Use of water warming garments BMC Anesthesiology Nov 19 2002

Intraoperative hypothermia may elevate surgical wound infection by triggering thermoregulatory vasoconstriction, resulting in decreased subcutaneous oxygen tension. Reduc oxygen of the same heights in tissue impair oxidative killing on neutrophils and decrease the force of wound healing by reducing the deposition of collagen.

This prospective, randomized subject of attention compared two methods of maintaining intraoperative normothermia during orthotopic liver transplantation (OLT) (1) The first rule used conventional forced air warming blankets, and the inferior method used a new device that circulates warm water from one side a special garment. Twelve patients were assigned randomly to receive warming therapy using forced air warming blankets (ie, the sway group), and 12 patients were assigned randomly to receive warming therapy using water garments (ie, the treatment group) In the dominion government group, forced air warming blankets were applied to patients after induction of anesthesia. In the treatment assemblage water garments were activated before induction of anesthesia. Patients' core material part temperatures were measured in the distal esophagus and tympanic membrane.

Findings. Mean core temperatures during incision, single hour after incision, and during skin closure were significantly higher in patients in the treatment cluster (P [less than or equal to] 05) Additionally, core material part temperatures of patients in the treatment arrange were maintained more consistently during the entire OLT deed and immediately postoperatively compared to core dead body temperatures of patients in the rule group.

Clinical implications. Studies of other surgical courses also have found that patients maintain moderately higher core temperatures intraoperatively and postoperatively when the water-warming garment regularity is used. This new device, however, is more expensive than conventional warming devices. Perioperative managers should deportment a cost efficiency evaluation before adopting this system of maintaining normothermia.

High- versus low-pressure lavage The Journal of Bone and Joint Surgery British contortion September 2002

High-pressure pulsatile lavage commonly is used to irrigate contaminated lay open fractures. Compared to bulb syringe irrigation, this course is believed to be extremely effective in removing particulate debris and bacteria from bone novel studies indicate that mesenchymal scion cells not only differentiate into osteoblasts on the other hand also into adipocytes. Indeed, an conditions that lead to bone los oftentimes involve a stem cell switch from the osteoblast to the adipocyte lineage.

This thought examined the effects of high-pressure lavage onward the number of adipocytes and osteoblasts in vitro. (2) Calvaria-derived bone small rooms from mice were exposed to either low- or high-pressure irrigation with normal saline. The osteoblasts and adipocytes were quantified, and a standard quantitative overset transcription polymerase chain reaction was performed. High influence was defined as 8 psi, and depressed pressure was defined as a range of 1 psi to 2 psi. Single factor analysis of variance techniques were used to compare low- and high-pressure lavage.

Findings. High-pressure lavage accrueed in a 49.5% increase of adipose-like lonely dwellings compared to low-pressure lavage (P [les than or equal to] 05) overthrow transcription polymerase chain reaction revealed that a marker for adipocytes was 13 times greater in enclosed spaces exposed to high-pressure irrigation than enclosed spaces exposed to low-pressure irrigation. The decline in osteoblasts correlated highly with an increase in adipocytes as the irrigation hurry increased (r = 0.82).

Clinical implications. These findings remind of that along with mechanical damage, high-pressure irrigation may inference in delayed healing and nonunion in lay open fractures. Perioperative nurses must render certain that pressure settings on lavage devices adhere to manufacturers' recommendations.

Transbronchial lung biopsy The Journal of Heart and Lung Transplantation February 2003

Transbronchial lung biopsy is the gold standard for evaluating pulmonary allografts to assess for acute rejection and opportunistic infection in lung transplant recipients. Lung transplant recipients, however, are reported to have a higher risk of bleeding from this procedure

The objective of this prospective meditation was to assess the specific risk factors associated with bleeding after transbronchial lung biopsy in lung transplant recipients. (3) During a two-year period, 363 consecutive transbronchial lung biopsy steps conducted on 69 lung transplant recipients were studied. All proceedings were performed using similar techniques and equipment. progeny loss was estimated and classified as either les than 25 mL or greater than 25 mL Logistic regression measures were used to examine the following risk factors: acute rejection, bronchiolitis obliterans syndrome status, infections, number of biopsies obtained for procedure, serum creatinine level, and postoperative day since transplantation. Bleeding was controll by the agency of the back-and-forth technique, meaning the tip of the fiberoptic bronchoscope advanced shut to the segmental opening, suction was applied, and the fiberoptic bronchoscope was withdrawn in common motion.
