Educational Case: Hemolysis elevated liver enzymes and low platelets (HELLP syndrome).

Recommended management of patients with preeclampsia starts with a comprehensive clinical maternal and fetal evaluation, including maternal complete blood count, platelets, creatinine, LDH, liver enzymes, and urine test for proteinuria, along with fetal ultrasonographic evaluation and fetal antepartum testing.7 Subsequent management depends on the results of this evaluation and on gestational age. Continued observation is recommended for a woman with a preterm fetus if she has gestational hypertension or preeclampsia without severe features, until delivery at 37 weeks of gestation in the absence of abnormal antepartum testing, preterm labor, premature rupture of membranes, or vaginal bleeding.7 There are numerous conditions precluding such expectant management including severe hypertension refractory to treatment, persistent headaches refractory to treatment, epigastric or right upper pain refractory to treatment, visual disturbances, motor deficit, altered sensorium, stroke, myocardial infarction, new or worsening renal dysfunction, pulmonary edema, suspected acute placental abruption, vaginal bleeding in the absence of placenta previa, eclampsia, or HELLP syndrome.7.

Ventilator-associated pneumonia and intubation location in adults with traumatic injuries: Systematic review and meta-analysis.

BACKGROUND: Ventilator-associated pneumonia (VAP) is an important cause of morbidity and mortality among critically ill patients, particularly those who present with traumatic injuries. This review aims to determine whether patients with traumatic injuries who are intubated in the prehospital setting are at higher risk of developing VAP compared with those intubated in the hospital. METHODS: A systematic review of Medline, Scopus, and Cochrane electronic databases was conducted from inception to January 2021. Inclusion criteria were patients with traumatic injuries who were intubated in the prehospital or hospital settings with VAP as an outcome. Using a random-effects model, the risk of VAP across study arms was compared by calculating a summary relative risk with 95% confidence intervals. The results of individual studies were also summarized qualitatively. RESULTS: The search identified 754 articles of which 6 studies (N = 2,990) met the inclusion criteria. All studies were good quality based on assessment with the Newcastle Ottawa scale. Prehospital intubation demonstrated an increased risk of VAP development in two of the six studies. Among the six studies, the overall quality weighted risk ratio was 1.09 (95% confidence interval, 0.90-1.31). CONCLUSION: Traumatically injured patients who are intubated in the prehospital setting have a similar risk of developing VAP compared with those that are intubated in the hospital setting. LEVEL OF EVIDENCE: Systematic review and meta-analysis; Level IV.

Influence of Critical Care Transport Ventilator Management on Intensive Care Unit Care.

OBJECTIVE: High tidal volume ventilation is associated with ventilator-induced lung injury. Early introduction of lung protective ventilation improves patient outcomes. This study describes ventilator management during critical care transport and the association between transport ventilator settings and ventilator settings in the intensive care unit (ICU). METHODS: This was a retrospective review of mechanically ventilated adult patients transported to an academic medical center via a critical care transport program between January 2018 and April 2019. Ventilator settings during transport were compared with the initial and 6- and 12-hour postadmission ventilator settings. RESULTS: Three hundred eighty patients were identified; 114 (30%) received tidal volumes > 8 mL/kg predicted body weight at the time of transfer. The transport handoff tidal volume strongly correlated with the ICU tidal volume (Pearson r = 0.7). Patients receiving high tidal volumes during transport were more likely to receive high tidal volumes initially upon transfer (relative risk [RR] = 4.6; 95% confidence interval [CI], 3.3-6.5) and at 6 and 12 hours after admission (RR = 2.6; 95% CI, 1.8-3.8 and RR = 2.7; 95% CI, 1.7-4.3, respectively). CONCLUSION: Exposure to high tidal volumes during transport is associated with high tidal volume ventilation in the ICU, even up to 12 hours after admission. This study identifies opportunities for improving patient care through the application of lung protective ventilation strategies during transport.
