Accuracy and precision evaluation of Thai plastic microhematocrit tubes: the first product from Thailand.

Background: In Thailand, the spun microhematocrit method is usually performed using glass microhematocrit tubes even though broken glass tube during use may result in a risk of injury and blood-borne infection. The main reason is that the safer product alternatives such as plastic microhematocrit tubes are more expensive. Now, plastic tubes for hematocrit determination can be produced in Thailand at a much cheaper price.

Obesity, epidural analgesia, and subcostal incision are risk factors for postoperative desaturation.

Purpose: This study was designed to determine the incidence of oxygen desaturation after upper abdominal surgery during the first 48 hr on general surgical wards and also to identify risk factors for oxygen desaturation.

Methods: This descriptive study was conducted in 206 patients not expected to receive supplemental oxygen postoperatively who were undergoing upper abdominal surgery in a tertiary care university hospital. Desaturation was classified either as constant, i.

Comparison of effectiveness between gas flow 1 and 2 l.min(-1) for general anesthesia in infants and children.

Objectives: To determine 1) Success rate of using fresh gas flow (FGF) 1 l.min(-1) compared to 2 l.min(-1) in pediatric patients 2) Necessity of using anesthetic agent analyzer 3) predicting volatile anesthetic concentration 4) cost difference.
