- Brief 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.

Group Intervention Description group S Spinal Anesthesia for Anorectal Surgeries in Prone Position Patients in group S had spinal anesthesia in the sitting position under complete aseptic technique through a standard mid-line approach. 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. group L General Anesthesia Using Laryngeal Mask Airway for Anorectal Surgeries in Prone Position Patients in group L received standard general anesthesia. Proper (weight-based) classic laryngeal mask airway was then blindly inserted.
- Primary Outcome Measures
Name Time Method comparison was between the induction and emergence anesthesia times needed in each technique 4 months In this group (L) the investigators defined induction time (T1) as the time from completion of initial monitoring until the patient is positioned prone. Emergence time (T2) was defined as the time from the end of surgical dressing till the removal of LMA in the supine position and the patient is ready for transfer to PACU.
