Exposure to the undersea environment has unique effects on normal physiology and can result in unique disorders that require an understanding of the effects of pressure and inert gas supersaturation on organ function and knowledge of the appropriate therapies, which can include recompression in a hyperbaric chamber. The effects of Boyle's law result in changes in volume of gas-containing spaces when exposed to the increased pressure underwater. These effects can cause middle ear and sinus injury and lung barotrauma due to lung overexpansion during ascent from depth. ⋯ Usual therapy is recompression in a hyperbaric chamber following well-established protocols. Many recreational diving candidates seek medical clearance for diving, and healthcare providers must be knowledgeable of the environmental exposure and its effects on physiologic function to properly assess individuals for fitness to dive. This review provides a basis for understanding the diving environment and its accompanying disorders and provides a basis for assessment of fitness for diving.

Does midazolam enhance pain control in prehospital management of traumatic severe pain?
Midazolam comedication with morphine is a routine practice in pre and postoperative patients but has not been evaluated in prehospital setting. We aimed to evaluate the comedication effect of midazolam in the prehospital traumatic adults. ⋯ According to our study, midazolam does not enhance pain control as an adjunctive to morphine regimen in the management of trauma-induced pain in prehospital setting. However, such midazolam use seems to be associated with an increase in drowsiness.

Death or Neurologic Injury After Tonsillectomy in Children with a Focus on Obstructive Sleep Apnea: Houston, We Have a Problem!
Obesity is epidemic in the United States and with it comes an increased incidence of obstructive sleep apnea (OSA). Evidence regarding opioid sensitivity as well as recent descriptions of deaths after tonsillectomy prompted a survey of all members of the Society for Pediatric Anesthesia regarding adverse events in children undergoing tonsillectomy. ⋯ Deaths or neurologic injury after tonsillectomy due to apparent apnea in children suggest that at least 16 children could have been rescued had respiratory monitoring been continued throughout first- and second-stage recovery, as well as on the ward during the first postoperative night. A validated pediatric-specific risk assessment scoring system is needed to assist with identifying children at risk for OSA who are not appropriate to be cared for on an outpatient basis.

Cranial computed tomography (CT) is generally regarded as the standard for evaluation of structural brain injury in patients with traumatic brain injury (TBI) presenting to the emergency department (ED). However, the subjective nature of the visual interpretations of CT scans and the qualitative nature of reporting may lead to poor interrater reliability. This is significant because CT positive scans include a continuum of structural injury with differences in treatment. ⋯ However, when interrater agreement was assessed with respect to the specific classification of the injury, agreement was poor, with a κ of 0.3 (0.29-0.316; confidence interval [CI] 95%). When classification was collapsed, considering only the presence or absence of hematomas, agreement among all 3 adjudicators improved to 55%, but the κ of 0.355, (0.332-0.78; CI 95%) was still only fair. The data suggest the need for improved recognition and quantification of specific structural injuries in the TBI population for better identification of patients requiring clinical intervention.
