Abstract
Objectives: Evaluation of outcomes of the non-operative management (NOM) of patients who had a blunt splenic injury (BSI) and
the predictors for such outcome.
Patients & Methods: The study included 95, 68, and 61 patients of grades I, II, and III, respectively, according to the AAST grading
of splenic trauma. Patients were evaluated at the intermediate care unit for trauma extent and severity using the New Injury
Severity Scale (NISS), consciousness using Glasgow Coma scale, hemodynamic status, and gave blood samples for estimation of
hemoglobin concentration (Hb. conc.). Patients who showed deterioration were shifted either to urgent splenectomy or admitted
to ICU. The success rate of NOM was defined as control of hemodynamic instability if present, stable splenic injury, the quantity
of hemoperitoneum if present with no need for ICU admission for any indication, and survival rate of patients who had succeeded
or failed NOM.
Results: During NOM, 29 patients were admitted to ICU, 21 patients underwent urgent splenectomy and two patients deceased.
Fifteen of patients admitted to ICU completed their NOM uneventfully and 5 patients underwent elective splenectomy, while 9
patients were deceased. Five of the 26 patients who underwent splenectomy died. The total survival rate was 92.9%; 187 patients
completed NOM (94.4%) and 21 had surgery (80.8%) with a significant difference in favor of NOM. Statistical analyses defined high
at admission Hb. conc., young age, normal SBP, low NISS score, and low AAST grade were the predictors for NOM success with
decreasing order of importance. Kaplan-Meier regression analysis defined SBP at 106 and 104 mmHg as the cutoff points for the
probability of NOM success and survival.
Conclusion: Proper selection of BSI patients allowed a high success rate (83.5%) and survival rate (94.4%) of NOM. Young aged
patients with low NISS scores and high SBP and hemoglobin concentration are the ideal candidate for NOM with suspected high
success and survival rates, irrespective of injury grade. High SBP and low NISS scores are the best predictors with high positive
predictive value and sensitivity for the success of NOM. |
