Abstract

Background: Intra-abdominal hypertension (IAH) is defined as the presence of either an intra-abdominal pressure (IAP) ${\geq}12mmHg$ or an abdominal perfusion pressure (APP = mean arterial pressure - IAP) ${\leq}60mmHg$. Abdominal compartment syndrome (ACS) is defined as the presence of an IAP ${\geq}20mmHg$ together with organ failure. The purpose of this study was to investigate the prevalence of IAH and ACS on the day of admission and the effects of these maladies on the prognosis of critically ill patients in the ICU. Methods: At the day of admission to the ICU, the IAP was recorded by measuring the intravesicular pressure via a Foley catheter. The APACHE II and III scores were checked and SAPS II was also scored during the days the patients were in the ICU. The primary end point was the prevalence of IAH and ACS at the day of admission and the correlation between them with the 28-days mortality rate. The measurement of IAP continued until the 7th day or the day when the patient was transferred to the general ward before 7th day, unless the patient died or a Foley catheter was removed before 7th day. Patients were observed until death or the 28th day. Results: A total of 111 patients were enrolled. At the day of admission, the prevalence of IAH and ACS were 47.7% and 15.3%, respectively and the mean IAP was $15.1{\pm}8.5mmHg$. The rates of IAH for the survivor and the non-survivor groups were 56.5% and 71.4%, respectively, and these were not significantly different (p=0.593). Yet the rates of ACS between these two groups were significantly different (4/62, 6.5% vs. 13/49, 26.5%; Odds Ratio = 5.24, 95% CI = 1.58-17.30, p=0.004). Conclusion: In the present study, the prevalence of IAH was 47.7% and the prevalence of ACS was 15.3% on the day of admission. ACS was associated with a poor outcome for the critically ill patients in the ICU.

연구배경: IAP의 증가는 혈류량을 감소시켜 여러 장기에 영향을 준다. IAH는 IAP가 12 mmHg 이상 또는 APP가 60 mmHg 이하로, ACS는 IAP가 20 mmHg 이상이면서 동시에 하나 이상의 장기 손상이 있는 경우로 각각 정의한다. 저자들은 중환자에서 IAH 및 ACS의 유병률과 이들이 환자의 예후에 미치는 영향을 고찰하고자 하였다. 방 법: 고려대학교 의료원 중환자실에 입원하는 내과계 환자를 대상으로 하여, APACHE II 및 III 점수, SAPS II 점수를 기록하였다. IAP는 삼중관 요도관을 통하여, 입원 7일째까지 매일 3회 측정하였고, 환자가 사망하거나 일반 병실로 전실 또는 요도관을 제거할 때까지 계속하였다. 환자의 예후는 28일을 기준으로 판단하였다. 결 과: 총 111명 대상 환자들의 입원 1일 IAH 및 ACS의 유병률은 각각 47.7%, 15.3%였다. 사망군과 생존군 사이에 IAH의 유병률은 유의한 차이가 없었으나, ACS는 사망군에서 더 높았다 (p=0.004). 사망군에서 IAP는 더 높았고 (p=0.012), APP는 유의하게 낮았다 (p<0.001). 결 론: 중환자에서 입원 1일에 측정한 IAP의 증가, APP의 감소 및 ACS 발생은 환자의 사망과 연관이 있을 것으로 판단된다.
