Prospective observational study.
Tertiary care teaching hospital.
Adults of either gender with BMI < 40 kg/m2 with end-stage renal failure scheduled to undergo arteriovenous graft or fistula.
The cross-sectional area of the gastric antrum was measured by gastric ultrasound with patient in both supine and right lateral decubitus positions. The volume of the gastric contents were calculated using suitable validated formula. In addition, the nature of the gastric contents was also determined by gastric ultrasound.
The incidence of delayed gastric emptying was found to be 57.7% in the population studied despite following the prescribed preoperative standard fasting guidelines.
There is a high incidence of delayed gastric emptying in patients with end-stage renal failure presenting for surgery which may predispose them to risk of pulmonary aspiration perioperatively.
方法:前瞻性观察性研究。
方法:三级护理教学医院。
方法:BMI<40kg/m2,终末期肾衰竭计划接受动静脉移植或瘘的成人。
■在患者处于仰卧和右侧卧位的情况下,通过胃超声测量胃窦的横截面积。使用合适的验证公式计算胃内容物的体积。此外,胃内容物的性质也通过胃超声确定。
结果:尽管遵循规定的术前标准禁食指南,但在研究人群中发现胃排空延迟的发生率为57.7%。
结论:终末期肾衰竭患者胃排空延迟的发生率很高,因为这可能会使他们在围手术期发生肺抽吸。
