Recurrence after laparoscopic ventral hernia repair: a prospective pilot study of suture versus tack fixation.
Mesh fixation in laparoscopic ventral hernia repair requires the use of tacks and/or permanent transabdominal sutures. Sutures pass through all fascial and muscle layers of the anterior abdominal wall, whereas tacks secure the mesh simply to peritoneum. Controversy exists regarding the optimal fixation method. ⋯ In multivariate analyses, fixation method did not significantly affect recurrence. In this pilot study, patients undergoing laparoscopic ventral hernia repair with primarily transabdominal sutures or tacks experienced similar recurrence rates. Future studies will be needed to validate these findings.

Few diagnostic modalities in medicine have been the subject of greater debate for as long after their inception as the pulmonary artery catheter. Placement of a Swan-Ganz catheter is associated with various complications, one of which is knotting. ⋯ The case reported is a rare case of Swan-Ganz catheter knotting resulting from inserting an excessive length of Swan-Ganz catheter into the heart. Knotting can be prevented by following the principle rule in floating Swan-Ganz catheters by correlating the inserted length of pulmonary artery catheter (PAC) with the expected change in waveform.

Are adrenal injuries predictive of adrenal insufficiency in patients sustaining blunt trauma?
Adrenal insufficiency (AI) is an uncommon life-threatening development in trauma patients. The aim of this study was to determine if adrenal injury sustained during blunt trauma is associated with an increased risk of AI. A single-institution retrospective cohort review was performed over a 3-year period on all patients with blunt trauma requiring intensive care admission and mechanical ventilation for longer than 24 hours. ⋯ Adrenal injury was not an independent predictor of AI (P = 0.12). After controlling for age and ISS, adrenal injury was not an independent predictor of the development of AI. Adrenal insufficiency should be considered with increasing injury severity and age in the intensive care setting after blunt trauma.

Resuscitation of hypotensive head-injured patients: is hypertonic saline the answer?
Hypertonic saline (HTS) may decrease intracranial pressure (ICP) in severe traumatic brain injury (STBI) and effectively resuscitates hypotensive patients. No data exist on institutional standardization of HTS for hypotensive patients with STBI. It remains unclear how HTS affects brain tissue oxygenation (PbtO2) in STBI. ⋯ Institutional use of HTS in STBI can be safely implemented in a center caring for neurotrauma patients. HTS infusion in hypotensive STBI reduces ICP and raises CPP. Brain tissue oxygenation tends to improve after HTS infusion.

Blast injury in a civilian trauma setting is associated with a delay in diagnosis of traumatic brain injury.
High-pressure waves (blast) account for the majority of combat injuries and are becoming increasingly common in terrorist attacks. To our knowledge, there are no data evaluating the epidemiology of blast injury in a domestic nonterrorist setting. Data were analyzed retrospectively on patients admitted with any type of blast injury over a 10-year period at a busy urban trauma center. ⋯ Blast injury is a complicated disease process, which may evolve over time, particularly with TBI. The missed injury rate for TBI in patients with a Glasgow Coma Scale score of 15 was 36 per cent. More studies are needed in the area of blast injury to better understand this disease process.
