“…Gastrointestinal ultrasound can provide its anatomical and functional information through the lumen, wall and the surrounding structures of the stomach and bowel. Evaluation of functional processes like peristalsis and blood flow may be used in combination ( Figure 3 ) ( 62 ). Monitoring GI function through gastrointestinal ultrasound may effectively assess acute gastrointestinal injury, predict feeding intolerance and lead to appropriate therapeutic interventions.…”

Point-of-care ultrasonography (POCUS) is performed by a treating clinician at the patient's bedside, provides a acquisition, interpretation, and immediate clinical integration based on ultrasonographic imaging. The use of POCUS is not limited to one specialty, protocol, or organ system. POCUS provides the treating clinician with real-time diagnostic and monitoring information. Visual rounds based on multiorgan POCUS act as an initiative to improve clinical practice in the Intensive Care Unit and are urgently needed as part of routine clinical practice.

Background & aims: Diastolic arterial pressure(DAP) plays a key role in splanchnic perfusion during the development of septic shock. In this trial, we aim to investigate the association between diastolic arterial pressure and gastrointestinal symptoms in sepsis shock patients. Methods: In this retrospective observational study, we extract data from Medical Information Mart for Intensive Care IV by Structured Query Language. Adult patients with sepsis shock were included in the study. We excluded patients with mean arterial pressure(MAP)<65mmHg. Gastrointestinal symptoms were documented every day during the first week after ICU admission. Results: In total, there were 1990 eligible patients in the cohort. During the first week in intensive care unit, three or more gastrointestinal symptoms occurred in 52.8% of the patients. Patients with DAP>=65mmHg were more likely to have a significantly lower incidence of diarrhea (P=0.000 ) and gastrointestinal bleeding(P=0.002) compared to the other two groups. The multivariable analysis also confirmed that DAP>=65mmHg was a protective factor against developing gastrointestinal symptoms(the odds ratio (OR), 0.749; 95% confidence interval (CI), 0.592-0.948; P=0.042). Conclusions：Gastrointestinal symptoms occur frequently in early ICU days, we provide indirect evidence supporting that a further DAP aim of 65mmHg would alleviate gastrointestinal symptoms in individuals with septic shock after a MAP of 65mmHg was reached. DAP should be regarded as a potentially significant hemodynamic target for gastrointestinal perfusion.

PurposeThis study examined whether alterations in Doppler parameters of superior mesenteric artery (SMA) are associated with prolonged mechanical ventilation (PMV) in patients who underwent cardiac valve surgery.MethodsHemodynamic and SMA Doppler parameters were collected at intensive care unit(ICU) admission. The duration of mechanical ventilation was monitored. PMV was defined as mechanical ventilation ≥96 h.ResultsA total of 132 patients admitted to ICU after cardiac valve surgery were evaluated for enrollment, of whom 105 were included. Patients were assigned to the control (n = 63) and PMV (n = 42) groups according to the mechanical ventilation duration. The pulsatility index(SMA-PI) and resistive index of SMA (SMA-RI) were 3.97 ± 0.77 and 0.88 (0.84–0.90) in the PMV group after cardiac valve surgery, which was lower than the SMA-PI (2.95 ± 0.71, p < 0.0001) and SMA-RI of controls (0.8, 0.77–0.88, p < 0.0001). SMA-PI at admission had favorable prognostic significance for PMV (AUC = 0.837, p < 0.0001).ConclusionsAn elevated SMA-PI is common in patients after cardiac valve surgery with PMV. Increased SMA-PI could help predict PMV after cardiac valve surgery. Using point-of-care ultrasound to measure SMA-PI at ICU admission is an acceptable and reproducible method for identifying patients with PMV.
