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.

1. Single doses (500 and 1000 mg) of both buffered aspirin and aspirin tablets were compared with placebo in a randomised double-blind trial of parallel design in patients with postoperative pain after third molar surgery. 2. Only buffered aspirin 500 mg provided significant pain relief (P = 0.016) during the 5 h investigation period. 3. A significant correlation (P = 0.004) was observed between overall pain scores after the various aspirin treatments and aspirin esterase activity. 4. Buffered aspirin preparations afforded a slight advantage over aspirin tablets in the control of postoperative pain after third molar surgery. However, the duration of analgesia was short (approximately 2 h). 5. Aspirin esterase activity appears to be an important determinant of the drug's efficacy in postoperative dental pain.

Topical aspirin/diethyl ether (ADE) mixture was used to treat 45 consecutive patients with acute herpetic neuralgia (AHN) (n = 28) and with post-herpetic neuralgia (PHN) (n = 17) in an open-label study. Good-to-excellent results were achieved by 93% of AHN patients and by 65% of PHN patients. Earlier treatment yielded better results for the AHN but not the PHN group. The topical treatment seemed to accelerate the healing of acute herpetic skin lesions and possibly modulate the severity of the herpetic infection. Furthermore, a striking reduction in the percentage of AHN patients developing PHN was observed in the treated group, as compared with the disease natural history reported in the literature (4 vs. 50-70%). Treatment tolerance was excellent with no adverse effect observed. In addition to the open trial, a pilot double-blind crossover placebo-controlled study (n = 11) compared the analgesic efficacy of ADE with two other NSAID (indomethacin and diclofenac) drug/ether mixtures. Aspirin (but not indomethacin and diclofenac) was significantly superior to placebo as regards pain relief (P less than 0.05).

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.

The effect of 20 mL of intraarticular bupivacaine (0.25%, with or without 1:200,000 epinephrine), morphine (0.03%, with or without 1:200,000 epinephrine), or normal saline on postoperative analgesia after arthroscopic knee surgery was studied in a randomized, prospective, double-blind trial in ASA I-III outpatients receiving general anesthesia (n = 112) or regional anesthesia (n = 27 [spinal (n = 25) or epidural (n = 2)]). The visual analogue pain scores in the postanesthesia care unit and 3, 6, 12, and 24 h after surgery, time to first analgesic use, and total 24-h analgesic requirements were recorded. In those who received general anesthesia, the visual analogue scores were significantly lower in the bupivacaine group compared with both the morphine- and placebo-treated patients (P less than 0.05). The time to first analgesic use was longer in both the bupivacaine and morphine groups when compared with the control group (P less than 0.05). No significant differences were detected in total 24-h analgesic requirements among the groups. Patients who had received regional anesthesia had lower visual analogue scores compared with patients who had received general anesthesia irrespective of the intraarticular treatment (P less than 0.05). Our results indicate that intraarticular injection of bupivacaine after arthroscopic knee surgery provides prolonged analgesia but that there is no significant prolonged analgesia provided by intraarticular morphine.

We report a case of mitral valve prolapse in which the first manifestation was the occurrence of arrhythmias during anesthesia. A 28 years old female patient, ASA I, without previous medical or surgical history was programmed for surgical repair of an anal fistula. Preoperative physical and laboratory examination were normal. During anesthetic induction with propofol and droperidol and coinciding with orotracheal intubation the patient developed ventricular premature beats, bigeminy, and runs of ventricular tachycardia which were controlled with intravenous lidocaine. Anesthesia was maintained with 66% of O2/N2O, 0.5 to 1% of isoflurane, alfentanil, and atracurium. At the beginning of the intervention the patient presented an episode of supraventricular tachycardia at a rate of 140 to 160 beats/min which did not respond to a deeper anesthetic level nor to the administration of 5 mg of verapamil. This arrhythmia was finally interrupted with 3 mg of propranolol and it did not relapse during the surgical procedure. We discuss the physiopathology of the lesion, the possible arrhythmic effect of the anesthetic agents used in this case, and the effects of several pathologic situations (anemia, pain, anxiety, hypovolemia, etc) documented in patient with this abnormality.
