[Serious pulmonary barotrauma in a child after first-time scuba dive].

Scuba diving is increasingly popular for children. However, this activity, including in shallow water, can be responsible for severe accidents. We report the case of a 13-year-old boy who dove for the first time in the Mediterranean Sea and suffered pulmonary barotraumas, complicated by arterial gas embolism with pneumomediastinum, cerebral, and coronary injuries.

Analgesic properties of calcium phosphate apatite loaded with bupivacaine on postoperative pain.

Synthetic calcium-deficient apatites (CDA) are structurally similar to biological apatites and are well known as chemical precursors of biphasic calcium phosphates (BCP). BCP are mixtures of hydroxyapatite and beta-tricalcium phosphate and are widely used as bone substitutes in human surgery. Bupivacaine, a local anesthetic, has been loaded onto CDA using isostatic compaction.

Comparison of fentanyl and sufentanil in combination with bupivacaine for patient-controlled epidural analgesia during labor.

Study Objectives: To compare the efficacy of fentanyl plus bupivacaine with sufentanil plus bupivacaine for treatment of pain during labor and delivery using patient-controlled epidural analgesia (PCEA).

Design: Prospective, double-blind, clinical investigation.

Settings: University-affiliated hospital.
