BACKGROUND AND AIMS: Thoracotomy incision following patent ductus arteriosus (PDA) ligation surgery is often associated with severe post-operative pain that has deleterious effects on respiratory function. We aimed to assess pain relief with thoracic paravertebral block using either bupivacaine or ropivacaine in these surgeries. METHODS: One hundred paediatric patients of age group between 2 and 10 years undergoing PDA ligation surgery were randomised either to bupivacaine or ropivacaine group in this prospective double-blinded study...

BACKGROUND: Clonidine has been advocated as a valid alternative for premedication in children but one of the few limitations is its association with reduced heart rate (HR), which thus raises the question of the safety of clonidine as premedication in children. The aim of this study was to investigate the incidence of bradycardia in children premedicated with oral or intravenous clonidine as compared to children not receiving pharmacologic premedication. METHODS: An open, nonrandomized, observational study design was used...

About 40% of adults are habitual snorers. 2% of women and 4% of men between 30 and 60 years of age present additional sleep disordered breathing. There is a continuous spectrum from simple to disease-causing snoring ranging from merely disturbing noises to pharyngeal obstructions and breathing pauses. Repetitive episodes of upper airway obstructions lead to frequent arousals from sleep. Sleep fragmentation is responsible for non-refreshing sleep and subsequent excessive daytime sleepiness resulting in reduced performance at work, social problems and a higher risk for accidents...

Neonatal anoxia is a worldwide clinical problem that has serious and lasting consequences. The diversity of models does not allow complete reproducibility, so a standardized model is needed. In this study, we developed a rat model of neonatal anoxia that utilizes a semi-hermetic system suitable for oxygen deprivation. The validity of this model was confirmed using pulse oximetry, arterial gasometry, observation of skin color and behavior and analysis of Fos immunoreactivity in brain regions that function in respiratory control...

BACKGROUND: Oxygen masks with reservoir bags (OMR) are widely used for oxygen therapy in patients with severe respiratory failure. The purpose of the present study was to determine whether OMRs are effectively used in clinical practice. METHODS AND RESULTS: In the first phase of the study on the patients with severe respiratory failure, no apparent respiratory motions of the reservoir bag were noted, and the oxygen saturation level as determined by pulseoximetry (SpO2) did not decrease even after shrinkage of the reservoir bag...

Pulmonary alveolar proteinosis (PAP) is a rare disorder characterized by accumulation of amorphous acellular phospholipid material in the lungs. Whole lung lavage is the standard therapy which gives dramatic clinical improvement and offers a long term survival to these patients. A 43-year-old man suffering from PAP presented to casualty with NYHA grade IV dyspnoea with oxygen saturation (SaO(2)) on pulseoximetry 67% on room air and 78% with O(2) 6 L/min. He underwent whole lung lavage under general anaesthesia using one lung ventilation with 37 F left end bronchial double lumen tube...

PURPOSE: To estimate the importance of respiratory and cardiac effects on signal variability found in functional magnetic resonance imaging data recorded from the brainstem. MATERIALS AND METHODS: A modified version of the retrospective image correction (RETROICOR) method (Glover et al, [2000] Magn Reson Med 44:162-167) was implemented on resting brainstem echo-planar imaging (EPI) data in 12 subjects. Fourier series were fitted to image data based on cardiac and respiratory recordings (pulseoximetry and respiratory turbine), including multiplicative terms that accounted for interactions between cardiac and respiratory signals...

INTRODUCTION: Beta-blockers have, for 25 years, been a commonly used agent in the treatment of raised intraocular pressure (IOP). Beta-blockers can also reduce the pulse rate. With no available literature examining a cohort of patients, this study aims to investigate the resting pulse rates in patients attending a specialist glaucoma clinic in order to identify if routine review of ophthalmic medication use is indicated. METHOD: The resting pulse rates of patients attending a glaucoma clinic were measured using pulseoximetry, with a medical and drug history established for each patient...

OBJECTIVE: To assess the clinical utility of the frequencies of transient increases of pulse rate, non-invasively measured with a pulseoximeter, as an indirect indication of the degree of cortical arousal, measured conventionally on an electroencephalogram (EEG), in obstructive sleep apnea-hypopnea syndrome (OSAHS) patients. PATIENTS AND METHODS: Thirty-three consecutive patients referred with suspected OSAHS were studied. Polysomnography (PSG) with determination of esophageal pressure (Pes) and pulseoximetry was monitored to identify breathing-related EEG arousal (B-Ar) associated with apnea, hypopnea or respiratory effort and the frequencies of pulse rate increases...

To maintain mobility in patients with chronic hypoxemia who are under long-term oxygen therapy, portable oxygen systems are available. They have the disadvantage of a short range. To prolong the range and to reduce the cost of oxygen treatment, demand oxygen delivery systems (DODS) are used. Aim of the study was to compare three DODS (DOC-2000 [D], TransTracheal Inc.; Oxytron [O], Weinmann; Pulsair [P], DeVilbiss, Sunrise Medical) with continuous oxygen delivery. 17 patients (age 67.82 +/- 9.46 years; FEV1 1...

Evidence of pre-emptive analgetic effect of opioid would offer great potential benefit to patients with postoperative pain, a better pain relief with less opioid. The aim of this double blind randomised trial was to study the effect of intramuscular morphine premedication on postoperative pain. Forty-one patients undergoing total knee arthroplasty were randomly allocated to four groups. Two groups received epidural morphine, 4 mg immediately after operation and 3 mg ten hours later, and two groups the same volume of saline...

This study primarily examined the effect of three endtidal isoflurane concentrations (0.2, 1.0 and 1.4%) on the isocapnic hypoxic ventilatory response (HVR), as well as the hypercapnic ventilatory response (HCVR), in 18 women (ASA I) who were all in the follicular phase of their menstrual cycle. Capnography was used, together with pulseoximetry to indicate desired levels of hypoxia (SpO2 75-80%). This hypoxic challenge resulted, after 3-4 min, in a stable ventilation, and ventilation measurements were then taken during a 90 s period...
