Hemodynamic effects of anesthesia type in patients undergoing laparoscopic transabdominal preperitoneal inguinal hernia repair under spinal vs general anesthesia

Purpose General anesthesia has been used as a standard type of anesthesia for laparoscopic inguinal hernia repair by the transabdominal preperitoneal (TAPP) approach, regional anesthesia being occasionally used in high-risk patients. We had previously designed a controlled randomized trial, comparing spinal with general anesthesia in non-high-risk patients undergoing TAPP inguinal hernia repair. Our results suggested that spinal anesthesia offers some advantages in postoperative pain and additional opioid consumption during the early postoperative period. In the context of this trial, hemodynamic effects of each type of anesthesia are presented. Methods Seventy patients, undergoing elective TAPP inguinal hernia repair were randomized to either general or spinal anesthesia. Data regarding patients' hemodynamic status during the procedure under general or spinal anesthesia were collected, measuring systolic blood pressure (SBP), diastolic blood pressure (SBP), mean arterial pressure (MAP) and heart rate (HR). Results There was no significant effect of anesthesia type on systolic, diastolic and mean arterial pressure values after induction of anesthesia and induction of pneumoperitoneum, respectively. There was a significant effect on heart rate values after induction of anesthesia and induction of pneumoperitoneum, respectively. Conclusions Spinal anesthesia is as effective as general anesthesia concerning hemodynamic stability and seems to provide a better result in maintaining hemodynamic stability with fewer fluctuations in blood pressure and mild alterations in heart rate values during TAPP inguinal hernia repair.
