Hypoxemic patients often desaturate further with movement and transport. While inhaled epoprostenol does not improve mortality, improving oxygenation allows for transport of severely hypoxemic patients to tertiary care centers with a related improvement in mortality rates. Extracorporeal membrane oxygenation (ECMO) use is increasing in frequency for patients with refractory hypoxemia, and with increasing regionalization of care, safe transport of hypoxemic patients only becomes more important. In this series, four cases are presented of young patients with severe hypoxemic respiratory failure from Legionnaires’ disease transported on inhaled epoprostenol to ECMO centers for consideration of cannulation. With continued climate changes, Legionella and other pathogens are likely to be a continued threat. As such, optimizing oxygenation to allow for transport should continue to be a priority for critical care transport (CCT) services.
Inter-facility transport of critically ill patients is associated with a high risk of adverse events, and critical care transport (CCT) teams may spend considerable time at sending institutions preparing patients for transport. The effect of mode of transport and distance to be traveled on on-scene times (OSTs) has not been well-described.
Quantification of the time required to package patients and complete CCTs based on mode of transport and distance between facilities is important for hospitals and CCT teams to allocate resources effectively.
This is a retrospective review of OSTs and transport times for patients with hypoxemic respiratory failure transported from October 2009 through December 2012 from sending hospitals to three tertiary care hospitals. Differences among the OSTs and transport times based on the mode of transport (ground, rotor wing, or fixed wing), distance traveled, and intra-hospital pick-up location (emergency department [ED] vs intensive care unit [ICU]) were assessed. Correlations between OSTs and transport times were performed based on mode of transport and distance traveled.
Two hundred thirty-nine charts were identified for review. Mean OST was 42.2 (SD=18.8) minutes, and mean transport time was 35.7 (SD=19.5) minutes. On-scene time was greater than en route time for 147 patients and greater than total trip time for 91. Mean transport distance was 42.2 (SD=35.1) miles. There were no differences in the OST based on mode of transport; however, total transport time was significantly shorter for rotor versus ground, (39.9 [SD=19.9] minutes vs 54.2 [SD=24.7] minutes; P <.001) and for rotor versus fixed wing (84.3 [SD=34.2] minutes; P=0.02). On-scene time in the ED was significantly shorter than the ICU (33.5 [SD=15.7] minutes vs 45.2 [SD=18.8] minutes; P <.001). For all patients, regardless of mode of transportation, there was no correlation between OST and total miles travelled; although, there was a significant correlation between the time en route and distance, as well as total trip time and distance.
In this cohort of critically ill patients with hypoxemic respiratory failure, OST was over 40 minutes and was often longer than the total trip time. On-scene time did not correlate with mode of transport or distance traveled. These data can assist in planning inter-facility transports for both the sending and receiving hospitals, as well as CCT services.
Critical care transport (CCT) teams must manage a wide array of medications before and during transport. Appreciating the medications required for transport impacts formulary development as well as staff education and training.
As there are few data describing the patterns of medication administration, this study quantifies medication administrations and patterns in a series of adult CCTs.
This was a retrospective review of medication administration during CCTs of patients with severe hypoxemic respiratory failure from October 2009 through December 2012 from referring hospitals to three tertiary care hospitals.
Two hundred thirty-nine charts were identified for review. Medications were administered by the CCT team to 98.7% of these patients, with only three patients not receiving any medications from the team. Fifty-nine medications were administered in total with 996 instances of administration. Fifteen drugs were each administered to only one patient. The mean number of medications per patient was 4.2 (SD=1.8) with a mean of 1.9 (SD=1.1) drug infusions per patient.
These results demonstrate that, even within a relatively homogeneous population of patients transferred with hypoxemic respiratory failure, a wide range of medications were administered. The CCT teams frequently initiated, titrated, and discontinued continuous infusions, in addition to providing numerous doses of bolused medications.
