Vascular Complications of Extracorporeal Membrane Oxygenation: A Systematic Review and Meta-Regression Analysis.

Crit Care Med 2020 12;48(12):e1269-e1277

Cardiothoracic Intensive Care Unit, Department of Cardiothoracic and Vascular Surgery, National University Heart Centre, National University Hospital, Singapore.

Objectives: Perform a systematic review and meta-analysis of vascular complications associated with extracorporeal membrane oxygenation and identify prognostic and predictive factors.

Data Sources: Systematic search for publications reporting vascular complications on extracorporeal membrane oxygenation, published from 1972 to January 31, 2020, was conducted via PubMed, Scopus, and Embase.

Study Selection: Of 4,076 references screened, 47 studies with 6,583 patients were included in final analyses. Studies with fewer than 10 patients were excluded.

Data Extraction: Relevant data, including demographics, comorbidities, extracorporeal membrane oxygenation and cannulation characteristics, occurrence rates of early and late vascular complications, patient outcomes, and use of distal perfusion cannula, were extracted from selected articles into an excel sheet specifically designed for this review.

Data Synthesis: Random-effects meta-analyses and meta-regression analyses were undertaken. Overall pooled estimate of vascular complications in our meta-analysis was 29.5% (95% CI, 23.6-35.9%). Two-thousand three-hundred forty-seven vascular complications in 6,124 venoarterial extracorporeal membrane oxygenation patients compared with 95 in 459 venovenous extracorporeal membrane oxygenation patients (odds ratio, 2.35; 95% CI, 1.87-2.96; p < 0.0001) were analyzed. Successful weaning off extracorporeal membrane oxygenation occurred in 60.6% of pooled patients; 46.2% were eventually discharged. Pooled prevalences of vascular complications like significant bleeding, limb ischemia, and cannula site bleeding were 15.4% (95% CI, 8.6-23.7%), 12.6% (95% CI, 10.0-15.5%), and 12.6% (95% CI, 9.6-18.5%), respectively. Meta-analysis showed that the use of distal perfusion cannula was associated with lower odds of limb ischemia (odds ratio, 1.93; 95% CI, 1.17-2.47; p = 0.03) Meta-regression showed that male sex, smoking, advanced age, and comorbidities contributed to higher in-hospital mortality, while distal perfusion cannula was protective.

Conclusions: Nearly a third of patients on extracorporeal membrane oxygenation develop vascular complications; elderly males with comorbidities appear vulnerable. The use of distal perfusion cannulas caused significant reduction in limb ischemia and mortality.

Cytoreduction with hyperthermic intraperitoneal chemotherapy: An anaesthetic challenge.

Indian J Anaesth 2014 Jan;58(1):59-62

Department of Anesthesiology, Pain and Palliative Care, Cancer Institute, Adyar, Chennai, Tamil Nadu, India.

Cytoreductive surgery combined with hyperthermic intraperitoneal chemotherapy plays a considerable role as a treatment modality in surgical oncology in western countries. The advantage of this procedure is that the heated chemotherapeutic agent is circulated in the abdominal cavity and achieves high peritoneal concentration with limited systemic absorption. This procedure is complex not only to the surgical team, but also to the anaesthetist because apart from managing the usual physiologic changes associated with major surgery, one should also be prepared to manage the physiologic changes during the hyperthermic phase. Here, we present our experience with our first case.
