regimens described for groups IA and PA, but without alfentanil. Recovery was assessed by a blinded observer who recorded times to awakening (eye opening) and orientation (giving date of birth), and who repeated the psychomotor tests at 1, 3 and 5 h. Linear analogue scales of mood, nausea and pain were obtained and other side effects were noted in the succeeding 48 h. A matched control group of 25 females (who were not anaesthetised) underwent psychomotor testing on four occasions in order to assess the 'learning effect' of repeated recovery testing. The analysis of recovery tests did not assume a normal distribution.(ABSTRACT TRUNCATED AT 250 WORDS)

A double-blind placebo controlled trial of 5% 5-aminosalicylic acid (5-ASA) cream for the treatment of oral aphthous ulcers was carried out on 22 subjects. The cream or a placebo (11 patients each) was applied to the ulcers three times daily for up to 14 days. Daily discomfort was reduced by half (P less than 0.01) and less pain (P less than 0.05) was experienced by the treated group. Treatment with 5-ASA shortened healing time (7 vs. 11 days, P less than 0.01) and reduced the difficulty in eating (P less than 0.05). No significant side-effects were reported. We believe 5-ASA cream to be an effective treatment for aphthous ulcers.

The intraoperative use of opioid analgesics decreases the volatile anesthetic requirement and provides for pain relief in the early postoperative period. In a randomized double-blind, placebo-controlled study involving 95 ASA physical status 1 or 2 children (ages 5-15 yr) undergoing general anesthesia for elective operations, we compared postoperative analgesia following the intraoperative intravenous (iv) administration of ketorolac, a nonsteroidal antiinflammatory drug or morphine, an opioid analgesic. After induction of general anesthesia and before the start of the surgical procedure, children received equal volumes of saline, morphine (0.1 mg.kg-1, iv) or ketorolac (0.9 mg.kg-1, iv). Postoperative pain was evaluated by the child using a 10-cm linear visual analog scale (VAS) and by a blinded observer using both a VAS and an objective pain scale (OPS) in the postanesthesia care unit (PACU). There were no statistically significant differences in the VAS and OPS scores in the PACU or in the postoperative analgesic requirements in children receiving morphine or ketorolac. The placebo group had a significantly higher VAS and OPS score and required earlier and more frequent analgesic therapy in the PACU compared to the two analgesic groups. Patients receiving ketorolac had less postoperative emesis than those receiving morphine. We conclude that ketorolac (0.9 mg.kg-1) is an effective alternative to morphine (0.1 mg.kg-1) as an iv adjuvant during general anesthesia, and in the dose used in this study, is associated with less postoperative nausea and vomiting in children.

In a randomized double-blind study, the effects of clonidine premedication as a sedative, anxiolytic, analgesic and oculohypotensive agent were studied in 100 elderly patients (62 to 65 +/- 10 years, ASA grade I-II) undergoing elective intraocular surgery under local anaesthesia. The control group (Group A, n = 50) received oral diazepam 0.15 mg/kg 120 min before surgery and Group B (n = 50) received oral clonidine 300 micrograms 120 min before surgery. Two hours after the premedication, there was significantly more sedation (P less than 0.05) and less subjective anxiety (P less than 0.05) in the clonidine group than in the control group. There was a significant fall in intraocular pressure (IOP) from 20 +/- 0.5 to 13 +/- 0.5 mmHg (P less than 0.05) and significant reduction in systolic and diastolic blood pressure (BP) and heart rate (HR) (P less than 0.05) in the clonidine group as compared to the control group. Perioperatively, significantly more supplementation with i.v. diazepam was given in the control group than in the clonidine group (P less than 0.01). The incidence of intra-operative hypertension (P less than 0.01) and tachycardia (P less than 0.05) was significantly greater in the control group than in the clonidine group. A significantly larger number of patients in the clonidine group scored a Post-Anaesthesia Recovery (PAR) score of 10 as compared to the control group (P less than 0.01). There was no statistical difference in the postoperative Visual Analogue Scale (VAS) scores for pain, number of analgesic requests and emesis.(ABSTRACT TRUNCATED AT 250 WORDS)

Propofol is associated with a low incidence of postoperative nausea and vomiting. In a prospective, randomized, double-blind, placebo-controlled study, we investigated the possible direct antiemetic properties of a subhypnotic dose of propofol. Fifty-two ASA physical status I or II patients, aged 15-60 yr with nausea and vomiting after minor gynecologic, orthopedic, or digestive tract surgery, were included in the study and received either propofol (10 mg = 1 mL) or placebo (1 mL Intralipid) intravenously in the postanesthesia care unit. Patients treated with propofol experienced a larger reduction in nausea and vomiting than patients treated with placebo (81% vs 35% success rate; P less than 0.05). Patients successfully treated had a similar incidence of relapse (propofol 28%; placebo 22%) within the first 30 min after therapy. Thirty-three percent of the propofol-treated patients and 44% of the placebo-treated patients showed a minor increase in sedation. The level of postoperative pain did not change in either group. Hemodynamic values remained unchanged in both groups. Pain on injection (7.6%) or dizziness (3.6%) only occurred in the propofol group. We conclude that propofol has significant direct antiemetic properties.

The effects of varying the strength of bupivacaine used in epidurals for the relief of labour pain was examined. The trial randomly allocated sixty women in the first stage of labour to one of three groups. All women were of ASA status 1 or 2 and had uncomplicated pregnancies. Subjects in each group received pethidine 25 mg in 10 ml of either 0.125%, 0.1875%, or 0.25% bupivacaine. Pain scores for each patient were then assessed over the following thirty minutes. Duration of analgesia and subsequent dose requirements were examined. No difference in pain scores between groups at thirty minutes after injection of the test solutions was found. The 0.25% solution group did however have a more rapid onset of analgesia with the majority of patients in this group achieving their maximum effect between ten and twenty minutes after injection. Duration of analgesia was not prolonged by using the stronger solutions. This study suggests that when epidural pethidine 25 mg is added to local anaesthetic solutions of bupivacaine, adequate analgesia for the first stage of labour is achieved with the 0.125% bupivacaine solution. The use of stronger solutions of bupivacaine achieves no greater degree of analgesia nor longer duration of action, although the onset of analgesia may be faster with the stronger solutions. Further investigations are needed to determine if 25 mg of pethidine is the best choice of dose to use under these circumstances.
