RESUMO
BACKGROUND AND AIMS: Videolaryngoscopes are crucial components of a difficult airway cart. Issues of cost and availability, however, remain a problem. We compared the combination of an endoscope used in conjunction with the Macintosh laryngoscope with established videolaryngoscopes and the Macintosh laryngoscope using the intubation difficulty scale (IDS) score. MATERIALS AND METHODS: A prospective randomised study including 120 adult patients, American Society of Anaesthesiologists (ASA) physical status I-III, with an anticipated difficult airway scheduled for elective surgery were randomly allocated to one of four groups: Truview EVO2 (group 1), C-MAC D Blade (group 2), videoendoscope (group 3), or Macintosh laryngoscope (group 4). The IDS score was the primary outcome. Secondary outcomes included the Cormack-Lehane grade, time to tracheal intubation, haemodynamic responses, and adverse events. RESULTS: A significant proportion of patients in groups 2 and 3 had an IDS score of zero (73.3 and 70%, respectively). IDS scores were significantly lower in the C-MAC D blade and videoendoscope groups attributable to differences in parameters N4, N5 and N6 [C/L grades, lifting force and laryngeal pressure required] (P < 0.001). The C-MAC D blade and the Macintosh laryngoscope required less time for intubation as compared to the Truview EVO2 and videoendoscope. No differences were noted in post-intubation haemodynamic parameters and other adverse events. CONCLUSION: The performance of videoendoscope was comparable to C-MAC D Blade and superior to Truview EVO2 and Macintosh laryngoscope with respect to the IDS score and may thereby provide an effective alternative to commercial videolaryngoscopes in low resource settings.
RESUMO
Aspiration of foreign body (FB) into the airways is common in children and continues to be a cause for morbidity and mortality. We report herein, successful thoracoscopic management of a child who aspirated a large magnetic FB into his right bronchus and developed a tear of bronchus intermedius (BI) during an attempt at bronchoscopic retrieval using rigid bronchoscope. The impacted FB was successfully removed thoracoscopically followed by thoracoscopic BI repair.
RESUMO
The objective is to evaluate the prophylactic profile, efficacy of granisetron and ondansetron to prevent postoperative nausea and vomiting (PONV) after middle ear surgery. In a randomized, double blind trial, one hundred patients undergoing middle ear surgery received either granisetron 1 mg or ondansetron 8 mg in equal volume (n = 50 for each) intravenously towards the end of surgery and before reversal of anaesthesia. A standard general anaesthetic technique was employed. Postoperatively, during the first 24 h after anaesthesia, the incidence of PONV, recovery score, time to first feeding, willingness to have the same prophylactic antiemetic drug in future and adverse events were recorded. The incidence of vomiting once (PONV score 2) was significantly less, 4% with granisetron and 22% with ondansetron (P = 0.002) respectively and the incidence of vomiting twice or more times in 30 min interval (PONV score 3) was significantly less, 8% with granisetron as compared to 34% with ondansetron (P = 0.001). The requirement of rescue antiemetic drug was significantly higher in ondansetron group, i.e. 34 vs. 8% in granisetron group (P = 0.001). The incidence of adverse events, recovery score and time to first feeding were comparable among the groups. Willingness to have the same prophylactic antiemetic drug in future was significantly high in patients receiving granisetron. Granisetron is more efficacious and desirable drug than ondansetron for reducing the incidence of PONV in patients undergoing middle ear surgery.
