This study investigated plasma concentration profiles, pharmacokinetic characteristics and side-effects of lidocaine following 3 different administration techniques. Sixty ASA I/II patients undergoing elective ENT-operations were randomised into 4 groups. Lidocaine 1% (1 mg/kg) was administered 50 min before the end of the operation, via a regular endotracheal tube (group 1), a suction-catheter deep endobronchially (group 2), or an EDGAR-(Endobronchial-Drug and Gas Application during Resuscitation)-tube characterized by a separate injection channel ending at the orifice of the tube (group 3). For the control group, a regular endotracheal tube was inserted without lidocaine administration (group 4). Anesthesia was induced with propofol (2 mg/kg), sufentanil (0.5 micrograms/kg), and vecuronium (0.08 mg/kg) and continued as total intravenous anesthesia with propofol (8 mg/kg/h) and oxygen in air (FiO2 = 0.33). A control and 13 blood samples were taken up to 180 min after lidocaine administration. Lidocaine plasma concentrations were determined using a fluorescence polarization immunoassay (TDxFLx). Heart rate, blood pressure, endtidal PcO2, and oxygen saturation were similar in all groups investigated. Ventilation was interrupted for 3.6 +/- 0.5 s in group 1 and 10.2 +/- 0.8 s in group 2, to administer lidocaine. Patients from group 3 were ventilated continuously because of a separate injection channel integrated in the EDGAR-tube. Sore throat was significantly increased in group 2 as compared with groups 1, 3 and 4. Asorption of lidocaine in groups 1-3 resulted in maximal mean plasma concentrations ranging from 0.78 to 0.85 micrograms/ml after 16.9 to 22.4 min.(ABSTRACT TRUNCATED AT 250 WORDS)

The cuff of the laryngeal mask airway (LMA) is highly permeable to nitrous oxide (N2O), and cuff pressure increases during N2O/O2 anaesthesia. The extent of these changes and their effect on LMA position have previously only been investigated for short procedures. The current study was designed to investigate the effects of nitrous oxide-oxygen (N2O/O2) anaesthesia lasting one to two hours on cuff pressure, LMA positioning and pharyngeal morbidity. Twenty-four male patients underwent spontaneous ventilation anaesthesia with 66% N2O in oxygen and isoflurane. Following insertion and inflation of a #4 LMA with 30 ml air, mean (SD) cuff pressures immediately increased from 107 (9) to 145 (12) mmHg and then at a decreasing rate for 90 min to peak at 215 (12) mmHg. There was a correlation between N2O concentration and final cuff volume (P < 0.001). There was no displacement of the LMA cuff in any patient. Three of 19 patients had a mild sore throat. This study demonstrates that the increase in LMA cuff pressure is self limiting over a one-to-two-hour period and does not cause displacement of the LMA. There is no evidence that cuff pressure monitoring and pressure limitation is necessary during LMA anaesthesia.

Four patients showing classic physical stigmata of traumatic asphyxia were studied. Cervicofacial cyanosis and edema, subconjunctival hemorrhage, and multiple ecchymotic hemorrhage of the face, neck, and upper part of the chest were documented. Admission Glasgow coma scale scores ranged from 8 to 15. All but one had no associated injury. Skin discoloration resolved within 3 weeks. Complete resolution of subconjunctival hemorrhage occurred 1 month later. In our series, sore throat, hoarseness, dizziness, numbness, and headaches were common. Profound lower leg pitting edema, hemoptysis, hemotympanum, and transient visual loss were noted. Chest radiographic findings were normal in all patients. Microscopic hematuria was noted in one patient. Diagnosis is made from the history and characteristic appearance of the patient. Treatment is directed to the associated injury. Oxygen supplement with head elevation to 30 degrees is the mainstay of treatment. If the patient survives the initial insult, the prognosis is excellent.

Poliomyelitis is an acute viral disease that attacks the brain and the ventral horn of the spinal cord. Damage to the lower motor neurons usually results in atrophy and weakness of muscle groups, perhaps paralysis and possibly deformity. A second type, bulbar poliomyelitis, infects the medulla oblongata and may result in dysfunction of the swallowing mechanism along with respiratory and circulatory distress. Minor forms of poliomyelitis result in fever, sore throat, headache, and upper body stiffness, but leave no significant atrophy or paralysis. The purpose of this paper is to review post-polio syndrome (PPS) as well as the effect of exercise on the symptoms and morphologic adaptations to PPS and where future research efforts should be directed. The most common features of PPS for over 350,000 afflicted survivors include general fatigue, weakness, and joint/muscle pain. The primary reasons for these symptoms include 1) destruction of the anterior horn cells by the polio virus, leaving fewer motor neurons to induce muscle contraction; 2) unaffected motor unit enlargement by reinnervation through terminal sprouting; and 3) defective transmission at the neuromuscular junction secondary to failure of terminal axonal sprout. Acute responses to resistive exercise suggest significant muscle strength decrements in the knee extensors compared with similar aged people without polio. However, limited training investigation indicates significant strength increases for the knee extensors following at least 6 wk of training. Acute aerobic responses also differ significantly from those observed in aged-matched control subjects. Chronic aerobic responses to limited training studies suggest significant elevations in maximal oxygen uptake.(ABSTRACT TRUNCATED AT 250 WORDS)

Glycopyrrolate is an anticholinergic agent used to dry oral secretions and has been advocated for routine use with transesophageal echocardiography (TEE). To evaluate the safety and efficacy of glycopyrrolate for this unique application, a prospective double-blind placebo-controlled study of glycopyrrolate was performed in 61 patients who were awake while undergoing TEE. Thirty patients were randomized to the standard dose of glycopyrrolate (0.2 mg intravenously), and 31 patients received 1 ml of saline solution as placebo. Intravenous midazolam was used for sedation in all but one patient. Heart rate, electrocardiogram, blood pressure, and oxygen saturation were continuously monitored before, during, and after TEE. The patients scored their comfort immediately after TEE and were interviewed at 24 hours for side effects. The operator scored the ease of performing the TEE. No complications occurred in either group. Changes in vital signs and oxygen saturation were similar in both groups. The operator ease and patient comfort was similar in both groups. A significantly higher incidence of the following side effects was observed at 24 hours in patients who received glycopyrrolate versus those who received placebo: sore throat, 63% versus 19%; dry mouth, 43% versus 6%; and urinary retention, 16% versus 0% (p < 0.05 for all). No benefit from glycopyrrolate was noted in operator ease or patient comfort. In conclusion, glycopyrrolate is not recommended for routine use when performing TEE on patients who are awake.

A constant pressure differential valve for the control of tracheal tube cuff pressure was tested under clinical conditions. Fifty-one patients underwent controlled ventilation and 20 patients were allowed to breathe spontaneously. Nitrous oxide 66% with oxygen 33% and halothane were used via a circle system. With controlled respiration at a fresh gas flow of 3-10 l.min-1, the expiratory cuff pressures of 10.1-16 cmH2O and the inspiratory cuff pressures of 23.4-32.4 cmH2O were below venous and arterial mucosal capillary perfusion pressures respectively. Cuff pressures were unaltered with time. Methylene blue instilled into the larynx did not appear in the trachea. Fifty-two control patients had the same incidence of sore throat (40%) and hoarseness (30%) at 24 h. With spontaneous ventilation, fresh gas flows of 5-15 l.min-1 maintained the cuff pressure above 10 cmH2O. We conclude that this valve prevents excessive tracheal cuff pressure while maintaining the airway seal.

A meta-analysis was performed on randomised prospective trials comparing the laryngeal mask airway (LMA) with other forms of airway management to determine if the LMA offered any advantages over the tracheal tube (TT) or facemask (FM). Of the 858 LMA publications identified to December 1994, 52 met the criteria for the analysis. Thirty-two different issues were tested using Fisher's method for combining the P values. The LMA has 13 advantages over the TT and four over the FM. The LMA had two disadvantages over the TT and one over the FM. There were 12 issues where neither device had an advantage. Advantages over the TT included: increased speed and ease of placement by inexperienced personnel; increased speed of placement by anaesthetists; improved haemodynamic stability at induction and during emergence; minimal increase in intraocular pressure following insertion; reduced anaesthetic requirements for airway tolerance; lower frequency of coughing during emergence; improved oxygen saturation during emergence; and lower incidence of sore throat in adults. Advantages over the FM included: easier placement by inexperienced personnel; improved oxygen saturation; less hand fatigue; and improved operating conditions during minor paediatric otological surgery. Disadvantages over the TT were lower seal pressures and a higher frequency of gastric insufflation. The only disadvantage compared with the FM was that oesophageal reflux was more likely. The importance of these findings in terms of patient outcome could not be determined from the published data.

The intubating laryngeal mask airway is a new device that facilitates intubation of the trachea. We assessed its use in 15 awake patients in whom we anticipated difficulty with tracheal intubation; we would otherwise have secured the patients' airways using a fibreoptic bronchoscope. All patients were sedated and had their airways anaesthetised with local anaesthetic. The tracheas of all 15 patients were successfully intubated. The mean time from start of sedation to successful intubation was 10.8 min. The mean time from completion of sedation and airway local anaesthesia to tracheal intubation was 2.8 min. Patients remained haemodynamically stable throughout, peripheral oxygen saturation was maintained and there were no obvious cases of pulmonary aspiration. Most patients complained of sore throat and hoarseness. We have demonstrated through this descriptive study that the intubating laryngel mask airway may, in certain circumstances, be used as an alternative to the fibreoptic bronchoscope.

The cuffed oropharyngeal airway is a modified Guedel airway with a distal inflatable cuff and a proximal connector for attachment to an anaesthesia circuit. The purpose of this study was to evaluate this device for spontaneous ventilation anaesthesia in 100 adult patients. Anaesthesia was induced with fentanyl and propofol and maintained with nitrous oxide and isoflurane in oxygen. The device was inserted when anaesthetic depth was judged to be adequate. Adverse airway events and interventions (i.e., manoeuvres performed in order to provide a clear airway) were analysed from video recordings and detailed notes. The position of the device was assessed fibreoptically during spontaneous ventilation. The device provided a clear airway in 98% of patients during manually assisted ventilation, in 100% during spontaneous ventilation and in 100% during emergence. However, 91% of patients required at least one airway intervention at some time. Jaw life was required for 33% of the time during manually assisted ventilation and 21% of the time during spontaneous ventilation. Most interventions occurred during the first 3 min of either manually assisted or spontaneous ventilation. The incidence of adverse airway events during manually assisted ventilation was 8%, during spontaneous ventilation was 5% and during emergence was 5%. Oxygen saturation briefly fell to between 87 and 89% on six occasions. On fibreoptic assessment, the vocal cords were visible in 29% of patients on fibreoptic assessment and the epiglottis was visible in 90%. Mild sore throat occurred in 4% of patient. We conclude that the cuffed oropharyngeal airway is suitable for spontaneous ventilation anaesthesia and has a low complication rate but that most patients require one or more interventions to provide a clear airway.

A 54-y-o woman presented to the Emergency Department with shortness of breath and sore throat after intranasal administration of Ecbalium elaterium as a folk remedy for her sinusitis. The patient's history included nasal aspiration of the juice of the squirting cucumber (Ecbalium elaterium) for acute maxillary sinusitis. An airway obstruction due to severe uvular angioedema was detected and confirmed by airway X-ray. The patient was treated with 100% oxygen with mask, 0.3 mg epinephrine s.c., and 80 mg prednisolone i.v. Renal and hepatic function tests were normal. After a 24-h observation, the patient was discharged in her previous state of health.
