ASSESSMENT OF HEMATOLOGICAL PARAMETERS,  ACID-BASE STATUS AND ARTERIAL BLOOD GAS TEST BEFORE AND AFTER TREATMENT OF ACUTE BRONCHIOLITIS IN CHILDREN

Arterial blood gas (ABG) sampling is an essential investigation for assessment of acid-base status, oxygenation and ventilation in critical care practice. Arterial puncture to obtain arterial blood is more invasive procedure than venous and has more potential complications. To find out the correlation between arterial and peripheral venous blood gas values for pH, PCO2 and bicarbonate. Patients admitted in ICU requiring arterial blood gas analysis to determine their acid-base status or ventilatory status was included in the study. One milliliter of venous blood was obtained in a heparin flushed syringe within 5 minutes of getting arterial blood sample. Both labeled samples were processed immediately. Data were analyzed by student’s t-test. A total of 50 paired samples from 36 patients were evaluated. The mean differences between arterial and venous blood gas values for pH, PCO2 and bicarbonate were 0.02 units, -2.37 mmHg and -0.45 mEq/L respectively. Similarly, the correlation coefficients between arterial and venous parameters were 0.964, 0.881 and 0.906 for pH, PCO2 and bicarbonate respectively, which were statistically significant (p<0.001). Venous pH, PCO2 and bicarbonate showed a very high level of correlation with the respective arterial values.

White rhinoceros anaesthetised with etorphine and azaperone combination develop adverse physiological changes including hypoxia, hypercapnia, acidosis, tachycardia and hypertension. These changes are more marked in field-anaesthetised rhinoceros. This study was designed to develop a technique to improve safety for field-anaesthetised white rhinoceros by tracheal intubation and oxygen insufflation. Twenty-five free-ranging white rhinoceros were anaesthetised with an etorphine and azaperone combination for translocation or placing microchips in their horns. Once anaesthetised the rhinoceros were monitored prior to crating for transportation or during microchip placement. Physiological measurements included heart and respiratory rate, blood pressure and arterial blood gas samples. Eighteen rhinoceros were intubated using an equine nasogastric tube passed nasally into the trachea and monitored before and after tracheal insufflation with oxygen. Seven rhinoceros were not intubated or insufflated with oxygen and served as controls. All anaesthetised rhinoceros were initially hypoxaemic (percentage arterial haemoglobin oxygen saturation (% O2Sa) = 49 % + 16 (mean + SD) and PaO2 = 4.666 + 1.200 kPa (35 + 9 mm Hg)), hypercapnic (PaCO2 = 8.265 + 1.600 kPa (62 + 12 mm Hg)) and acidaemic (pHa = 7.171 + 0.073 ). Base excess was -6.7 + 3.9 mmol/ℓ, indicating a mild to moderate metabolic acidosis. The rhinoceros were also hypertensive (systolic blood pressure = 21.861 + 5.465 kPa (164 + 41 mm Hg)) and tachycardic (HR = 107 + 31/min). Following nasal tracheal intubation and insufflation, the % O2Sa and PaO2 increased while blood pHa and PaCO2 remained unchanged.Tracheal intubation via the nose is not difficult, and when oxygen is insufflated, the PaO2 and the % O2Sa increases, markedly improving the safety of anaesthesia, but this technique does not correct the hypercapnoea or acidosis. After regaining their feet following reversal of the anaesthesia, the animals' blood gas values return towards normality.
