Summary

Anorectal surgeries are of the commonest elective surgeries that are performed worldwide under different types of anaesthesia. The aim of this prospective interventional study was to compare the use of general anaesthesia (GA) using a laryngeal mask airway (LMA) with spinal anesthesia (SA) in anorectal surgeries.

Detailed description

Anorectal surgeries are of the most frequently performed procedures worldwide. These procedures are commonly performed in prone position as it offers sufficient exposure and provides enough surgical space. Choosing the suitable anesthetic technique will help in reducing perioperative complications in patients undergoing surgical procedures in prone position, by taking into consideration changes in cardiovascular and pulmonary physiology, airway management, and proper positioning for the prevention of direct and indirect pressure injuries. The aim of this prospective interventional controlled study was to compare the use of general anesthesia (GA) using a laryngeal mask airway (LMA) with spinal anesthesia (SA) in anorectal surgeries.

Interventions

Type	Name	Description
PROCEDURE	Spinal Anesthesia for Anorectal Surgeries in Prone Position	Spinal anesthesia in sitting position was done under complete aseptic technique through a standard midline approach. One and a half millilitres of 0.5% bupivacaine (7.5 mg) was injected through a 25 Gauge pencil-point needle into the subarachnoid space at L3-L4 or L4-L5 interspace. All patients were kept in a head-up position for 3 minutes. The patient was then asked to turn him- or herself into the prone position on the surgical table with the help of the surgical and anesthetic teams.
PROCEDURE	General Anesthesia Using Laryngeal Mask Airway for Anorectal Surgeries in Prone Position	General anesthesia was induced using fentanyl 2 mcg/kg and Propofol 2-3 mg/kg. Any stomach contents were then suctioned through an oro-gastric tube to reduce the risk of regurgitation. Proper (weight-based) classic laryngeal mask airway was then blindly inserted. laryngeal mask airway was then properly fixed to the face and anesthesia was maintained with isoflurane 1-2% in 50% Oxygen/air mixture.
