Effect of different ventilation modes on postoperative cognitive dysfunction in elderly patients undergoing laparoscopic abdominal wall herniorrhaphy.
Objective: To compare the effects of three ventilation modes - pressure-controlled ventilation (PC), volume-controlled ventilation (VC), and pressure-regulated volume control ventilation (PRVC) - on postoperative cognitive dysfunction (POCD) in elderly patients undergoing laparoscopic abdominal wall hernia repair.
Methods: In this prospective study, 485 elderly patients undergoing laparoscopic abdominal wall hernia repair were randomly assigned to one of three ventilation groups: PC, VC, or PRVC. Cognitive function was assessed using the Mini-Mental State Examination (MMSE) and the Montreal Cognitive Assessment (MoCA) at baseline (D0), and on postoperative days 1 (D1) and 3 (D3). Intraoperative physiological indicators, including mean arterial pressure (MAP), heart rate (HR), PaCO2, central venous pressure (CVP), dynamic lung compliance (Cdyn), and optic nerve sheath diameter (ONSD), were recorded at five perioperative time points (T1-T5). Plasma concentrations of brain injury biomarkers (Aβ1-40, S-100β) and inflammatory cytokines (IL-1β, IL-6, TNF-α) were measured at baseline and serial postoperative time points (TI-TV).
Results: The incidence of POCD differed significantly among the three ventilation groups on both postoperative day 1 (P = 0.040) and day 3 (P = 0.034). On day 3, post-hoc analysis revealed that the POCD rate in the PRVC group was significantly lower than in the PC group (P < 0.0167). Regarding potential mechanisms, PRVC was associated with improved dynamic lung compliance and a lower optic nerve sheath diameter compared to both PC and VC groups. Furthermore, PRVC significantly reduced plasma concentrations of the inflammatory cytokines IL-1β and IL-6 (all P < 0.05).
Conclusion: In elderly patients undergoing abdominal wall hernia repair, PRVC ventilation reduced the incidence of early POCD, particularly compared to PC ventilation. This neuroprotective effect appears to be linked to improved respiratory mechanics and an attenuated systemic inflammatory response. Therefore, PRVC represents a preferable ventilation strategy for this vulnerable patient population.
期刊介绍：
The International Journal of Clinical and Experimental Pathology (IJCEP, ISSN 1936-2625) is a peer reviewed, open access online journal. It was founded in 2008 by an international group of academic pathologists and scientists who are devoted to the scientific exploration of human disease and the rapid dissemination of original data. Unlike most other open access online journals, IJCEP will keep all the traditional features of paper print that we are all familiar with, such as continuous volume and issue numbers, as well as continuous page numbers to keep our warm feelings towards an academic journal.
