AI Article Synopsis
- The study aimed to assess how the duration of entrapment under rubble affected the health outcomes of crush-syndrome patients after the 1999 Marmara earthquake.
- The observational analysis included 539 patients from 35 hospitals, revealing an average entrapment time of 11.7 hours, with the majority rescued within 48 hours.
- Results indicated that longer time under the rubble was associated with more amputations and specific lab results but unexpectedly did not adversely impact survival or kidney function in patients.
Article Abstract
Objective: To investigate the effect of the time period under the rubble on morbidity and mortality of the crush-syndrome patients after the catastrophic Marmara earthquake that struck northwestern Turkey in August 1999.
Design: Observational study.
Setting: Consecutive admissions to emergency and intensive care units of 35 reference hospitals that treated the renal victims.
Methods: Analysis of questionnaires obtained from these hospitals.
Patients: A total of 539 of 639 crush-syndrome patients whose time under the rubble was identified in the questionnaires.
Results: Mean time under the rubble was 11.7 +/- 14.3 hrs (median, 8 hrs; interquartile range, 6 hrs; range, 0.5-135 hrs). The highest number of patients was entrapped within the 5-8 hrs time stratum, and by the end of 48 hrs, 97% of the victims had been rescued. Nondialyzed victims spent a longer duration under the rubble than dialyzed ones (15.9 +/- 23.1 hrs [median, 7 hrs; interquartile range, 8.5 hrs] vs. 10.3 +/- 9.5 hrs [median, 8 hrs; interquartile range, 6 hrs), p <.001)]. Likewise, in the strata of longer time under the rubble, the percentage of survivors was higher (p =.07). Time under the rubble correlated positively with the number of amputated extremities (p <.001) and admission platelet count (p <.001), and it correlated negatively with admission serum albumin (p <.001). The victims entrapped for >50 hrs (n = 6) were characterized by lower figures of admission blood urea nitrogen (p =.04), serum creatinine (p =.003), hemodialysis sessions, and duration of hemodialysis support (p =.005, for both analyses) compared with victims whose time under the rubble was shorter.
Conclusion: Rescue efforts should continue at least for 5 days after the disaster. Time under the rubble is not an adverse prognostic indicator of survival or renal dysfunction for the patients of crush syndrome, probably because only the victims with mild or moderate injuries can survive under the rubble for longer durations.
