Enteral feeding patients with gastric outlet obstruction.

Patients with upper gastrointestinal obstructions were previously managed with gastric decompression and parenteral feeding. The authors present their experience in 50 patients with obstructions chiefly due to complicated severe acute (n = 31) or chronic cystic pancreatitis (n = 11) using a double-lumen nasogastric decompression and jejunal feeding tube system (NGJ) held in place with a nasal bridle that passes through the obstructed gastroduodenal segments, allowing distal jejunal feeding, and at the same time decompresses the stomach to prevent vomiting and aspiration. The tip of the jejunal tube was placed approximately 40 cm down the jejunum to maintain pancreatic rest. Duration of feeding ranged from 1-145 days (median 25 days); 19 patients were discharged home with tube feeds. Only 1 patient could not tolerate feeding and needed to be converted to parenteral feeding. Average tube life was 14 days, with replacement being needed most commonly for kinking or clogging of the jejunal tube (56%) or accidental dislodgement (24%). The obstruction resolved spontaneously in 60%, allowing resumption of normal eating. Of the patients with severe acute pancreatitis or pancreatic pseudocysts, pancreatic rest resulted in resolution of the disease without surgery in 87%, and need for surgery in the remainder was put off for 31-76 days. Seven patients died predominantly of complications of acute pancreatitis between 1 and 31 days. In conclusion, NGJ feeding provides a relatively safe conservative management for critically ill patients with upper gastrointestinal obstructions, reducing the need for surgery and parenteral feeding.

Early jejunal feeding initiation and clinical outcomes in patients with severe acute pancreatitis.

BACKGROUND: Compared with parenteral nutrition, enteral nutrition reduces infectious complications and mortality in patients with severe acute pancreatitis (SAP). This study used clinical outcomes to investigate the association between time to initiation of distal jejunal feeding (DJF) and time to achievement of goal enteral feeding with clinical outcomes. METHODS: A retrospective chart review was performed on all patients with SAP admitted to the medical intensive care unit (ICU) during a 1-year period. Collected data included demographic information, body mass index (BMI; kg/m(2)), Acute Physiology and Chronic Health Evaluation (APACHE) II scores at admission, time of onset of DJF, time to goal feeding, ICU length of stay, and mortality. RESULTS: Time to starting DJF was longer in nonsurvivors (n = 4) than in survivors (n = 12) (17 vs 7 days, P < .05). All nonsurvivors had BMI >30 kg/m(2) (50% had BMI > 50 kg/m(2)). ICU length of stay was significantly associated with achievement of goal feeding. Three patients never reached goal feeding and spent 45.3 ± 19.6 days in the ICU; 7 patients reached goal feeding within 3 days of initiating DJF and spent 18 ± 1.7 days in the ICU; and 4 patients reached goal feeding within 3 days and spent 10.5 ± 3.5 days in the ICU. APACHE II scores were not significantly different among the 3 groups (16.7 ± 1.5, 12 ± 0.7, and 16.2 ± 1.2, respectively, P > .05). CONCLUSIONS: Early initiation of DJF in the ICU was associated with reduced mortality in this cohort of patients with SAP. Early achievement of jejunal feeding goal early was associated with a shorter ICU length of stay, irrespective of the severity of SAP.

Nursing specialty and burnout.

We examined the relationship between perceived control and burnout among three nursing specialties: nurse practitioners, nurse managers, and emergency nurses. Survey data were collected from 228 nurses from 30 states. Findings indicated that emergency nurses had the least control and the highest burnout, whereas nurse practitioners had the most control and the least burnout. Mediational analyses showed that expected control, hostility, and stressor frequency explained differences between specialties in burnout. The implications of these findings for interventions that reduce burnout and promote nursing retention are discussed.

Effects of cognitive adaptation on the expectation-burnout relationship among nurses.

Burnout has traditionally been thought to result from unrealistically high expectations although research has provided only equivocal support. We explored the impact of cognitive adaptation disposition, including mastery, optimism, and self-esteem, on the expectations-burnout relationship. Nurses (N = 341) who were recruited at professional conferences completed questionnaires that assessed cognitive adaptation, burnout, and initial and current expectations of control. As expected, cognitive adaptation predicted fewer unmet expectations of control, which in turn predicted lower burnout. In addition, optimism and self-esteem predicted lower burnout regardless of perceived initial expectations, whereas mastery lessened the negative consequences of initially high expectations on burnout.

Combining clinical risk with D-dimer testing to rule out deep vein thrombosis.

We sought to determine whether the combination of low-intermediate clinical risk of acute lower extremity deep vein thrombosis (DVT) and negative ELISA D-dimer assay can eliminate the need for duplex ultrasonography. Three hundred thirty-six patients prospectively underwent clinical risk stratification (low, intermediate, and high), D-dimer testing, and duplex ultrasonography. Thirteen of 145 intermediate-risk patients had acute DVT; 11 (85%) had a positive D-dimer. Two of 118 low-risk patients had acute DVT; both had a positive D-dimer. Intermediate-high risk stratification alone had sensitivity of 93.9% (95% CI: 80.3-98.3%) and a NPV of 98.3% (95% CI: 94.0-99.5%) for acute DVT. For all patients, a positive D-dimer alone had a sensitivity of 93.9% (95% CI: 80.3-98.3%) and a NPV of 98.6% (95% CI: 95.1-99.6%). The combination of D-dimer and intermediate-high risk classification had a sensitivity of 100% (95% CI: 89.4-100%) and a NPV of 100% (95% CI: 98.9-100%). In suspected acute lower extremity DVT, the combination of intermediate-high clinical risk and positive D-dimer has a high sensitivity and NPV, possibly eliminating the need for duplex ultrasound in this group of patients.

Complementary and alternative medicine use among urban ED patients: prevalence and patterns.

INTRODUCTION: High rates of complementary and alternative medicine (CAM) use are well documented in the general population without clear clinical benefits. Published studies examining prevalence and patterns of CAM use in emergency patients, however, are limited. The objectives of this study were to describe the prevalence and patterns of CAM use in urban ED patients. METHODS: This was a descriptive study of a convenience sample of 174 patients presenting to the emergency department of a level I, urban, Catholic, tertiary teaching center, with an annual ED census of 43,000. RESULTS: CAM use in our study group was high (47%). Although no sociodemographic predictors of CAM users were found, CAM users were more likely to have chronic conditions (P =.044). One third did not disclose CAM use. Prayer (28%), music therapy (11%), and meditation (10%) were the most frequently used types of CAM reported. DISCUSSION: Patients should be questioned routinely about CAM use, given the high rates of use and low disclosure rates. Knowledge of potential positive and negative effects of CAM, interactions with conventional treatments, and sensitivity toward patients' decisions to opt for CAM are imperative. Spiritual support, where available, should be considered for at least some ED patients. The 3 most common types of CAM reported by ED patients at our level I trauma center were prayer/spirituality, music therapy, and meditation.
