The LMA Supreme in 700 parturients undergoing Cesarean delivery: an observational study
Canadian Journal of Anesthesia, 05/08/2012
Yao WY et al. – In a carefully selected group of parturients, the LMA Supreme (SLMA) is a useful alternative to tracheal intubation for Cesarean delivery, providing effective ventilation and a low incidence of side effects or complications.Methods
- Non-obese parturients with at least four hours of fasting and antacid prophylaxis scheduled for uncomplicated Cesarean delivery were recruited from June 2009 through May 2010 at the Quanzhou Women’s and Children’s Hospital, China.
- The authors recorded the number of SLMA insertion attempts, the time to effective ventilation, the incidence of aspiration, and other anesthetic and obstetric outcomes.
- Postoperatively, they noted the presence of blood on the SLMA, postoperative sore throat, and patient satisfaction.
- Analysis included comparison of results between parturients having elective and urgent Cesarean delivery.
- The authors recruited 700 parturients (576 elective, 124 urgent).
- Mean (standard deviation) body mass index was 25.6(2.5)kg.m-2.
- All SLMA insertions were successful, with 686 (98%) inserted on first attempt and a time to effective airway of 19.5(3.9)sec.
- They maintained ventilation and oxygenation in all parturients with a good seal and there was no evidence of aspiration.
- Eighteen parturients (2.6%) had blood on the SLMA upon removal, 24(3.4%) had sore throat, and patient satisfaction was 85(7)%.
- These results were similar in elective and urgent cases.
