To achieve tracheal anesthesia during intubation, an endotracheal tube was purposely designed. The tube had multiple laser-induced perforations in its lower portion produced that allowed administration of the local anesthetic in a pulverized form. We evaluated the efficacy of lidocaine 2% in preventing cough during recovery from general anesthesia. The goal of this study was to perform a topical anesthesia of the hypopharynx, larynx, and trachea. This attenuates the laryngeal reflex occurring during anesthesia recovery and therefore, prevents from potential complications. Sixteen patients ASA I-II underwent surgery with general anesthesia. They were prospectively studied following a randomized double blind protocol. The control group received saline infusion (n = 6) whereas the experimental group (n = 10) was treated with lidocaine. At the end of the anesthesia period, the presence of cough was treated with the test solution. In 90% of cases treated with lidocaine, cough disappeared in about 30 seconds and patients tolerated the endotracheal tube until extubation was performed. All patients who received saline solution presented cough until extubation.

The experience gained with awake tracheal intubation in 39 urgent surgical patients at risk of gastric contents aspiration is presented. After standard premedication fentanyl (4.5 micrograms/kg) was injected, local anesthesia of the root of the tongue, epiglottis and vocal cords was performed with 10% lidocaine spray, rohipnol (0.032 mg/kg) and muscular relaxants were administered and controlled lung ventilation was started. Four patients had vomiting, in 5 patients fentanyl caused muscular restraint. No failures have been observed. Indications for awake tracheal intubation and drawbacks of fentanyl injections are discussed. Awake tracheal intubation prevented effectively aspiration due to retention of coughing and guttural reflexes.

We compared the efficacy of nebulized (N) and sprayed (S) topical anaesthesia prior to fibreoptic bronchoscopy in a blinded study involving 54 patients aged 57 +/- 26 yrs (mean +/- SD). Cough frequency, recorded on cassette tape, was the index of efficacy. All patients received 100 mg lignocaine sprayed into the pharynx, or nebulized in random order prior to bronchoscopy, and all received intravenous diazepam sedation. Each patient received a further 100 mg of lignocaine solution through the bronchoscope onto the vocal cords and major airways during the procedure. No significant difference was found in overall cough frequency between N and S groups (8.7 +/- 6.9 coughs.min-1 N vs 10.5 +/- 6.0 S), and cough frequency was also similar between N and S during the periods above and below the vocal cords. Furthermore, no differences were found in cough frequency between N and S among smokers, patients with asthma and COPD, and patients who had a biopsy procedure, although a trend was seen in all comparisons towards a lower cough frequency with the nebulized route. Most patients in the S group found the spray unpleasant, whereas only one in the N group complained. We conclude that nebulized and sprayed lignocaine have similar efficacy as topical anaesthetics in fibreoptic bronchoscopy, but patient preference favours the nebulized route.

Twenty-eight patients scheduled for lung resection with lateral thoracotomy and postoperative chest drains during combined thoracic epidural bupivacaine plus morphine and general anaesthesia were studied. Postoperative pain treatment was continuous epidural infusion of bupivacaine 0.25% 5 ml h-1 plus morphine 0.2 mg h-1 for 48 h and, in addition, the patients received rectal piroxicam 40 mg randomly and double-blind 12 h and 1 h before surgery and 20 mg 24 h-1 postoperatively or placebo. Pain was evaluated at rest, during cough and mobilisation, together with pulmonary function (FEV1, FVC, PEFR) and sensory level of analgesia repeatedly for 48 h. The results showed efficient pain relief, but without differences in pain scores or need for supplementary analgesics between the two groups. Pulmonary function decreased similarly in the two groups. Thus we were unable to show enhanced analgesia by supplementing an otherwise effective low-dose epidural bupivacaine and morphine treatment with piroxicam after thoracic surgery with chest drains.

Thirty patients, scheduled for short urological surgical procedures and ranked ASA 1 or 2, were randomly assigned to two homogenous groups. In group P, they were given a 2 mg.kg-1 bolus of propofol and 10 micrograms.kg-1 of alfentanil, followed by a continuous infusion of propofol (5 mg.kg-1.h-1) and 5 micrograms.kg-1 doses of alfentanil. In group E, they were given a 0.3 mg.kg-1 bolus of etomidate, followed by an infusion (1.5 mg.kg-1.h-1). The doses of alfentanil were the same as in group P. Further doses of either propofol (0.5 mg.kg-1) or etomidate (0.2 mg.kg-1) were used should anaesthesia prove not to be deep enough. The patients were not intubated, and breathed spontaneously. Surgery lasted a mean of 18.3 +/- 11.8 min (group P) and 18.8 +/- 9.4 min (group E). The following parameters were studied: the amount of each agent required for maintenance of anaesthesia, the duration of apnoea at induction, the quality of anaesthesia and of muscle relaxation, adverse effects (coughing, trismus, restlessness, nausea, vomiting), the time required for recovery, and its quality. In group P, there was a 27% decrease in arterial pressure, without any tachycardia or hypoxia, together with a quick recovery of excellent quality. On the other hand, in group E, there was little or no haemodynamic alteration, but there often was a trismus at induction. Hypoxia also occurred during induction with etomidate, being severe enough in one case to require tracheal intubation and artificial ventilation. The reasons for this hypoxia seemed to be the apnoea and the trismus, which tends to hinder assisted ventilation.(ABSTRACT TRUNCATED AT 250 WORDS)

Sixteen children, aged 2 to 5 years and ranked ASA 1, were included in this study assessing gastro-oesophageal reflux occurring under halothane anaesthesia, before and during, caudal anaesthesia. They were scheduled for surgery below the umbilicus lasting 1 to 5 h. After premedication with oral hydroxyzine (2 mg.kg-1) and intravenous atropine (10 micrograms.kg-1), induction was carried out with 3% halothane. A gastro-oesophageal pH probe was inserted via the nose after calibration at 37 degrees C. A neutral pH for the oesophageal electrode and an acid pH for the gastric one demonstrated the correct position of the probe. The pH was then registered every 4 s. The probe was left in situ until the patient left the recovery room. The caudal anaesthesia catheter was then inserted with the patient lying on his left side. Caudal anaesthesia was began with 2.5 mg.kg-1 of plain bupivacaine and 5 mg.kg-1 of plain lidocaine. When the patient was lying supine again, narcosis was maintained with 0.5% halothane and 50% nitrous oxide. A dose of 1.5 mg.kg-1 of bupivacaine was injected every 30 to 45 min. None of the children displayed any respiratory signs (coughing, dyspnoea, bronchospasm, cyanosis) during the combined anaesthetic. Two episodes of asymptomatic gastro-oesophageal reflux were revealed by this method, one lasting 7 minutes and occurring during insertion of the caudal catheter, and the other, lasting 4 minutes, during recovery. There were no pulmonary sequels. There was excellent respiratory and haemodynamic stability throughout. The two episodes seemed to have been triggered off by rapid displacement of the patient and too deep an anaesthetic.(ABSTRACT TRUNCATED AT 250 WORDS)

Optimum surgical management of the hypopharyngeal diverticulum is controversial. The authors discuss 48 consecutive patients (average age 72.1 years) with documented hypopharyngeal diverticula who were treated by cricopharyngeus myotomy, leaving the diverticula in situ. All came to the hospital with dysphagia; other symptoms included postdeglutitive cough, regurgitation, aspiration, and weight loss. Seven patients had had previous surgery for a Zenker's diverticulum with recurrence. Aspiration pneumonia was treated in 9 patients; 28 patients had concurrent chronic obstructive pulmonary disease or cardiovascular disease. Thirty-nine patients had cricopharyngeus myotomy under local anesthesia, 5 had cricopharyngeus myotomy under general endotracheal anesthesia, and 4 patients underwent myotomy with a cervical esophagostomy. There was one mortality (2.1%) and no incidence of postoperative bleeding, sepsis, or cranial nerve injury. Follow-up was done with 30 patients via telephone an average of 64 months after operation. Twenty-one of 30 patients reported excellent relief of symptoms, 5 reported improvement with occasional symptoms, and 4 patients described persistent dysphagia. Cricopharyngeus myotomy under local anesthetic is a safe and effective approach to the patient with a hypopharyngeal diverticulum. The awake patient can swallow on command, which enables the surgeon to identify the upper esophageal sphincter (UES) and to perform an accurate, complete myotomy. The absence of a pharyngeal suture line eliminates the risk of leakage and mediastinal sepsis, and allows early, postoperative feeding and discharge.

Conventional aerosol techniques were used to determine if inhalation of lidocaine can supplement topical anesthesia applied during bronchoscopy. Aerosols of either saline or lidocaine (50 mg at either 2 or 4% concentrations) were generated by jet nebulizer and administered with or without intermittent positive-pressure breathing. Patients (n = 38) after aerosol inhalation were administered 2% lidocaine (atomized and instilled) for suppression of the gag reflex, control of cough, and airway anesthesia. For five of the patients, prior to bronchoscopy, additional studies with radioaerosols and scintillation scans were accomplished with the same aerosol methodology to demonstrate lung distribution of deposited aerosol. For five patients who received 2% lidocaine aerosol prior to bronchoscopy, the subsequent topical dose of anesthetic required for the procedure was 186 +/- 34 (SEM) mg lidocaine. Nine patients in a control group received saline aerosol and required significantly more anesthetic, i.e., 308 +/- 26 mg; procedures were completed on average within 50 min. The largest difference was in the amount delivered to the upper airway (naris, pharynx, epiglottis, and larynx), i.e., 144 +/- 26 mg for saline control versus 48 +/- 16 mg for lidocaine aerosol protocol. Airways distal to the cords required less anesthesia also, on average, 77 mg for the saline control versus 46 mg for the lidocaine aerosol protocol (p < 0.05). Topical anesthetic dosage data were replicated in 12 additional patients studied by a different bronchoscopist. No additional benefit was afforded by premedication with 4% lidocaine aerosol rather than the 2% aerosol (n = 12). We conclude that aerosol modalities can supplement topical anesthesia during bronchoscopy, primarily by reducing the dose required to anesthetize the upper airway.

A specific entity known as a subglottic hemangioma may present in a six to 12-week-old baby with gradual onset of a two-way stridor. A cough may be present. The voice and feeding may be normal, until severe airway obstruction occurs. A barium swallow with fluoroscopy should be performed by a radiologist or technician experienced with babies to rule out other lesions such as a vascular ring. Direct examination is then performed using a 3.0 mm Storz-Hopkins bronchoscope under general anesthetic as a method of choice. Other methods are discussed. Ideal treatment is probably best undertaken in a large center, using a carbon dioxide laser through a subglottiscope again under general anesthesia with the child breathing spontaneously. Airway support may be necessary at any stage. Alternative treatments are discussed.

A randomized, double-blind study was carried out on 193 ASA I-II surgical patients to assess the effect of aerosolized lidocaine on sore throat, hoarseness and cough in connection with tracheal intubation. The study group received aerosolized lidocaine 100 mg 2 min before tracheal intubation, using a spray. The control group received no spray. The patients underwent a standardized general anaesthesia. The patients were interviewed when leaving the recovery room and the next day in the ward. Specific questions were asked regarding sore throat, cough and hoarseness. There were no significant differences between the two groups, which suggests that topical anaesthesia of the mucosa of the upper airway is ineffective as a means of ameliorating airway complaints in connection with tracheal intubation.
