The association of capillary refill time and return of spontaneous circulation during out-of-hospital cardiac arrest: an observational study.

ABSTRACT:

Introduction

Microcirculatory alterations are predictive of poor outcomes in patients with shock and after cardiac arrest in animal models. However, microcirculatory alterations during human cardiac arrest have not yet been studied.

Methods

We prospectively included adult patients receiving resuscitation after witnessed out-of-hospital cardiac arrest. Exclusion criteria were hypovolemia, hypo- or hyperthermia (< 34.0 °C, > 37.5 °C), peripheral arterial disease, Raynaud's disease, and logistical issues (e.g., shortage of space). Capillary refill time was measured on the finger (CRT-F) and the earlobe (CRT-E) every other minute until return of spontaneous circulation (any ROSC) or termination of resuscitation. The primary endpoint was any ROSC, secondary endpoints were 30-day-
