This study aims to compare the effects of a laryngeal mask airway (i-gel) and an endotracheal tube on perioperative hypothermia in patients undergoing laparoscopic inguinal hernia surgery. The primary outcome is the incidence of hypothermia, defined as a core body temperature below 36°C, at the end of surgery. The study will also evaluate perioperative temperature changes and relevant postoperative outcomes between the two airway management groups.
Perioperative hypothermia is a common concern during general anesthesia and surgery. Maintaining normothermia is important for patient safety and postoperative recovery. Airway management techniques may be associated with differences in perioperative heat loss; however, their effects on body temperature in patients undergoing laparoscopic inguinal hernia surgery require further investigation.
This study is designed to compare the effects of a laryngeal mask airway (i-gel) and an endotracheal tube on perioperative hypothermia in patients undergoing laparoscopic inguinal hernia surgery under general anesthesia.
Eligible patients will be allocated to one of two groups according to the airway management technique: the i-gel group or the endotracheal tube group. Perioperative body temperature will be monitored, and the incidence of hypothermia, defined as a core body temperature below 36°C at the end of surgery, will be assessed as the primary outcome.
Additional perioperative and postoperative outcomes, including changes in body temperature and the occurrence and severity of shivering, will be evaluated and compared between the groups.
The findings may help clarify whether the choice of airway management device is associated with differences in perioperative temperature regulation in patients undergoing laparoscopic inguinal hernia surgery.

Exclusion Criteria:
Patients will undergo general anesthesia with an i-gel supraglottic airway device for airway management during laparoscopic inguinal hernia surgery. Perioperative body temperature will be monitored, and the incidence of hypothermia will be assessed.
Device: i-gel Supraglottic Airway Device
Patients will undergo general anesthesia with an endotracheal tube for airway management during laparoscopic inguinal hernia surgery. Perioperative body temperature will be monitored, and the incidence of hypothermia will be assessed.
Device: Endotracheal Tube
Use of an i-gel supraglottic airway device for airway management during general anesthesia in laparoscopic inguinal hernia surgery.
Use of an endotracheal tube for airway management during general anesthesia in laparoscopic inguinal hernia surgery.
Incidence of Perioperative Hypothermia at the End of Surgery
The proportion of patients with a core body temperature below 36°C at the end of surgery will be compared between the i-gel and endotracheal tube groups.
Time frame: At the end of surgery
Change in Core Body Temperature During Surgery
Perioperative changes in core body temperature will be compared between the i-gel and endotracheal tube groups.
Time frame: From the beginning to the end of surgery
Incidence and Severity of Postoperative Shivering
The incidence and severity of postoperative shivering will be assessed and compared between the two groups. Shivering severity will be graded as none, mild, moderate, or severe.
Time frame: During the postoperative period
