A retrospective study of 23 patients with spinal tuberculosis (TB) was conducted, with special attention to the diagnosis and method of treatment. Computerised tomography (CT) was found to be the diagnostic radiological modality of choice. Triple therapy with the new anti-tuberculous drugs and posterior or posteriolateral decompression succeeded in decompressing the cord and eliminating the tuberculous lesion in all cases. The outcome was comparable to series where anterior decompression was adopted. None of the patients required spinal fusion. Erythrocyte sedimentation rate was the most consistent blood test in suggesting the diagnosis and was the best tool for evaluating a patient's response to treatment. The average hospital stay was only 17 days, which speaks favourably for the surgical management of tuberculous spondylitis.
Background: Electrolyte administration during massive transfusion without readily available calcium laboratory values is likely ubiquitous but not well standardized. We aimed to quantify the incidence, degree, and timing of hypocalcemia during the first 24 hours after initiation of a massive transfusion with the institutional massive transfusion protocol (MTP). We hypothesized that hypocalcemia is prevalent during acute resuscitation (first six hours) despite efforts of the treatment team to replete calcium during active resuscitation.Methods: A retrospective chart review of all patients who underwent MTP at our institution between January 1, 2017, and December 31, 2017, was performed. The primary outcome was hypocalcemia from a massive transfusion during the first six hours after the initiation of the MTP. Secondary outcomes of interest included hypercalcemia, hypomagnesemia, hospital mortality, peak and nadir timing of hypocalcemia and hypercalcemia, calcium supplementation, and calcium supplementation timing. Calcium administration and blood product transfusion is reported relative to the start of the MTP. The association between the total amount of calcium administered and the total number of blood products transfused was assessed.Results: Data from 52 massive transfusions were analyzed. Ninety-seven percent of patients were hypocalcemic during the first six hours of resuscitation. The nadir occurred after median of eight units of blood product were given, (interquartile range {IQR}: 4-16). Calcium supplementation correlated with the total number of blood products transfused (ρ = 0.47, p < 0.01). Patients in whom calcium was supplemented received more blood products when compared to patients in whom calcium was not supplemented (median: 16, IQR: 12-26 vs. median: 9, IQR: 7-12, p < 0.01).Conclusions: Hypocalcemia from massive transfusion is common. The incidence of hypocalcemia in MTP has been reported to be 85-97%. Calcium supplementation that is not standardized in MTP may lead to underutilization during massive transfusion and to hypocalcemia in these patients.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
