On induction of anesthesia (for intubation), the patient hemodynamics became very unstable prompting the initiation of both Epinephrine and Nor-Epinephrine Intra-venous (IV) infusions. Glucose 10% IV infusion and Insulin IV infusion were also started. The pre-transfer management also included Hydrocortisone IV justified by the marked hemodynamic instability and mediocre response to inotropic su...

We report a case in which the use of benzocaine spray to facilitate awake fiber optic intubation (FOI) in a patient with a difficult airway caused methemoglobinemia intraoperatively. Local benzocaine was sprayed to numb the patient's airway for a total time of one second, fifteen minutes later SpO2 decreased to 85% on the pulse oximeter. Arterial blood gas (ABG) showed a MetHb of 24.6% of total...

Case 1 A 55 year-old man with a history of COPD presents to the emergency room with a two day history of worsening shortness of breath which came on following a recent viral infection. In the emergency room, his oxygen saturation is 88% on room air. He is working hard to breathe and is only speaking in short sentences. On exam, he has diffuse wheezes and a prolonged expiratory phase. His chest ...

A thermostable urinary homologue of the plasma aldosterone-binding globulin (ABG), designated ABG-TsU, was isolated and purified by differential ultrafiltration, ion exchange chromatography, and gel filtration to electrophoretic homogeneity. Scatchard plot analysis using highly purified ABG-TsU demonstrated reversible high-affinity low-capacity binding at separate sites for aldosterone and dehy...

OBJECTIVE General anesthesia causes reduction of functional residual capacity. And this decrease can lead to atelectasis and intrapulmonary shunting in the lung. In this study we want to evaluate the effects of 5 and 10cmH2O PEEP levels on gas exchange, hemodynamic, respiratory mechanics and systemic stress response in laparoscopic cholecystectomy. METHODS American Society of Anesthesiologist...

in stable conditions.4 Acute effects of N-CPAP on arterial blood gas (ABG) values in a group of our patients with stable COPD are shown in Table 1. Finally, we agree together with de Lucas et all that the beneficial effect of N-CPAP in COPD is predominantly related to a better ventilation/perfusion relationship. In one 65-year-old patient with COPD, we performed a lung ventilatory scan (Fig 1) ...

OBJECTIVE To investigate whether benchtop auto-analyzers (AAs) and arterial blood gas (ABG) analyzers, for measuring electrolyte levels of patients admitted to intensive care units (ICU), are equal and whether they can be used interchangeably. MATERIALS AND METHOD This study was conducted on 98 patients admitted to the ICU of the Institute of Medicine, Kathmandu, Nepal between 15 October and ...

BACKGROUND Extubation is associated with the risk of complications such as accumulated secretion above the endotracheal tube cuff, eventual atelectasia following a reduction in pulmonary volumes because of a lack of physiological positive end expiratory pressure, and intra-tracheal suction. In order to reduce these complications, and, based on basic physiological principles, a new practical ext...

BACKGROUND High inspiratory oxygen concentrations are frequently administered in ventilated patients in the intensive care unit (ICU) but may induce lung injury and systemic toxicity. We compared beliefs and actual clinical practice regarding oxygen therapy in critically ill patients. METHODS In three large teaching hospitals in the Netherlands, ICU physicians and nurses were invited to compl...

The main determinants of mortality after burn injury that can be measured on admission include age, total burn size (% burn), and inhalation injury (INHAL). Other variables, measured during resuscitation, may provide additional information about injury severity. We assessed the utility of early arterial blood gas (ABG) data in predicting mortality after burn injury. Data were limited to samples...
