Sedation and Analgesia in Transportation of Acutely and Critically Ill Patients.

Transportation of acutely or critically ill patients is a challenge for health care providers. Among the difficulties that providers face is the balance between adequate sedation and analgesia for the transportation event and maintaining acceptable respiratory and physiologic parameters of the patient. This article describes common challenges in providing sedation and analgesia during various phases of transport.

A non-lethal chemically based approach to investigate the quality of harbour sediments.

A non-lethal chemically based approach was used to investigate the quality of harbour sediments receiving combined road runoff and sewage effluents. A previous investigation of the behaviour of the amphipod Corophium volutator linked polycyclic aromatic hydrocarbons (PAH) in sediments corresponding to the probable effects levels listed in the sediment quality guidelines of the Canadian Council of the Marine Environment to a sediment avoidance response. Since the amphipods did not biotransform contaminants, bioaccumulation was the only fate pursued to examine the bioavailability of PAH.
