Laryngeal Mask Airway in Laparoscopic Hernia Repair

Laryngeal Mask Airway Versus Endotracheal Intubation for Laparoscopic Inguinal Hernia Repair

This prospective randomized study will evaluate the effectiveness of laryngeal mask airway (LMA) versus endotracheal intubation (ETT) for patients undergoing laparoscopic inguinal hernia at CMH.

Study Overview

• Status: Completed
• Conditions: Inguinal Hernia; Inguinal Hernia, Indirect; Inguinal Hernia Unilateral; Inguinal Hernia Bilateral
• Intervention / Treatment: Device: Laryngeal Mask Airway; Device: Endotracheal Tube Device

Detailed Description

This study aims to evaluate the effectiveness during general anesthesia of laryngeal mask airway versus endotracheal tube for laparoscopic inguinal hernia repair. There are limited pediatric literature evaluating the use of laryngeal mask airway for laparoscopic procedures compared with traditional endotracheal intubation. This study aims to add to this literature in providing information comparing the two techniques. The rationale for this study is to show that general anesthesia with laryngeal mask airway is an effective and non-inferior technique compared with general anesthesia with endotracheal intubation in pediatric patients undergoing laparoscopic inguinal hernia repair and may offer benefits in terms of efficiency of care and respiratory complications.

Arms and Interventions

Participant Group / Arm	Intervention / Treatment
Other: Cohort A: Receives Laryngeal Mask Airway Device; In this study arm, after induction of general anesthesia, the patients will receive a laryngeal mask airway device.	Device: Laryngeal Mask Airway; Laryngeal mask airway will be used as an airway device for Cohort A in the standard fashion.
Other: Cohort B: Receives Endotracheal Tube Device; In this arm, after induction of general anesthesia, the patients will receive an endotracheal tube airway device.	Device: Endotracheal Tube Device; Endotracheal tube airway will be used as an airway device for Cohort B in the standard fashion.

What is the study measuring?

Primary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Oxygen Saturation Measured by Pulse Oximetry in Percent Saturation	Oyxgen saturation will be measured by pulse oximetry in percent saturation at three time points during the anesthetic	Patients will have oxygen saturation measured directly after placement airway device, the first oxygen saturation recorded five minutes after the start of surgery, and immediately prior to removal airway device, assessed up to 2 hours.

Secondary Outcome Measures

Outcome Measure	Measure Description	Time Frame
End-tidal Carbon Dioxide Measured by Capnography in mm Hg	Patients will have end-tidal carbon dioxide measured by capnography in mm Hg at three standardized time points during anesthesia.	Patients will have end-tidal carbon dioxide measured directly after placement of device, the first end-tidal carbon dioxide measurement recorded five minutes after the start of surgery, and immediately prior to removal of device, assessed up to 2 hours.
Peak Airway Pressure Will be Measured in cm H2O	Patients will have peak airway pressure in cm H2O measured at three standardized time points during anesthesia.	Patients will have peak airway pressure measured directly after placement airway device, the first airway pressure recorded five minutes after the start of surgery, and immediately prior to removal airway device, assessed up to 2 hours.
Documentation of Laryngospasm Occurrence	Will document if laryngospasm occurs in both groups at any time during the surgery.	Patients will have the occurrence of laryngospasm documented at any time point during the surgery, assessed up to 2 hours.
Documentation of Oxygen Desaturation	Will document if oxygen desaturation occurs at any time during the surgery as defined as an oxygen saturation of less than 90%.	Patients will have the occurrence of oxygen desaturation documented if it occurs at any time point during the surgery, assessed up to 2 hours.
