Key result
Applying a laryngeal airway mask significantly decreased postoperative coughing compared with an endotracheal tube in adults under general anesthesia across 15 randomized controlled trials.
Why the study?
Does laryngeal airway mask reduce postoperative coughing compared with endotracheal tube in adults under general anesthesia?
Systematic Review
Does laryngeal airway mask reduce postoperative coughing compared with endotracheal tube in adults under general anesthesia?
Using a laryngeal mask airway instead of an endotracheal tube significantly reduces postoperative coughing in adults undergoing general anesthesia.
Answers are grounded in this paper and cite their sources.
May support preferring laryngeal mask airways to minimize postoperative coughing; confirms pooled benefit across 15 RCTs.
Introduction: Coughing is an airway complication that could affect the outcome of surgery following general anesthesia in adults. In this systematic review, we aimed to study the efficacy of applying laryngeal airway mask (LMA) compared with endotracheal tube (ETT) in reducing the postoperative cough in adults under general anesthesia.Method: PubMed was searched for the relevant articles. Inclusion criteria were all the randomized controlled clinical trials, which used LMA and ETT in adults under general anesthesia. Only English language articles were included in this study with no time limitation.Result: Overall, 15 articles were retrieved, which were relevant with the purpose of this study. Efficacy of LMA in reducing coughing was significantly different with ETT in adults under general anesthesia in various types of surgeries. Calculated number needed to treat (NNT) showed that using LMA would significantly reduce coughing even in one adult patient.Conclusions: Coughing has shown various adverse effects on postoperative main results in some surgeries such as cataract, cranial, etc. Applying LMA could positively decrease postoperative coughing in adults.

Sabzevari et al. (2016) conducted a systematic review in Postoperative cough following general anesthesia. Laryngeal airway mask (LMA) vs. Endotracheal tube (ETT) was evaluated on Postoperative cough. Applying a laryngeal airway mask significantly decreased postoperative coughing compared with an endotracheal tube in adults under general anesthesia across 15 randomized controlled trials.
