In summary, there are now available very potent narcotics, with small side effect liability. Critical care physicians should be experts in administration of intravenous narcotics and should understand the concepts behind different methods of administration. ⋯ Intravenous administration allows rapid and almost complete control of desired effect. Intravenous access is universally available in the ICU population, and we should take every advantage of it.

This article discusses the roles of the critical care team in providing pain relief. The attitudes of the staff concerning pain relief impact on the delivery of care. ⋯ Nurses have a role in use of epidural administration of narcotics, and provide relief with the use of patient-controlled analgesia and general pain relief measures. Pain as a nursing diagnosis, substance abuse in the medical profession, and control of narcotics are also issues discussed.

Factors related to hospital resource use by intensive care unit (ICU) patients, including severity of illness at admission and intensity of therapy during the first 24 ICU hours were explored in this study. Analysis was based on 2,749 patients admitted to the general medical-surgical ICU at Baystate Medical Center, Springfield, Massachusetts, between February 1, 1983 and January 10, 1985. Resource use was indexed by hospital length of stay (LOS) adjusted for differences between ICU and other hospital days. ⋯ Variability in resource use was analyzed using four diagnosis-related groups (DRGs) accounting for large numbers of ICU patients. The relationship between severity of illness and resource was nonlinear: as severity increased from low levels, resource use increased at a decreasing rate, reached a plateau, and eventually declined. Within each DRG, MPM0 explained a statistically significant percentage of the variability in resource use.

Comparative Study
End-tidal carbon dioxide measurements in critically ill neonates: a comparison of side-stream and mainstream capnometers.
To determine whether end-tidal PCO2 (PETCO2) measurements obtained with two infrared capnometers accurately approximates the arterial PCO2 (PaCO2) in critically ill neonates, simultaneous measurements of PETCO2 were obtained from the distal and proximal ends of the tracheal tube with a sidestream capnometer (Puritan Bennett/Datex--BP/D) and from the proximal end with a mainstream capnometer (Hewlett-Packard-HP) in 20 intubated neonates. Distal sidestream PETCO2 and mainstream PETCO2 correlated with the PaCO2 (r2 = 0.66 and 0.61, respectively) within the range of 26-57 mmHg PaCO2. However, proximal PETCO2 with the sidestream capnometer correlated very poorly (r2 = 0.09) with PaCO2. ⋯ The slope of the regression for the proximal sidestream capnometer did not differ significantly from horizontal. Insertion of the mainstream sensor for the HP capnometer significantly increased the transcutaneous CO2 when compared with preinsertion values. We conclude that both distal sidestream and mainstream capnometry provide accurate estimates of the PaCO2 in critically ill neonates.
