Acute liver failure (ALF) following yellow phosphorous (YP) ingestion is similar to acetaminophen-induced ALF and it has become a public concern in our region. This study assessed low volume therapeutic plasma exchange (LV-TPE) efficacy in improving the transplant free survival in YP poisoning.
Adult patients with toxicology reports of YP and ALF requiring critical care were included in the study. LV-TPE was planned for three consecutive days and three more if required. Performed 1.3 to 1.5 plasma volume replacing with 0.9% normal saline, 5% human albumin solution, and fresh frozen plasma based on ASFA 2019 criteria. MELD score, laboratory parameters, LV-TPE details were captured. The study end point was clinical outcome of the patients.
Among 36 patients, 19 underwent LV-TPE and 17 opted out of LV-TPE and they were included as a control arm. The MELD score was 32.64 ± 8.05 and 37.83 ± 9.37 in both groups. There were 13 survivors in LV-TPE group leading to a 68.42% reduction in mortality. The coagulation and biochemical parameters showed a significant percentage change after LV-TPE. Refractory shock, delay in initiating procedure and acidosis were independent predictors of mortality.
A well-timed LV-TPE improves the survival of patients with ALF due to YP poisoning.
黄磷（YP）摄入后导致的急性肝衰竭（ALF）类似于对乙酰氨基酚引起的 ALF，这在我们地区引起了公众关注。本研究评估了小体积治疗性血浆置换（LV-TPE）在改善YP 中毒所致 ALF 患者无肝移植存活率方面的疗效。
纳入有 YP 中毒和 ALF 需要重症监护的毒理学报告的成年患者。计划连续 3 天进行 LV-TPE，如果需要则再进行 3 天。根据 ASFA 2019 标准，用 0.9%生理盐水、5%人血白蛋白溶液和新鲜冷冻血浆置换 1.3 至 1.5 个血浆容量。记录 MELD 评分、实验室参数和 LV-TPE 细节。研究终点为患者的临床结局。
在 36 名患者中，19 名接受了 LV-TPE，17 名患者选择不接受 LV-TPE，他们被纳入对照组。LV-TPE 组和对照组的 MELD 评分分别为 32.64±8.05 和 37.83±9.37。LV-TPE 组有 13 名幸存者，死亡率降低了 68.42%。凝血和生化参数在 LV-TPE 后显示出显著的百分比变化。难治性休克、延迟开始治疗和酸中毒是死亡率的独立预测因素。
及时进行 LV-TPE 可提高 YP 中毒所致 ALF 患者的生存率。
