Comparison of the use of laryngeal mask airway Supreme and laryngeal mask airway ProSeal in prone position for pilonidal sinus excision surgery

Abstract

Background Surgeries that require the patient to be in the prone position represent a challenge to the anesthesiologist in terms of securing the airway and additional time and personnel required for induction in the supine position and shifting to the prone position. Use of the classic laryngeal mask airway (LMA) in the prone position is a subject of controversy; the ProSeal LMA may be more suitable as it forms a better seal and provides access to the stomach. LMA Supreme is a newly introduced single-use supraglottic device that shares common features of both the LMA ProSeal and the intubating LMA. Aim of this study The aim of the study was to compare the use of LMA ProSeal and LMA Supreme after induction of anesthesia in the prone position. Patients and methods The study included 80 adult male patients for pilonidal sinus excision surgery. They were randomly divided into two equal groups: group P and group S. The ProSeal was used in group P and the Supreme was used in group S. Ease of insertion, ease of ventilation, leakage of inspiratory gases, SpO ₂ , EtCO ₂ , blood on the airway device after removal, and postoperative incidences of sore throat were recorded. Results There was no statistical difference between the two groups in terms of age, BMI, or duration of surgery. Both devices provided good air seal and good ventilation. Blood-stained saliva and postoperative sore throat were found more with ProSeal use than with Supreme. Conclusion Allowing the patients to take the prone position themselves and then inducing general anesthesia and securing the airway either with ProSeal or with Supreme is a safe practice.
