Abstract:
Objective? To determine tourniquet pressure based on limb occlusion pressure(LOP) and to explore its effects on laparoscopic surgery in adults. Methods? Totally 200 adult patients who received laparoscopic surgery in a Class Ⅲ Grade A hospital between June and December 2017 were selected by cluster sampling and divided into the control group (n=100) and the observation group (n=100) according to the random number table. The conventional pressure of 450 mmHg (60 kPa) for lower exterminates was applied to the patients in the control group, while the pressure for the patients in the observation group was determined on limb occlusion pressure with the arterial pulse probe in air pressure tourniquet in accordance with the guideline of the Association of Perioperative Registered Nurses (AORN, 2013) and the care guideline for surgical patients using air pressure tourniquet. The surgical vision score, air pressure tourniquet pressure, color of skin at tourniquet cuff and change of skin morphology were observed and recorded. Results? The clearance of surgical vision of the two groups was 86% and 82%, respectively (P＞ 0.05). The pressure of air pressure tourniquet of the observation group was (316.48±20.10) mmHg, while the fixed pressure of the control group was 450 mmHg (P＜0.05). The incidence of cutaneous injury comorbidities in the control group was 65%, while the incidence of postoperative skin injury in the observation group was 20% (P＜ 0.05). Conclusions? The tourniquet pressure determined based on limb occlusion pressure in laparoscopic surgery for adult patients does not affect the vision of surgeons and can effectively reduce the adverse effects of tourniquet used during operation.
