Adverse events following surgical operations are common complications due to removal of tracheal tube in contrast to the tracheal intubation. Awareness about the new methods and strategies for tracheal tube extubation is necessary for a safe and successful extubation. Therefore, we aimed to assess the safety and efficacy of laryngeal mask airway (LMA), streamlined liner of the pharyngeal airway (SLIPA) and I-gel in extubation time of tracheal tube. A one-single randomized clinical trial was conducted in 105 eligible patients in three groups including LMA, SLIPA and I-gel. The patients were under surgery after general anesthesia with propofol (2–3 mg/kg) and fentanyl (1–2 μg/kg). Hemodynamic responses and extubation consequences including coughing rate, laryngospasm, airway obstruction, apnea, breath holding and straining of patients, vomiting, and need for re-intubation were recorded every 5 minutes since inserting of supraglottic airway devices (SADs) until patients restore consciousness. Analysis of data was conducted in SPSS software by analysis of variance (ANOVA) and ANOVA for repeated measurements tests. The overall successful insertion was 100% for LMA and I-Gel and this rate was 97.1% for SLIPA method. A significant decrease was observed in trend of hemodynamic responses in all three groups. Nevertheless, the MBP was lower in LMA group and lower HR was observed in I-Gel and higher HR occurred in SLIPA (P < 0.05). Three groups was same statistically regarding sore throat, vomiting, coughing, breath holding, apnea, laryngospasm, and re-intubation need (P > 0.05). However, the incidence rate of apnea, and laryngospasm, as well as re-intubation need in SLIPA group was 2.9%, respectively. LMA, I-GEL and SLIPA could be considered as useful and safe devices for ventilation control after tracheal tube removal at the end of operation. Three devices were same regarding to sore throat, vomiting, coughing, and breath holding. However, LMA showed lower side effects while SLIPA was related to more occurrences of apnea, laryngospasm, and re-intubation need.
