The aim of this study was to measure the sensitivity and specificity of transcutaneous oxygen tension and postocclusive hyperemia testing using laser Doppler flowmetry in patients with primary Raynaud's phenomenon. One hundred patients and one hundred controls were included in the study. Baseline microvascular blood flow and then time to peak flow following occlusion were measured using laser D...

purpose: to compare low volume transconjunctival anterior peribulbar anesthesia with transcutaneous posterior peribulbar anesthesia in phacoemulsification. methods: patients scheduled for phacoemulsification were randomly divided into two groups: in first group 5ml of 2% lidocaine was injected transcutaneously in the posterior orbital space. in the second group, 2ml of 5% lidocaine was injected...

OBJECTIVE To evaluate the use of two phototherapy guidelines for the treatment of hyperbilirubinemia in newborn babies weighing less than 2,000 g. METHODS Eighty-one newborn infants with birth weight less than 2,000 g were studied. They were divided in two groups: the "early" group, which started phototherapy 12 hours after birth, undergoing treatment for at least 96 hours; and the "late" gro...

Transcutaneous immunization refers to the topical application of antigens onto the epidermis. Transcutaneous immunization targeting the Langerhans cells of the skin has received much attention due to its safe, needle-free, and noninvasive antigen delivery. The skin has important immunological functions with unique roles for antigen-presenting cells such as epidermal Langerhans cells and dermal ...

BACKGROUND Accurate and reliable measurement of gas exchange during exercise has traditionally involved arterial cannulation. Non-invasive devices to estimate arterial oxygen (O2) and carbon dioxide (CO2) tensions are now available. A method has been devised and evaluated for measuring gas exchange during exercise with a combined transcutaneous O2 and CO2 electrode. METHODS Symptom limited ex...

background headache is one of the most prevalent investigated complaints in the neurology clinics and is the most common pain-related complaint worldwide. stress is a significant factor that causes and triggers headaches. since healthcare practitioners experience a lot of stress in their careers, they are more prone to headaches. objectives this study was designed to evaluate and compares the e...

We monitored 12 patients undergoing major abdominal surgery using a pulse oximeter (Nellcor N-200) and a transcutaneous oxygen tension monitor (TINA, Radiometer A/S) on the second or third night after operation. Of the shortest hypoxaemic episodes measured with the pulse oximeter (< or = 30 s duration), 78% also occurred in the transcutaneous oxygen tension measurement. Episodes of longer durat...

This document provides guidelines for the terminology, methodology, and for the interpretation of data obtained from the use of skin (transcutaneous) po(2) and pco(2) electrodes. The transcutaneous technique has found special application in newborn infants. The causes of analytical bias with respect to arterial blood gas values, and imprecision obtained with transcutaneous pco(2) electrodes, ar...

Twenty two babies receiving artificial ventilator support were studied on 29 occasions to determine the effects of low levels of positive end expiratory pressure. Mean positive end expiratory pressure during these studies was 2.6 cm H2O. Changes in tidal volume, minute volume, compliance, and transcutaneous gas trends produced by the use of positive end expiratory pressure were investigated. Po...

Close monitoring of the balance between oxygen demand and supply is of great importance during cardiac cardiopulmonary bypass (CPB) surgery. This study was to compare conventional intermittent venous blood gas monitoring with continuous transcutaneous oxygen and carbon dioxide monitoring in infant patients undergoing cardiac surgery with CPB. According to paired data from 29 infant patients und...
