Postinduction hypotension (PIH) is closely associated with postoperative adverse outcomes. Preoperative hypovolemia a key risk factor, and many parameters are available from ultrasound to detect hypovolemia, but the accuracy of PIH remains unclear. This systematic review meta-analysis aimed evaluate commonly used measurements predict PIH. We searched PubMed, Cochrane Library, Embase, CNKI, Web Science databases their inception December 2023. Thirty-six studies were included for quantitative analysis. The pooled sensitivities inferior vena cava collapsibility index (IVC-CI), maximum diameter (DIVCmax), minimum (DIVCmin), carotid artery corrected flow time (FTc) 0.73 (95% CI = 0.65, 0.79), 0.66 0.54, 0.77), 0.74 0.60, 0.85), 0.81 0.72, 0.88). specificities IVC-CI, DIVCmax, DIVCmin, FTc 0.82 0.75, 0.87), 0.75 0.66, 0.82), 0.76 0.84), 0.87 0.77, 0.93).

Background: In critically ill patients, the fluid resuscitation is crucial and first step in treatment protocol. Invasive CVP measurement was used to guide resuscitation. However, it time consuming invasive maneuver. Ultrasound of inferior vena cave common carotid arteries are suggest predict response as well or even better. The current work designed compare cava diameter artery with central venous pressure for estimation intravascular volume status septic shock. Patients Methods: study included 60 subjects shock who received vasopressor support. ultrasound were performed before after challenge test. Values documented compared values. This full clinical assessment by detailed examination laboratory workup. Results: MAP significantly increased HR decreased than procedure. addition, CVP, (inferior cava), ICVmax, ICV min (CCAD) increased, IVC CI (%) reduced procedure basal There significant decrease IVCmax, IVCmin CCAD while there increase CI% lower (<8) higher (> 8) positively correlated CCAD, inversely CI%. AUC over 0.75 prediction 0.7 These data reflected better predictive power CCAD. best cutoff value 1.35, 1.25, 10.45 4.15 IVCmin, successively. Conclusion: CCA diameters US may replace patients.

Depending on the total amount of fluid, changes occur in fluid peripheral area. The aim this study was to observe differences caused by hemodynamic after lateral sagittal infraclavicular block (LS-ICB) according inferior vena cava collapsibility index (VCI-CI). In prospective, observational (Clinical Trial Number: NCT05968105), patients undergoing elective hand and wrist surgery with LS-ICB were classified VCI-CI, Group 1 defined as (VCI) diameter < 1.5 cm VCI-CI > 50% 2 VCI 50%. Groups compared for demographic characteristics, durations, rescue analgesics, complications. Continuous parameters pulsed wave Doppler evaluated within groups. Demographic characteristics time periods comparable between Hemodynamic measurements showed no significant differences. However, while remained consistent, exhibited axillary artery diastolic contractility index. A statistical difference observed perfusion at 30 minutes postoperatively, whereas consistent. dosage number requiring analgesics similar across both groups, complications reported. Blood flow increased without a corresponding increase diameter. tendency toward lower postoperative period.
