RESUMO
BACKGROUND: Vaso-occlusive crisis (VOC) is one of the acute complications of sickle-cell disease (SCD). Treatment mainly relies on hydration and pain control by analgesics. The specific aim of this study was to assess potential health outcomes within the first 72 h of admission between intermittent and patient-controlled analgesia (PCA) by opioids among VOC patients. METHODS: A retrospective chart review study was conducted to determine SCD patients with VOC. Using the hospital electronic system, the following data were collected: patient's age, gender, blood pressure, heart rate, respiratory rate, oxygen saturation, and pain score on admission and daily for 3 days as well as the cumulative opioid analgesic dose for 72 h which is reported as morphine equivalent. RESULTS: One hundred and seventeen patients were screened over a period of 5 years. Of those, 99 (84.6%) met the study inclusion criteria, and 18 patients (15.4%) were excluded from the study. During the first 72 h of admission, a significant reduction in pain score was observed in patients on intermittent intravenous (IV) administration compared to those in the PCA group (P < 0.0004) where the mean pain scores were 3 and 5, respectively. The total amount of morphine administered over 72 h of admission was significantly higher in PCA group (777 ± 175 mg) as compared to the intermittent IV administration group (149 ± 74 mg) (P < 0.000003). Clinically significant hypotension or respiratory depression was not observed in both groups over the 72 h of admission. CONCLUSION: During the first 72 h of admission, intermittent IV administration of morphine was more effective than PCA infusion in pain control.
RESUMO
BACKGROUND/AIMS: In Saudi Arabia, colorectal cancers (CRCs) are registered as the second most common cancers. However, no data has been reported about correlation of the severity of the anemia and pretreatment platelets level with clinicopathological features of CRCs. We aimed to evaluate the association between pretreatment hemoglobin and platelets level and the clinicopathological features of CRC patients in Saudi Arabia. MATERIALS AND METHODS: Between September 2005 and November 2011, One hundred and fifty-four confirmed CRC patients underwent thorough physical examination, blood investigations, endoscopic ultrasonography (EUS), and computed tomography (CT) for staging before surgery. Findings of physical assessment, EUS, CT, and pathological specimens were correlated with pretreatment hemoglobin and platelets levels the Pearson-Kendall tau correlative coefficients. RESULTS: The mean age of cohort was 56.6 years (range: 26-89). Left-sided CRC were predominant (97 patients; 63%). Mean size of primary tumor was 6 cms (1-18) SD ± 3.55. Mean values of hemoglobin, red blood cells, hematocrit, white blood cells, and platelets were 11.9 SD ± 2.3, 35.5 SD ± 5.7, 4.43 × 10 6 /mL SD ± 0.6, 7.67 10 6 /mL SD ± 2.44, and 343 × 10 3 /mL SD ± 164.4, respectively. Pretreatment hemoglobin was inversely correlated with primary tumor size (R: 0.71, R2: 1.55, P = 0.0001) and nodal status (R: 0.02, R2: 0.05, P = 0.01). Right-sided CRC had significantly low pretreatment hemoglobin levels ( P = 0.001). Interestingly, pretreatment thrombocytosis was seen only in right-sided CRC (P = 0.0001). CONCLUSION: Pretreatment anemia and thrombocytosis were found mainly in right-sided CRCs and advanced primary and nodal stages. Pretreatment hemoglobin and thrombocytosis can be considered as useful prognostic markers in CRC patients.
