Objective: This study was aimed to compare between arterial and peripheral venous samples for blood gases and acid base status in critically ill patients and to evaluate if venous sample is a better alternative for initial assessment and resuscitation.Methods: This prospective study was conducted on 50 patients of more than 18 years of age in the department of Critical Care Medicine, BIRDEM General Hospital. Arterial and peripheral venous samples were taken within five minutes of each other and analyzed immediately for blood gases and acid base status. Mean difference and Pearson's product moment correlation coefficient was used to compare the result.Results: Mean difference and correlation coefficient between arterial and peripheral venous sample for pH, bicarbonate, base excess, PaCO2 and TCO2 value showed high correlation (r > 0.9). Comparison of electrolyte and hematocrit between arterial and peripheral venous sample also showed high correlation (r > 0.9).Conclusion: Peripheral venous gas analysis for pH, bicarbonate, base excess, PCO2 and Electrolytes (Na+, K+) show good correlation with the respective arterial values. This result suggests that venous estimations can be an acceptable alternative to arterial measurements for managing critically ill patients.Bangladesh Crit Care J September 2016; 4 (2): 92-95

Metabolic acidosis is prevalent among critically ill patients and the common cause of metabolic acidosis in ICU is lactic acidosis. However, not all ICUs can provide lactate measurement. The traditional method that uses Henderson-Hasselbach equation (completed with BE and AG) and alternative method consisting of Stewart and its modification (BDEgap and SIG), are acid-base balance parameters commonly used by clinicians to determine metabolic acidosis in critically ill patients. The objective of this study was to discover the association between acid-base parameters (BE, AGobserved, AGcalculated, SIG, BDEgap) with lactate level in critically ill patients with metabolic acidosis. This was an analytical study with a cross-sectional design. Eighty-four critically ill patients hospitalized in the ICU department Dr. M. Djamil Padang Hospital were recruited in this study from January to September 2016. Blood gas analysis and lactate measurement were performed by potentiometric and amperometric method while electrolytes and albumin measurement were done by ISE and colorimetric method (BCG). Linear regression analysis was used to evaluate the association between acid-base parameters with lactate level based on p-value less than 0.05. Fourty five (54%) were females and thirty-nine (46%) were males with participant’s ages ranged from 18 to 81 years old. Postoperative was the most reason for ICU admission (88%). Linear regression analysis showed that p-value for BE, AGobserved, AGcalculated, SIG and BDEgap were 119; 0.967; 0.001; 0.001; 0.689, respectively. Acid-base balance parameters which were mostly associated with lactate level in critically ill patients with metabolic acidosis were AGcalculated and SIG.

Context: Central venous access device (CVAD) bundles for insertion and maintenance demonstrate a reduction in the frequency of complications and bloodstream infection when implemented with compliance monitoring, with the reported success of CVAD bundles. Aim: This study aimed to examine the effect of central venous catheter care bundle implementation on outcomes of critically ill patients. Methods: Quasi-experimental research (pre/post-test design) used to achieve the aim of this study. The study conducted at general and surgical intensive care units affiliated to Menoufia University and teaching hospital. Two study samples recruited in this study. All nurses working at the ICUs, as mentioned above, were recruited in this study. They were 6o critical care nurses. A convenient sample of all available critically ill patients at the time of the study was subjected to treatment via a central venous catheter. Four study tools used to collect the data of this study. These are a structured interview questionnaire, CVC nurses’ knowledge assessment questionnaire, nurses’ compliance assessment checklists, and patient complications assessment records. Results: The study result showed a highly statistically significant difference between pre and post-test knowledge scores of studied nurses regarding assisting line insertion, removal, maintenance, care, and infection control practices. Besides, a highly statistically significant difference between pre and post-test scores of nurses’ compliance to central venous catheter care practices of assisting in CVC insertion, blood sample withdrawal, medication and fluid administration, CVP measurements, CVC removal, and the management of central venous line complications. The study also revealed a highly statistically significant difference between the study and control group patients regarding the central venous catheter complications. However, signs of infection were the most frequent complications in both groups. Conclusion. The study concluded that a statistically significant difference between pre and post nurses’ knowledge and compliance with the CVC care bundle. The patients’ outcomes were also improved significantly after the implementation of the CVC care bundle compared to the controls. The study recommended the adoption of the current care bundle that should be disseminated and updated following the international organizations’ recommendation for implementing evidence-based practices for successful central line-associated bloodstream infection (CLABSI) prevention.
