BACKGROUND While the decrease in blood carbon dioxide (CO2 ) secondary to hyperventilation is generally accepted to play a major role in the decrease of cerebral tissue oxygen saturation (SctO2 ), it remains unclear if the associated systemic hemodynamic changes are also accountable. METHODS Twenty-six patients (American Society of Anesthesiologists I-II) undergoing nonneurosurgical procedure...

OBJECTIVE To examine whether use of the active compression-decompression device improves the haemodynamics of cardiopulmonary resuscitation compared with those of conventional cardiopulmonary resuscitation. DESIGN Prospective crossover study. SETTING The accident and emergency department of a university teaching hospital. PATIENTS 36 adult patients with non-traumatic, normothermic, out of...

Bronchiolitis is the most common lower respiratory tract infection among infants and young children [1]. Nowadays oxygenation and clinical assessment are used to decide on hospitalization. Jacob et al. recently explored the role of capnography upon arrival to the Emergency Department and concluded that endtidal carbon dioxide (EtCO2) does not predict neither hospital admission nor discharge eli...

BACKGROUND The aim of our study was to compare classic laryngeal mask airway (LMA-C) with the endotracheal tube (ETT) in pediatric laparoscopic surgery to evaluate the intragastric pressures (IGP) using intragastric pressure monitoring. We also sought to investigate the related influence on respiratory parameters. METHODS The Ethics Committee of the Health Institution approved the study proto...

In 28 healthy adults, we compared the dynamic interaction between respiration and cerebral autoregulation in 2 groups of subjects: those who did and did not develop presyncopal symptoms during 70 degrees passive head-up tilt (HUT), i.e., nonpresyncopal (23 subjects) and presyncopal (5 subjects). Airflow, CO2, cerebral blood flow velocity (CBF), ECG, and blood pressure (BP) were recorded. To det...

BACKGROUND To eliminate the risk of combustion during electrosurgical procedures and to reduce patient discomfort, carbon dioxide (CO2) insufflation has been recommended during colonoscopy. However, air insufflation is still the standard method, perhaps due to the lack of suitable equipment and shortage of randomised studies. AIMS This randomised controlled trial was conducted to assess patie...

Respiratory dysfunction and complications are the most common causes of death in amyotrophic lateral sclerosis. This is a pilot study to observe the changes in respiratory physiology parameters after Sa-am acupuncture treatment. Eighteen ALS patients received Sa-am acupuncture treatment twice a day for 5 days. The EtCO2, SpO2, RR, and pulse rate were measured for 15 min before and during treatm...

STUDY OBJECTIVE to assess the accuracy of nasal capnography for the monitoring of ventilation in extubated morbidly obese patients, following bariatric surgery. DESIGN prospective descriptive study. SETTING Post-anesthesia care unit. PATIENTS 25 consecutive morbidly obese patients admitted to the PACU after open bariatric surgery. INTERVENTION Patients had a nasal cannula designed to ad...

BACKGROUND The aim of the study was to evaluate the comparative effects of propofol infusion versus sevoflurane for maintenance of anesthesia with respect to hemodynamics, recovery characteristics, nausea and vomiting in patients undergoing percutaneous nephrolithotomy. METHODS Forty American Society of Anesthesiologists physical status I-II patients, aged between 22 and 65 years were randoml...

INTRODUCTION Metabolic acidosis confirmed by arterial blood gas (ABG) analysis is one of the diagnostic criteria for diabetic ketoacidosis (DKA). Given the direct relationship between end-tidal carbon dioxide (ETCO2), arterial carbon dioxide (PaCO2), and metabolic acidosis, measuring ETCO2 may serve as a surrogate for ABG in the assessment of possible DKA. The current study focuses on the predi...
