The degree of plicature generates an increase in intraabdominal pressure that causes an increase in intrathoracic pressure. Pressure, volume, flow, and respiratory rate are components of a unique physical variable, the mechanical power (MP), and is an integrated variable linked to most factors related to postoperative pulmonary complications. Purpose: To assess the effect of rectus plication (RP) during abdominoplasty on lung pressures and the contribution to increasing the MP. Method: A open-label study was conducted at TJ Plast Advanced Center for Plastic Surgery in Tijuana, México, from September 2021 to May 2022. The study included forty-six female patients subjected to abdominoplasty or liposuction with abdominoplasty. After the induction of general anesthesia and neuromuscular blockade, they were allocated into two groups: Group 1 pressure control ventilation-volume guaranteed (PCV-VG) and Group 2 volume control ventilation (VCV). Respiratory pressures and MP were assessed before and after RP. Results: During VCV, patients had a greater increase in peak pressure (PIP) (P 0.000). Plateau pressure (P<sub>plat</sub>) increased 1.78 ± 0.35 cmH<sub>2</sub>O in group 2 after RP (P = 0.001). MP had a greater increase in group 2 after RP (P 0.01). Conclusion: This prospective study showed that RP is related to an increase in PIP and P<sub>plat</sub> and an increase in the MP better controlled with PCV-VG ventilation.展开更多
目的:研究了PCV-VG和VCV模式用于老年患者腹腔镜腹部手术的术中氧合功能及创伤程度。方法:选择60例接受腹腔镜腹部手术的老年患者进行研究,随机分为两组,A组按照VCV序贯PCV-VG模式进行通气,B组按照PCV-VG序贯VCV模式进行通气,气腹开始前...目的:研究了PCV-VG和VCV模式用于老年患者腹腔镜腹部手术的术中氧合功能及创伤程度。方法:选择60例接受腹腔镜腹部手术的老年患者进行研究,随机分为两组,A组按照VCV序贯PCV-VG模式进行通气,B组按照PCV-VG序贯VCV模式进行通气,气腹开始前(T0)、气腹开始后第一种通气模式开始后1h(T_1)、切换通气模式通气后1h(T_2),气腹结束后(T_3)分别测定呼吸功能参数、动脉血气参数以及血清损伤指标。结果:T_1时间点处,A组患者的P_(peak)、P_(mean)、P_(plant)均显著高于B组,PaO_2显著低于B组,SpO_2、PaCO_2与B组无显著性差异;T_2和T_3时间点处,A组的P_(peak)、P_(mean)、Pp la n t均显著低于B组,PaO_2显著低于B组,SpO_2、PaCO_2与B组无显著性差异。T_1时间点处,A组的血清sRAGE、KL-6、TNF-α、MDA含量显著高于B组;T_3时间点处,A组的血清sRAGE、KL-6、TNF-α、MDA含量显著低于B组。结论:PCV-VG模式用于老年患者腹腔镜腹部手术能够降低气道压力、改善肺顺应性以及肺泡氧化、减轻肺损伤以及全身创伤。展开更多
