ABSTRACT
BACKGROUND: Sepsis-induced multiple-organ failure (MOF) has plagued surgical intensive care units (ICUs) for decades. Early nutrition (principally enteral) improves hospital outcomes of high-risk ICU patients. The purpose of this study is to document how the growing epidemic of chronic critical illness (CCI) patients responds to adequate evidence-based ICU nutrition. METHODS: This retrospective post hoc subgroup analysis of an ongoing sepsis database identified 56 CCI patients who received early, adequate nutrition per an established surgical ICU protocol compared with 112 matched rapid-recovery (RAP) patients. RESULTS: The matched CCI and RAP groups had similar baseline characteristics. Serial biomarkers showed that CCI patients remained persistently inflamed with ongoing stress metabolism and that despite receiving evidence-based protocol nutrition, they had persistent catabolism and immunosuppression with more secondary infections. More CCI patients were discharged to poor nonhome destinations (ie, skilled nursing facilities, long-term acute care, hospice) (81% vs 29%, P < 0.05). At 12-month follow-up, CCI patients had worse functional status by Zubrod score (3.17 vs 1.62, P < 0.001) and Short Physical Battery Testing (4.78 vs 8.59, P < 0.02), worse health-related quality of life by EQ-5D-3L descriptive measures (9.07 vs 7.45, P < 0.003), and lower survival (67% vs 92%, P < 0.05). CONCLUSIONS: Despite early, adequate, evidence-based ICU nutrition, septic surgical ICU patients who develop CCI exhibit persistent inflammation, immunosuppression, and catabolism with unacceptable long-term morbidity and mortality. Although current evidence-based ICU nutrition may improve short-term ICU outcomes, novel adjuncts are needed to improve long-term outcomes for CCI patients.

BACKGROUND: To standardize care and promote early fascial closure among patients undergoing emergent laparotomy and temporary abdominal closure (TAC), we developed a protocol addressing patient selection, operative technique, resuscitation strategies, and critical care provisions. We hypothesized that primary fascial closure rates would increase following protocol implementation with no difference in complication rates. STUDY DESIGN: We performed a retrospective cohort analysis of 138 adult trauma and emergency general surgery patients who underwent emergent laparotomy and TAC, comparing protocol patients (n = 60) to recent historic controls (n = 78) who would have met protocol inclusion criteria. The protocol includes low-volume 3% hypertonic saline resuscitation, judicious wound vacuum fluid replacement, and early relaparotomy with sequential fascial closure. Demographics, baseline characteristics, illness severity, resuscitation course, operative management, and outcomes were compared. The primary outcome was fascial closure. RESULTS: Baseline characteristics, including age, American Society of Anesthesiologists class, and postoperative lactate levels, were similar between groups. Within 48 hours of initial laparotomy and TAC, protocol patients received significantly lower total intravenous fluid resuscitation volumes (9.7 vs. 11.4 L, p = 0.044) and exhibited higher serum osmolarity (303 vs. 293 mOsm/kg, p = 0.001). The interval between abdominal operations was significantly shorter following protocol implementation (28.2 vs. 32.2 hours, p = 0.027). The incidence of primary fascial closure was significantly higher in the protocol group (93% vs. 81%, p = 0.045, number needed to treat = 8.3). Complication rates were similar between groups. CONCLUSIONS: Protocol implementation was associated with lower crystalloid resuscitation volumes, a transient hyperosmolar state, shorter intervals between operations, and higher fascial closure rates with no difference in complications. LEVEL OF EVIDENCE: Therapeutic study, level IV.

BACKGROUND: Our objective was to establish the safety of 3% hypertonic saline (HTS) resuscitation for trauma and acute care surgery patients undergoing emergent laparotomy and temporary abdominal closure (TAC) with the hypothesis that HTS administration would be associated with hyperosmolar hypercholoremic acidosis, lower resuscitation volumes, and higher fascial closure rates, without adversely affecting renal function. METHODS: We performed a retrospective cohort analysis of 189 trauma and acute care surgery patients who underwent emergent laparotomy and TAC, comparing patients with normal baseline renal function who received 3% HTS at 30 mL/h (n = 36) to patients with standard resuscitation (n = 153) by baseline characteristics, resuscitation parameters, and outcomes including primary fascial closure and Kidney Disease: Improving Global Outcomes stages of acute kidney injury. RESULTS: The HTS and standard resuscitation groups had similar baseline illness severity and organ dysfunction, though HTS patients had lower serum creatinine at initial laparotomy (1.2 mg/dL vs. 1.4 mg/dL; p = 0.078). Forty-eight hours after TAC, HTS patients had significantly higher serum sodium (145.8 mEq/L vs. 142.2 mEq/L, p < 0.001), chloride (111.8 mEq/L vs. 106.6 mEq/L, p < 0.001), and osmolarity (305.8 mOsm/kg vs. 299.4 mOsm/kg; p = 0.006), and significantly lower arterial pH (7.34 vs. 7.38; p = 0.011). The HTS patients had lower intravenous fluid (IVF) volumes within 48 hours of TAC (8.5 L vs. 11.8 L; p = 0.004). Serum creatinine, urine output, and kidney injury were similar between groups. Fascial closure was achieved for 92% of all HTS patients and 77% of all standard resuscitation patients (p = 0.063). Considering all 189 patients, higher IVF resuscitation volumes within 48 hours of TAC were associated with decreased odds of fascial closure (odds ratio, 0.90; 95% confidence interval, 0.83-0.97; p = 0.003). CONCLUSION: Hypertonic saline resuscitation was associated with the development of a hypernatremic, hyperchloremic, hyperosmolar acidosis, and lower total IVF resuscitation volumes, without adversely affecting renal function. These findings may not be generalizable to patients with baseline renal dysfunction and susceptibility to hyperchloremic acidosis-induced kidney injury. LEVEL OF EVIDENCE: Prognostic study, level II.

BACKGROUND: Differentiating between partial adhesive small bowel obstruction (aSBO) likely to resolve with medical management and complete obstruction requiring operative intervention remains elusive. We implemented a standardized protocol for the management of aSBO and reviewed our experience retrospectively. METHODS: Patients with symptoms of aSBO were admitted for intravenous fluid resuscitation, bowel rest, nasogastric tube decompression, and abdominal examinations every 4 hours. Laboratory values and a computed tomography scan of the abdomen and pelvis with intravenous contrast were obtained. Patients with peritonitis or computed tomography scan findings suggesting bowel compromise were taken to the operating room for exploration following resuscitation. All other patients received 80 mL of Gastroview (GV) and 40 mL of sterile water via nasogastric tube. Abdominal plain films were obtained at 4, 8, 12, and 24 hours. If contrast did not reach the colon within 24 hours, then operative intervention was performed. RESULTS: Over 1 year, 91 patients were admitted with aSBO. Sixty-three patients received GV, of whom 51% underwent surgery. Twenty-four patients went directly to the operating room because of clinical or imaging findings suggesting bowel ischemia. Average time to surgery was within 1 day for the no-GV group and 2 days for the GV group. Patients passing GV to the colon within 5 hours of administration had a 90% rate of resolution of obstruction. There was a direct relationship between the duration of time before passing GV to the colon and hospital length of stay (HLOS) (r = 0.459). Patients who received GV and did not require surgery had lower HLOS (3 days vs. 11 days, p < 0.0001). CONCLUSION: The GV protocol facilitated early recognition of complete obstruction. Administration of GV had diagnostic and therapeutic value and did not increase HLOS, morbidity, or mortality. LEVEL OF EVIDENCE: Therapeutic study, level V. Epidemiologic study, level V.
