The cardiovascular response to fiberoptic oral intubation under total intravenous anaesthesia with propofol or a balanced volatile technique with thiopentone/enflurane was compared in 50 patients of physical status ASA 1 and 2 who were scheduled for elective ear, nose and throat surgery. Patients were randomly assigned to receive propofol or enflurane. There was no significant difference between the two anaesthetic techniques in haemodynamic profile either before, during or after fibreoptic intubation (the study design was adequate to detect a 20% difference with > 90% statistical power), in incidence of postoperative sore throat or in time taken for intubation. In no patient did the oxygen saturation decrease to below 95% or the CO2 tension exceed 5.8 kPa.

Laser ablation of the palatine tonsils is a useful alternative to tonsillectomy in adults. Cryptic tonsillitis is a common problem causing recurrent infection, sore throat, and halitosis. Elimination and/or obliteration of surface pockets (crypts) of the palatine tonsils utilizing the CO2 laser was effective in 86 patients treated in the past 4 years. Ablation of the tonsil surface was performed in stages under local anesthesia in an office setting; CO2 laser energy delivered through the "SwiftLase" handpiece extension provided char-free, superficial layer ablation of tissue. "SwiftLase" is easily installed onto existing CO2 laser units and provides high-power densities by utilizing a focused laser beam in an extremely fast uniform scan over an extended area (up to 4 mm) within a fraction of a second. This method and results of its use are discussed.

We compared 2% lignocaine gel with saline as a lubricant for the laryngeal mask airway in 126 patients receiving positive pressure ventilation in whom cuff pressures were limited to 60 cmH2O and peak airway pressures to less than 17 cmH2O. The incidence of sore throat was similar for both groups and there were no emergence problems. There were significantly more intra- and postoperative complications in the lignocaine group (p < 0.05) but the frequency of sore throat was similar when the device was inserted at the first attempt. Positive pressure ventilation to normal end-tidal CO2 values was possible in all patients. Lignocaine gel is an unsuitable lubricant for the laryngeal mask airway. Cuff pressure limitation to 60 cmH2O does not necessarily impede ventilation and may be an important factor in reducing emergence and postoperative complications.

Higher indoor concentrations of air pollutants due, in part, to lower ventilation rates are a potential cause of sick building syndrome (SBS) symptoms in office workers. The indoor carbon dioxide (CO2) concentration is an approximate surrogate for indoor concentrations of other occupant-generated pollutants and for ventilation rate per occupant. Using multivariate logistic regression (MLR) analyses, we evaluated the relationship between indoor CO2 concentrations and SBS symptoms in occupants from a probability sample of 41 U.S. office buildings. Two CO2 metrics were constructed: average workday indoor minus average outdoor CO2 (dCO2, range 6-418 ppm), and maximum indoor 1-h moving average CO2 minus outdoor CO2 concentrations (dCO2MAX). MLR analyses quantified dCO2/SBS symptom associations, adjusting for personal and environmental factors. A dose-response relationship (p < 0.05) with odds ratios per 100 ppm dCO2 ranging from 1.2 to 1.5 for sore throat, nose/sinus, tight chest, and wheezing was observed. The dCO2MAX/SBS regression results were similar.

With the increased utilization of school buildings on a year-round basis, school indoor air quality has become a national concern. The purpose of this study was to evaluate possible associations between ventilation system type and occupant perception of indoor air quality. Staff (n = 403) from 12 schools completed a self-administered questionnaire. Carbon dioxide (CO2) levels, air exchange rates, and particle counts were also measured for each school. Schools with unit ventilator (UV) systems had the lowest mean CO2 level at 637 ppm, followed by the variable air volume (VAV) systems with 664 ppm, and constant volume (CV) systems with a mean of 703 ppm. Schools with UV systems had the lowest mean air exchange rate at 2.67 air changes per hour (ACH), followed by the VAV system type at 2.80 ACH and the CV system type at 4.61 ACH. Indoor versus outdoor particle ratios were calculated for each ventilation system type. Particles with aerodynamic diameters ranging from 0.1-1.0 microm had a geometric mean ratio ranging from 0.38 to 0.68; particles with aerodynamic diameters ranging from 1-3 microm had ratios ranging from 1.39 to 5.47, and particles with aerodynamic diameters greater than 3 microm had ratios ranging from 3.20 to 14.76. Schools using VAV systems had a significantly lower prevalence of red and watery eyes while schools with UV systems had an elevated prevalence of nasal congestion, sore throat, headache, and dustiness complaints. This increased prevalence of complaints in buildings with UV systems may be due to the increased particulate levels.

We compared the laryngeal mask airway (LMA) and the laryngeal tube (LT) with the perilaryngeal airway (CobraPLA, PLA) in anaesthetised, paralysed children having brief surgical procedures. After obtaining informed consent, 90 paediatric ASA Status 1 and 2 patients awaiting short surgical procedures were randomised to have their airways managed with an LMA, LT or PLA. Anaesthesia was induced with sevoflurane (2.5 to 4%) and muscle paralysis with mivacurium (0.2 mg/kg intravenously). The number of insertion attempts, time taken to insert the device, haemodynamic responses to insertion (mean arterial blood pressure, heart rate, pulse oximetry and end-tidal CO2), clinical performance and occurrence of postoperative sore throat were recorded. When the airway device was removed, it was examined for visible blood. Patients and parents were asked about the occurrence of sore throat, dysphonia and dysphagia 24 hours postoperatively. Heart rate, mean arterial blood pressure, pulse oximetry and end tidal CO2 did not differ among the groups. Insertion times for the devices were similar (LMA: 19+/-11 seconds, LT 21+/-12 seconds, PLA: 18+/-12 seconds), as were the rates of successful insertion at first attempt (LMA 66.7%; LT 70.0%; PLA 73.3%). The number and type of airway interventions to achieve an effective airway were comparable. When the airways were removed, positive blood traces were noted on 20% of the LMAs, 20% of the PLAs and 10% of the LTs. Haemodynamic, ventilation and oxygenation variables throughout the surgery were similar with LMA, LT and PLA and there were no significant differences in insertion time or signs or symptoms of mucosal trauma when these devices were used in paralysed children.
