Influence of different tilt positions for laparoscopic hysterectomy on intraocular pressure and postoperative comfort of patients

Abstract

Objective To observe the influence of different tilt positions for laparoscopic hysterectomy on intraocular pressure and patients’ postoperative comfort. Methods Totals of 80 patients with laparoscopic surgery with grade-I anesthesia (American Society of Anesthesiologists, ASA) were chosen and divided into group A(15°T) and group B (30°T) by using the random table methods, with 40 cases in each. Intraocular pressure of patients at baseline (T0), 30 minutes (T1) and 60 minutes (T2) of pneumoperitoneum and after changing the position, and 10 minutes after pneumoperitoneum were monitored. The follow-up of the patients was within 24 hours asking the comfort of them. Results The intraocular pressure of patients at T1 and T2 in group A were (18.16±2.16) and (19.60±2.18)mmHg, which were significantly lower than group B [(19.21±2.17) and (20.87±2.17)mmHg] (t=2.168 9, 2.611 3, respectively; P 0.05). Conclusions 15°head-down position laparoscopic surgery has less effect on the patient’s intraocular pressure than 30°head-down position laparoscopic surgery, besides, patients have more comfort.
