A preinstalled nasopharyngeal airway in the right nasal passageway to facilitate nasogastric intubation in anesthetized and intubated patients: a prospective randomized controlled trial.

ABSTRACT: BACKGROUND:Nasogastric intubation (NGI) is usually challenging in patients under general anesthesia, with reported success rate at the first attempt to be less than 50%. The aim of this study was to investigate whether a preinstalled nasopharyngeal airway (NPA) in the right nasal passageway can facilitate NGI in anesthetized and intubated patients. METHODS:A prospective randomized controlled trial including 108 patients scheduled for elective intra-abdominal surgeries requiring a nasogastric tube (NGT) was conducted. Fifty-three patients were randomized to receive NGI through a preinstalled NPA in the right nasal passageway (Group NPA) and 55 patients to receive NGI via the right nostril (Group O). The primary outcomes were success rates of NGI at first attempt, success rates of NGI in accumulative attempts, durations of successful NGI at the first attempt and success rates of NGI for the rescuing methods. The secondary outcomes were bleeding incidence and hemodynamic changes induced by NGI. RESULTS:Success rate of NGI at the first attempt was 83.0% in Group NPA compared with 47.3% in Group O [P?

Project description:Background:Several studies have identified side effects of general anesthesia with endotracheal intubation, such as laryngeal pain, dysphonia, and postoperative nausea and vomiting (PONV). The laryngeal mask airway (LMAw) is believed to decrease these side effects. The aim of this trial was to compare postoperative discomfort, emergence delirium, and recovery time of patients who received either an LMAw or nasotracheal intubation (NTI). Patients and methods:A total of 70 children were randomly assigned to the LMAw group (n=35) or the NTI group (n=35). Both groups underwent mask induction with 8% sevoflurane. The NTI group received muscle relaxant, whereas the LMAw group did not. Postoperative laryngeal pain, dental pain, dysphonia, and PONV were assessed immediately and at 1 hour and 6 hours postoperatively. The Wong-Baker Faces Scale was used to evaluate the patients' self-reported pain. In addition, decayed, missing, and filled teeth (dft/DMFT) values, dental procedure type, number of dental procedures, duration of the dental operation, duration of anesthesia, recovery time, emergence delirium, pediatric dentist's access to the mouth, and parents' satisfaction levels were recorded. Data were analyzed using descriptive statistics, chi-square tests, and two-sample t-tests. Results:The incidence of postoperative laryngeal pain was significantly higher in the NTI group immediately (97.2% vs. 8.5%, P=0.00), 1 hour (94.2% vs. 0%, P=0.00), and 6 hours postoperatively (25.7% vs. 0%, P=0.00). There were no statistically significant differences between the two groups in dental pain scores, dft/DMFT values, duration of anesthesia, duration of the dental operation, number of dental procedures, the incidence of PONV, or pediatric dentist's access to the mouth (P>0.05). Emergence delirium and recovery time were significantly higher in the NTI group (P<0.05). Conclusion:The LMAw provided a more comfortable postoperative period than NTI for children who underwent full-mouth dental rehabilitation under general anesthesia.
