The obstetrical anaesthesia experience of the Winnipeg Women's Hospital from 1975 to 1983 was reviewed (n = 22,925 infants). Use of narcotics in labour for analgesia decreased from 38.7 to 18.3 per cent of the deliveries. For analgesia during spontaneous vaginal deliveries, epidural anaesthesia increased from 6.0 to 24.0 per cent, inhalational analgesia decreased from 53.7 to 3.2 per cent while "no anaesthetic intervention" rose from 40.3 to 72.8 per cent. Use of epidural anaesthesia for Caesarean section increased from 58.7 to 82.6 per cent. The most common acute complications of anaesthesia were hypotension and inadvertent dural puncture during epidural catheterization. The incidence of hypotension decreased from 28.3 to 17.4 per cent during the nine-year period. Dural puncture decreased from 4.7 to 1.1 per cent of all epidural administrations. Postpartum complaints (that were thought to be related to anaesthesia) were mainly headache, back pain and sore throat. The incidence of these complaints also decreased over the study period.

In a prospective study of 76 children aged between 18 months and 13 years, 40 children underwent tonsillectomy using the traditional blunt dissection technique with bipolar diathermy to establish haemostasis while 36 children underwent tonsillectomy where bipolar diathermy alone was used to dissect out the tonsils. Blood loss was significantly reduced in the diathermy dissection group (10.5 ml +/- 2.05, diathermy dissection, 33.56 ml +/- 1.95, blunt dissection, P < 0.05). More analgesia was required in the diathermy dissection group prior to hospital discharge (P = 0.01). The diathermy dissection group took a significantly longer period of time to re-establish a normal diet (7.07 days +/- 0.44, diathermy dissection, 5.15 days +/- 0.36, blunt dissection, P = 0.001). Fifteen percent of children in the blunt dissection group and 31% in the diathermy dissection group were taken to the general practitioner between days 3-10 because of sore throat, poor oral intake or otalgia. Twenty two point four percent of children overall were prescribed antibiotics. This recently described technique of bipolar diathermy dissection could be a useful technique in selected cases such as the very small or those with a bleeding diathesis but is associated with increased postoperative morbidity and requires good postoperative analgesia.

A prospective randomized study was undertaken on elderly patients undergoing intraocular, predominantly cataract, surgery to compare the intraoperative, recovery and postoperative features associated with general anaesthesia employing either the spontaneous (SV) or controlled ventilation (IPPV) techniques of respiration using isoflurane, nitrous oxide and a constant FiO2 of 0.33. SV patients received isoflurane 0.97% (mean). IPPV patients were intubated with atracurium alone, and received isoflurane 0.60% (mean). Heart rates were lower intraoperatively with IPPV, and blood pressures were lower with SV. Intraocular pressure measurement identified three subgroups of patients within each respiratory group: a large subgroup (70% of SV, 64% of IPPV patients) with a high-normal initial mean intraocular pressure which fell intraoperatively; a small subgroup (25% of SV, 24% of IPPV patients) with a low normal initial mean intraocular pressure which rose intraoperatively; and a small subgroup (5% of SV and 11% of IPPV patients) in whom the intraocular pressure remained unchanged. A satisfactory operative field was reported by surgeons in 87% of SV and in 86% of IPPV patients. SV patients had a lower mean end-operative SaO2 than IPPV patients (SV 95.0%; IPPV 96.7%), and were extubated sooner at the end of anaesthesia. In the recovery ward the times to awakening, vomiting incidences, analgesic usages and recovery times were similar, and patients were similarly restful. Postoperatively, the incidences of vomiting, headache, fever, sore throat and myalgia were similar, but SV patients required more analgesia for headache. We conclude that both technique properly performed are similarly satisfactory for cataract surgery in elderly patients.

In a prospective study of 150 patients randomly assigned to three groups, we have compared the incidence and duration of sore throat after a standard anaesthetic regimen using three different methods of airway management: facemask; laryngeal mask, and laryngeal mask with insertion aid. The insertion aid is currently being developed by Portex Ltd and is intended both to facilitate accurate placement of the laryngeal mask and to reduce trauma during insertion. All the patients were women undergoing short operative procedures requiring minimal postoperative analgesia. The incidence of sore throat was significantly less with a facemask (8%) than with the laryngeal mask when used without the insertion aid (28.5%) (p < 0.02). When using the insertion aid the incidence was 18% and this was not statistically different from the facemask. The presence of blood on the laryngeal mask (22%) was less likely when the insertion aid was used (4%) (p < 0.02).

The definition and detection of the onset of analgesic drug activity represent two of the more complicated methodologic challenges in clinical pharmacology. We addressed these issues by designing an analgesic assay with frequent posttreatment assessments to identify the first time when a subject experienced relief and when a nonprescription-strength analgesic could be distinguished from placebo. To test the feasibility of conducting this assay, 29 subjects with acute sore throat were randomized to receive 200 mg ibuprofen, 400 mg ibuprofen, or placebo under double-blind conditions. To identify the onset of analgesia, subjects used three rating scales at 5-minute intervals over the first hour. Subjects completed each series of assessments efficiently, most within 5 seconds. Each active agent was differentiated from placebo early after treatment (p < or = 0.05), and there was dose-separation. We conclude that the sore throat pain model can be used to evaluate the onset of action of nonprescription-strength analgesic agents.

Ninety-two adult patients scheduled for automated percutaneous discectomy (PERC) were assigned to receive either local anesthesia supplemented with monitored i.v. analgesia (MIVA) or general endotracheal anesthesia (GA-LITE). Patients were examined 1 week post-PERC for the presence of new paresthesias, and they completed a questionnaire 6-18 weeks after PERC about changes in their pain. Sixty-four percent of MIVA patients and 83% of GA-LITE patients had diminished pain following PERC. Results did not show any difference between the two groups for new paresthesias after PERC. There were no differences in postoperative pain medication requirements, but the GA-LITE group reported more postoperative nausea, vomiting, and sore throat. GA-LITE patients averaged 1.06 +/- 0.3 h in the recovery room compared with 0.70 +/- 0.3 h for MIVA patients. Although the use of general anesthesia for PERC has been contraindicated because of fear of damaging the nerve root in the sleeping patient, we conclude that general anesthesia does not increase nerve injuries attributable to instrumentation. However, general anesthesia did cause a higher incidence of minor complications such as nausea, vomiting, and sore throat in the immediate postoperative period than did MIVA.

A 53-year-old white woman presented with a 5-month history of throat pain. The soft palate was biopsied and histological examination confirmed the diagnosis of infiltrating squamous cell carcinoma. She refused surgery and radiotherapy and was therefore offered photodynamic therapy which she accepted. She was treated with 20 J/cm2 at 100 m W/cm2 over a 3 cm area. She was discharged three days later having made an uncomplicated recovery, though substantial analgesia was required. Healing was complete after 2 months, with no loss of palatal function and at most recent follow-up (16 months) there was no sign of residual disease and she remained well.

Two hundred and thirty-one patients were questioned the day following their cataract surgery to ascertain the incidence of postoperative morbidity. One hundred and nineteen patients received local anaesthesia (LA) and 112 received general anaesthesia (GA). There was a significant difference in the incidence of nausea (21% in GA group, 3% in LA group, p < 0.01), sore throat (41% GA group, 3% LA group, p < 0.01), and bruising of the eye (15% GA group, 39% LA group, p < 0.01). There was no significant difference in the incidence of vomiting, headache, double vision, the severity of postoperative pain, or the need for analgesia. The time before the patients drank and ate postoperatively was significantly shorter in the local anaesthetic group (1.3 h and 1.8 h LA group, 4.1 h and 6.7 h GA group respectively, p < 0.01).

Inguinal herniorrhaphy is commonly performed on an outpatient basis under nerve blocks or local or general anesthesia (GA). Our hypothesis is that use of paravertebral blocks (PVB) as the sole anesthetic technique will result in shorter time to achieve home readiness and improved same-day recovery over a 'fast-track' GA. Fifty patients were randomly assigned to receive either PVB or GA under standardized protocols (PVB = 0.75% ropivacaine, followed by propofol sedation; GA = dolasetron 12.5 mg, propofol induction, rocuronium, endotracheal intubation; desflurane; bupivacaine 0.25% for field block). Eligibility for postanesthetic care unit (PACU) bypass and data on time-to-postoperative pain, ambulation, home readiness, and incidence of adverse events were collected. More patients in the PVB group (71%) met the criteria to bypass the postanesthetic care unit compared with patients in the GA group (8%; P < 0.001). Only 3 (13%) of patients in the PVB group requested treatment for pain while in the hospital, compared with 12 (50%) patients in the GA group, despite infiltration with local anesthetic (P = 0.005). Patients in the PVB group were able to ambulate earlier (102 +/- 55 minutes) than those in the GA group (213 +/- 108 minutes; P < 0.001). Time-to-home readiness and discharge times were shorter for patients in the PVB group (156 +/- 60 and 253 +/- 37 minutes) compared with those in the GA group (203 +/- 91 and 218 +/- 93 minutes) (P < 0.001). Adverse events (e.g., nausea, vomiting, sore throat) and pain requiring treatment in the first 24 hours occurred less frequently in patients who had received PVB than in those who had received GA. In outpatients undergoing inguinal herniorrhaphy, PVB resulted in faster time to home readiness and was associated with fewer adverse events and better analgesia before discharge than GA.

In a randomised double blind prospective study, we tested the hypothesis that postoperative pain is lower in patients who receive an ProSeal LMA laryngeal mask airway compared with a tracheal tube. One hundred consecutive female patients (ASA I-II, 18-75 years) undergoing laparoscopic gynaecological surgery were divided into two equal-sized groups for airway management with the ProSeal LMA or tracheal tube. Anaesthesia management was identical for both groups and included induction of anaesthesia using propofol/fentanyl, and maintenance with propofol/remifentanil, muscle relaxation with rocuronium, positive pressure ventilation, gastric tube insertion, dexamethasone/tropisetron for anti-emetic prophylaxis, and diclofenac for pain prophylaxis. All types of postoperative pain were treated using intravenous patient-controlled analgesia (PCA) morphine. Patients and postoperative staff were unaware of the airway device used. Data were collected by a single blinded observer. We found that pain scores were lower for the ProSeal LMA at 2 h and 6 h but not at 24 h. Morphine requirements were lower for the ProSeal LMA by 30.4%, 30.6% and 23.3% at 2, 6 and 24 h, respectively. Nausea was less common with the ProSeal LMA than with the tracheal tube at 2 h and 6 h but not at 24 h. There were no differences in the frequency of vomiting, sore throat, dysphonia or dysphagia. We conclude that postoperative pain is lower for the ProSeal LMA than the tracheal tube in females undergoing gynaecological laparoscopic surgery.
