    Acid-Base disorders as predictors of early outcomes in major Trauma in a resource limited setting: An observational prospective study
    (Pan African Medical Journal, 2014) Asiimwe, Ian S.; Wangoda, Robert; Kwizera, Arthur; Makobore, Patson; Galukande, Moses
    Mortality from trauma remains a major challenge despite recent substantial improvements in acute trauma care. In trauma care patient resuscitation to correct hypotension from volume loss still majorly relies on use of physiological parameters such as blood pressure, pulse rate, respiratory rate, urine output and oxygen saturation. In resource limited settings these methods may not be sufficient to detect occult tissue hypoxia and the accompanying metabolic derangements. Methods: A prospective observational study carried out at a level I urban Trauma centre; Accident and Emergency unit. Major trauma patients were consecutively recruited into the study. Venous blood samples were drawn foranalysis of serum electrolytes, serum PH and anion gap. The venous blood gas findings were correlated with patients' clinical outcome at two weeks. Ethical approval was obtained. Results: Ninety three major trauma patients were recruited, patients' age ranged from 12 months to 50 years. Forty nine patients (53%) were acidotic (PH less than 7.32), 39 patients (42%) had low bicarbonate (bicarbonate level less than 21 mmol), 54 patients (58%) had high corrected anion gap (anion gap corrected of 16 or more). Fourteen patients (15%) developed secondary organ failure and 32 (34%) patients died. Conclusion: Metabolic acidosis is common among major trauma patients, its severity may be related to delay in initiating care. Acid base derangements were predictors of mortality among major trauma patients in this resource limited setting

    Deep venous thrombosis after major abdominal surgery in a Ugandan hospital: a prospective study
    (International journal of emergency medicine, 2013) Muleledhu, Andrew L.; Galukande, Moses; Makobore, Patson; Mwambu, Tom
    Deep venous thrombosis (DVT) is a major cause of morbidity and mortality among postoperative patients. Its incidence has been reported to range between 16% and 38% among general surgery patients and may be as high as 60% among orthopaedic patients. The most important clinical outcome of DVT is pulmonary embolism, which causes about 10% of hospital deaths. In over 90% of patients, occurrence of DVT is silent and presents no symptoms until onset of pulmonary embolism and/or sudden death. The only effective way of guarding against this fatal condition is therefore prevention/prophylaxis. However, prophylaxis programs are usually based on the estimated prevalence of DVT in that particular community. There is currently no data concerning rates of postoperative DVT in Uganda. The purpose of the study was therefore to determine the prevalence of DVT among postoperative patients at Mulago Uganda’s National Referral Hospital. Methods: A cross sectional descriptive study was conducted between March and June 2011. Eligible patients were identified and screened and patient details were collected. Clinical examinations were done on postoperative days (PODs) 1, 2, and 4 and Doppler ultrasounds were done on POD 7 and POD 21 to assess for DVT. Patients found with DVT were treated appropriately according to local treatment guidelines. Results: A total of 82 patients were recruited, 4/82 (5%) had DVT. The most common risk factor was cancer. The overall mean age was 45 years (range 20–83 years). The male to female ratio was 1.6:1. Participants with more than one risk factor for DVT were 16/82 (20%). Conclusions: Prevalence of DVT among major post-abdominal surgery patients was low (5%). Cancer was the most common associated factor apart from surgery.

    Serum lactate as a predictor of early outcomes among trauma patients in Uganda
    (International journal of emergency medicine, 2014) Okello, Michael; Makobore, Patson; Wangoda, Robert; Upoki, Alex; Galukande, Moses
    Trauma is the leading cause of death in the developed world. Accurate assessment of severity of injuries is critical in informing treatment choices. Current models of assessing severity of injury are not without limitations. The objective of this study therefore was to determine the diagnostic accuracy of serum lactate assays in assessing injury severity and prediction of early outcomes among trauma patients. Methods: This was a cross-sectional analytical study. Consecutive series of all eligible patients had a single venous blood sample drawn for lactate assay analysis (index test) and a concurrent Kampala Trauma Score (KTS) II value determination (reference test). Admitted patients were followed up to assess early outcomes (length of hospital stay and mortality). Results: Out of the 502 trauma patients recruited, 108 (22%) were severely injured, 394 (78%) had non-severe injuries, and 183 were admitted. There was a significant difference between median (interquartile range (IQR)) lactate levels among the severely injured (4.3 (2.6, 6.6)) and the non-severely injured (2.4 (1.6, 3.5), p < 0.001). After a 72-h follow-up of the admitted patients, 102 (56%) were discharged, 61 (33%) remained in the hospital, 3 (2%) remained in the ICU, and 17 (3%) had died. The area under the receiver operator characteristic (ROC) curve was 0.75 for injury severity. Serum lactate ≥2.0 mmol/l had a hazard ratio of 1.10 (p < 0.001) for emergency department disposition, 4.33 (p = 0.06) for the 72-h non-discharge disposition, and 1.19 (p < 0.001) for 72-h mortality. Serum lactate ≥2.0 mmol/l at admission was useful in discriminating severe from non-severe injuries with a sensitivity of 88%, specificity of 38%, PPV of 30%, and NPV of 92%.
