ABSTRACT

BACKGROUND

It is well known that various ABD are very common in critical illness. Prompt correction of ABD and treating the underlying cause as soon as possible is the key to reduce morbidity and mortality. Although ABDs are quite common in the respiratory ICU and are generally associated with significant morbidity and mortality, the precise incidence and prevalence of ABDs have not been fully determined in patients presenting at the respiratory ICU. Many of the studies that have been conducted on this topic have included critical patients in multidisciplinary intensive care units and emergency departments but there are no studies particularly in Respiratory ICU. The current study was planned with an objective of assessing the pattern of ABG with severity and prognosis of disease in RICU.

METHODS

In this prospective observational study, all patients admitted in RICU of the Maharajah’s Institute of Medical Sciences between January 2016 and August 2017 for a period of 18 months were included and subjected to ABG sampling.

RESULTS

All ABD types were most commonly observed in patients over 60 years of age. In cases of ABD, COPD, Pneumonia was the most common diagnosis (26%). The most common ABD seen in COPD is RAC + MAL (86.9%) and the most common ABD seen in pneumonia is MAC + RAL (52.1%). Of the 100 cases with an ABD, 27 patients (27%) had simple ABD and 73 patients (73%) had mixed ABD. The most common ABD was a mixed respiratory acidosis and metabolic alkalosis (RACMAL) (n=37, 37%).

CONCLUSIONS

Acid-base disorders are common in patients presenting at the ED, especially among very sick patients. Thus, ABGs should definitely be evaluated in the management of such patients. Of the ABDs RAC + MAL and MAC + RAL is the most common. Respiratory acidosis was more common among SABD cases. All types of acid-base disorders are observed primarily in patients over 65 years of age.

KEY WORDS

ABD, SABD, MABD, RAC, RAL, MAC, MAL
