The use of regional anesthesia including paravertebral blocks has been advocated for the treatment of pain from rib fractures in adults. Although paravertebral nerve blocks have been used in pediatric patients to manage postoperative pain for surgeries to the thorax and abdomen, their use for analgesia after rib fractures and thoracic trauma has not been reported. We report the use of a T7 continuous paravertebral nerve block for pain relief in a 5-week-old, 5-kg infant who suffered T7 and T8 rib fractures and a pulmonary contusion to the left chest secondary to a gunshot wound.

Randomized Controlled Trial Multicenter StudyA pilot study for a prospective, randomized, double-blind trial of the influence of anesthetic depth on long-term outcome.
Greater depth of anaesthesia may be associated with a higher incidence of wound infection, mortality and composite risk of complications.

Randomized Controlled TrialDexmedetomidine Reduces Propofol and Remifentanil Requirements During Bispectral Index-Guided Closed-Loop Anesthesia: A Double-Blind, Placebo-Controlled Trial.
The α2-adrenergic agonist dexmedetomidine is a sedative and can be used as an adjunct to anesthetics. Our primary goal was thus to determine the extent to which dexmedetomidine reduces the requirement for propofol and remifentanil. ⋯ Dexmedetomidine administration significantly reduced the requirement for both propofol and remifentanil during anesthetic induction and reduced propofol use during maintenance of anesthesia. Dexmedetomidine also delayed postoperative analgesic use. Dexmedetomidine is a useful adjuvant that reduces anesthetic requirement and provides postoperative analgesia.

Aseptic trauma engages the innate immune response to trigger a neuroinflammatory reaction that results in postoperative cognitive decline. The authors sought to determine whether high-mobility group box 1 protein (HMGB1), an ubiquitous nucleosomal protein, initiates this process through activation and trafficking of circulating bone marrow-derived macrophages to the brain. ⋯ Postoperative neuroinflammation and cognitive decline can be prevented by abrogating the effects of HMGB1. Following the earlier characterization of the resolution of surgery-induced memory decline, the mechanisms of its initiation are now described. Together, these data may be used to preoperatively test the risk to surgical patients for the development of exaggerated and prolonged postoperative memory decline that is reflected in delirium and postoperative cognitive dysfunction, respectively.
