Abstract
ABSTRACT Damage-control surgery (DCS) is a strategy adopted to limit initial operative interventions in the unstable surgical patient, delaying definitive repairs and abdominal wall closure until physiologic parameters have improved. Although this concept of "physiology over anatomy" was initially described in the management of severely injured trauma patients, the approaches of DCS have become common in the management of nontraumatic intra-abdominal emergencies.While the utilization of damage-control methods in emergency general surgery (EGS) is controversial, numerous studies have demonstrated improved outcomes, making DCS an essential technique for all acute care surgeons. Following a brief history of DCS and its indications in the EGS patient, the phases of DCS will be discussed including an in-depth review of preoperative resuscitation, techniques for intra-abdominal source control, temporary abdominal closure, intensive care unit (ICU) management of the open abdomen, and strategies to improve abdominal wall closure.

Abstract
PURPOSE OF REVIEW The aim of this study was to outline the management of the patient with the open abdomen. RECENT FINDINGS An open abdomen approach is used after damage control laparotomy, to decrease risk for postsurgery intra-abdominal hypertension, if reoperation is likely and after primary abdominal decompression.Temporary abdominal wall closure without negative pressure is associated with higher rates of intra-abdominal infection and evisceration. Negative pressure systems improve fascial closure rates but increase fistula formation. Definitive abdominal wall closure should be considered once oedema has subsided and the patient has stabilized. Delayed abdominal closure after trauma (>24-48 h) is associated with less achievement of fascial closure and more complications. Protective lung ventilation should be employed early, particularly if respiratory compromise is evident. Conservative fluid management and less sedation may decrease delirium and increase definitive abdominal closure rates. Extubation may be performed before definitive abdominal closure in selected patients. Antibiotic therapy should be brief, targeted and guideline concordant. Survival depends on the underlying disease, the closure method and the course of hospitalization. SUMMARY Changes in the treatment of patients with the open abdomen include negative temporary closure, conservative fluid management, early protective lung ventilation, decreased sedation and extubation before abdominal closure in selected patients.

Abstract
PURPOSE Damage control laparotomy (DCL) is used for both traumatic and non-traumatic indications. Failure to achieve primary fascial closure (PFC) in a timely fashion has been associated with complications including sepsis, fistula, and mortality. We sought to identify factors associated with time to PFC in a multicenter retrospective cohort. METHODS We reviewed retrospective data from 15 centers in the EAST SLEEP-TIME registry, including age, comorbidities (Charlson Comorbidity Index [CCI]), small and large bowel resection, bowel discontinuity, vascular procedures, retained packs, number of re-laparotomies, net fluid balance after 24 h, trauma, and time to first takeback in 12-h increments to identify key factors associated with time to PFC. RESULTS In total, 368 patients (71.2% trauma, of which 50.6% were penetrating, median ISS 25 [16, 34], with median Apache II score 15 [11, 22] in non-trauma) were in the cohort. Of these, 92.9% of patients achieved PFC at 60.8 ± 72.0 h after 1.6 ± 1.2 re-laparotomies. Each additional re-laparotomy reduced the odds of PFC by 91.5% (95%CI 88.2-93.9%, p < 0.001). Time to first re-laparotomy was highly significant (p < 0.001) in terms of odds of achieving PFC, with no difference between 12 and 24 h to first re-laparotomy (ref), and decreases in odds of PFC of 78.4% (65.8-86.4%, p < 0.001) for first re-laparotomy after 24.1-36 h, 90.8% (84.7-94.4%, p < 0.001) for 36.1-48 h, and 98.1% (96.4-99.0%, p < 0.001) for > 48 h. Trauma patients had increased likelihood of PFC in two separate analyses (p = 0.022 and 0.002). CONCLUSION Time to re-laparotomy ≤ 24 h and minimizing number of re-laparotomies are highly predictive of rapid achievement of PFC in patients after trauma- and non-trauma DCL. LEVEL OF EVIDENCE 2B.

Dexmedetomidine and paralytic exposure after damage control laparotomy: risk factors for delirium? Results from the EAST SLEEP-TIME multicenter trial. Eur J Trauma Emerg Surg 2021; 48:2097-2105. [PMID: 34807273 DOI: 10.1007/s00068-021-01813-x] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/12/2021] [Accepted: 10/25/2021] [Indexed: 10/19/2022]
Abstract
PURPOSE To evaluate factors associated with ICU delirium in patients who underwent damage control laparotomy (DCL), with the hypothesis that benzodiazepines and paralytic infusions would be associated with increased delirium risk. We also sought to evaluate the differences in sedation practices between trauma (T) and non-trauma (NT) patients. METHODS We reviewed retrospective data from 15 centers in the EAST SLEEP-TIME registry admitted from January 1, 2017 to December 31, 2018. We included all adults undergoing DCL, regardless of diagnosis, who had completed daily Richmond Agitation Sedation Score (RASS) and Confusion Assessment Method-ICU (CAM-ICU). We excluded patients younger than 18 years, pregnant women, prisoners and patients who died before the first re-laparotomy. Data collected included age, number of re-laparotomies after DCL, duration of paralytic infusion, duration and type of sedative and opioid infusions as well as daily CAM-ICU and RASS scores to analyze risk factors associated with the proportion of delirium-free/coma-free ICU days during the first 30 days (DF/CF-ICU-30) using multivariate linear regression. RESULTS A 353 patient subset (73.2% trauma) from the overall 567-patient cohort had complete daily RASS and CAM-ICU data. NT patients were older (58.9 ± 16.0 years vs 40.5 ± 17.0 years [p < 0.001]). Mean DF/CF-ICU-30 days was 73.7 ± 96.4% for the NT and 51.3 ± 38.7% in the T patients (p = 0.030). More T patients were exposed to Midazolam, 41.3% vs 20.3% (p = 0.002). More T patients were exposed to Propofol, 91.0% vs 71.9% (p < 0.001) with longer infusion times in T compared to NT (71.2 ± 85.9 vs 48.9 ± 69.8 h [p = 0.017]). Paralytic infusions were also used more in T compared to NT, 34.8% vs 18.2% (p < 0.001). Using linear regression, dexmedetomidine infusion and paralytic infusions were associated with decreases in DF/CF-ICU-30, (- 2.78 (95%CI [- 5.54, - 0.024], p = 0.040) and (- 7.08 ([- 13.0, - 1.10], p = 0.020) respectively. CONCLUSIONS Although the relationship between paralytic use and delirium is well-established, the observation that dexmedetomidine exposure is independently associated with increased delirium and coma is novel and bears further study.

Abstract
BACKGROUND Damage-control laparotomy (DCL) has been used for traumatic and nontraumatic indications. We studied factors associated with delirium and outcome in this population. METHODS We reviewed DCL patients at 15 centers for 2 years, including demographics, Charlson Comorbidity Index (CCI), diagnosis, operations, and outcomes. We compared 30-day mortality; renal failure requiring dialysis; number of takebacks; hospital, ventilator, and intensive care unit (ICU) days; and delirium-free and coma-free proportion of the first 30 ICU days (DF/CF-ICU-30) between trauma (T) and nontrauma (NT) patients. We performed linear regression for DF/CF-ICU-30, including age, sex, CCI, achievement of primary fascial closure (PFC), small and large bowel resection, bowel discontinuity, abdominal vascular procedures, and trauma as covariates. We performed one-way analysis of variance for DF/CF-ICU-30 against traumatic brain injury severity as measured by Abbreviated Injury Scale for the head. RESULTS Among 554 DCL patients (25.8% NT), NT patients were older (58.9 ± 15.8 vs. 39.7 ± 17.0 years, p < 0.001), more female (45.5% vs. 22.1%, p < 0.001), and had higher CCI (4.7 ± 3.3 vs. 1.1 ± 2.2, p < 0.001). The number of takebacks (1.7 ± 2.6 vs. 1.5 ± 1.2), time to first takeback (32.0 hours), duration of bowel discontinuity (47.0 hours), and time to PFC were similar (63.2 hours, achieved in 73.5%). Nontrauma and T patients had similar ventilator, ICU, and hospital days and mortality (31.0% NT, 29.8% T). Nontrauma patients had higher rates of renal failure requiring dialysis (36.6% vs. 14.1%, p < 0.001) and postoperative abdominal sepsis (40.1% vs. 17.1%, p < 0.001). Trauma and NT patients had similar number of hours of sedative (89.9 vs. 65.5 hours, p = 0.064) and opioid infusions (106.9 vs. 96.7 hours, p = 0.514), but T had lower DF/CF-ICU-30 (51.1% vs. 73.7%, p = 0.029), indicating more delirium. Linear regression analysis indicated that T was associated with a 32.1% decrease (95% CI, 14.6%-49.5%; p < 0.001) in DF/CF-ICU-30, while achieving PFC was associated with a 25.1% increase (95% CI, 10.2%-40.1%; p = 0.001) in DF/CFICU-30. Increasing Abbreviated Injury Scale for the head was associated with decreased DF/CF-ICU-30 by analysis of variance (p < 0.001). CONCLUSION Nontrauma patients had higher incidence of postoperative abdominal sepsis and need for dialysis, while T was independently associated with increased delirium, perhaps because of traumatic brain injury.

More medications, more problems: results from the Sedation Level after Emergent Exlap with Packing for TRAUMA (SLEEP-TRAUMA) study. Eur J Trauma Emerg Surg 2020; 48:943-952.

Abstract
Purpose Sedation management of trauma patients after damage control laparotomy (DCL) has not been optimized. We evaluated if shorter sedation exposure was associated with increased proportion of delirium-free/coma-free (DF/CF-ICU) days and change in time to definitive fascial closure (DFC). Methods We reviewed trauma DCL patients at an ACS-verified level I center over 5 years as shorter (SE) or longer than median (LE) sedation exposure. We compared demographics, injury patterns, hemodynamic parameters, and injury severity between groups. We calculated the propensity for each patient to achieve DFC using age, gender, ISS, red blood cell transfusion, bowel discontinuity, abdominal vascular injury, and time to first takeback; we then determined the effect of sedation exposure on rate of DFC by multivariate Cox regression, adjusted for propensity to achieve DFC. We used linear regression adjusted for age, ISS, head-AIS, bowel discontinuity, and vascular injury to determine the effect of sedation exposure on the proportion of DF/CF-ICU days. Results 65 patients (33.8% penetrating) had mean age 41.8 ± 16.0, ISS 27.1 ± 14.2, Head-AIS 1.2 ± 1.6 and median sedation exposure of 2.2 [IQR 0.78, 7.3] days (35 SE and 30 LE). Pattern and severity of solid organ injuries and proportion of small and large bowel and vascular injuries were similar between groups. LE had more abdominal sepsis (23.3% vs 0%, p = 0.003) and enterocutaneous fistula (16.7% vs 0%, p = 0.016), and more ventilator (17.3 ± 12.7 vs 6.1 ± 6.8, p < 0.001), ICU (20.8 ± 14.2 vs 7.2 ± 7.6, p < 0.001), and hospital days (29.6 ± 19.6 vs 13.9 ± 9.0, p < 0.001). DFC was achieved more rapidly in the SE group (2.0 ± 1.5 days vs 3.9 ± 3.7 days [unadjusted], p = 0.023) and SE had a higher proportion of unadjusted DF/CF-ICU days (33.0 ± 32.0% vs 18.1 ± 16.4%, p = 0.020). SE was associated with an increased proportion of adjusted DF/CF-ICU days by multivariate linear regression (13.1% [95% CI 1.4–24.8%], p = 0.029) and with faster adjusted rate of DFC by multivariate Cox regression (RR 2.28 [95% CI 1.25–4.15, p = 0.007]). Conclusions Shorter sedation exposure is associated with increased proportion of DF/CF-ICU days and more rapid DFC after DCL for trauma.

Abstract
BACKGROUND Patients with an open abdomen after trauma or emergency surgery may benefit from reduced sedation and chemical paralysis. We studied the effect of attending surgeon experience on sedation depth and paralytic use, as well as enteral nutrition and time between laparotomies. METHODS We performed an institutional review board-approved survey (Sedation Level after Emergent ExLap without Primary Fascial Closure) of the senior and active Eastern Association for the Surgery of Trauma membership using Qualtrics (Qualtrics, Inc, Provo, UT). We obtained 393/1,655 responses (23.7%). Spearman's rho was used for ordinal data, and multivariate logistic regression was used to adjust for trauma center level and presence of trainees in the relationship between surgeon experience and use of deep sedation. RESULTS Surgeon experience was associated with deep sedation (Richmond Agitation and Sedation Score ≤-3, P = .001) and chemical paralysis (P = .001). Surgeon experience was associated with less concern about delirium and more concern for evisceration as the reason for sedation depth (P = .001) and for paralysis (P = .001). Using multivariate logistic regression, surgeon experience was associated with deep sedation (odds ratio 3.6 [95% confidence interval 1.3, 10.4], P = .017 for ≥20 years; odds ratio 3.5 [95% confidence interval 1.1, 10.4], P = .025 for 15-20 years). Trauma center level was also significant (odds ratio 7.2 for Richmond Agitation and Sedation Score ≤-3 [95% confidence interval 1.7, 31.0], P = .008 for level III/IV versus level I/II). Increased surgeon experience was associated with delay of commencement of enteral feeds until return of bowel function (P = .013). Few respondents indicated willingness to extubate or mobilize open abdomen patients. Experienced surgeons were likely to wait for a defined time rather than for normalization of resuscitation markers to perform the first takeback laparotomy (P = .047) and waited longer between subsequent laparotomies (P = .004). CONCLUSION There were significant variations in practice among respondents based on the length of time since their last residency or fellowship, including variations that deviate from current best practice for management of patients with an open abdomen.

Abstract
The appropriate level of sedation in patients with an open abdomen following damage control laparotomy (DCL) is debated. Chemical paralysis with neuromuscular blocking agents (NMBAs) has been used to decrease time to abdominal closure. We sought to evaluate the effect of NMBA use on sedation requirements in patients with an open abdomen and to determine the effect of sedation on patient outcomes. A retrospective cohort study was conducted at an American College of Surgeons' verified level 1 trauma center. Adult trauma patients who underwent DCL between 2009 and 2015 were included. Patients with an intensive care unit length of stay of less than 48 hours and those who died before abdominal closure were excluded. The NMBA+ group received continuous NMBA within 24 hours of DCL; the NMBA- group did not. The primary outcome was cumulative sedation dose during the 7 days following DCL. Secondary outcomes included Richmond Agitation-Sedation Scale (RASS) score, mechanical ventilation-free days, and delirium-coma-free days. Delirium-coma-free days were analyzed with linear regression. A total of 222 patients were included (NMBA+ 125; NMBA- 97). Demographics were similar between groups including age, Injury Severity Score, and mechanism of injury. The median time to closure in the overall cohort was 2 days (interquartile range [IQR] 1-2 days). Propofol and fentanyl were the primary sedatives used. The NMBA+ group received higher cumulative doses of propofol (NMBA+ 5405 mg, IQR 3103-10,573 mg; NMBA- 3601 mg, IQR 1605-6887 mg; p=0.007), but not of fentanyl. Time to abdominal closure, but not NMBA use, was associated with a higher cumulative propofol dose on multivariate analysis. The NMBA+ group had significantly lower RASS scores on the first 3 days following DCL. Mechanical ventilation-free days (NMBA+ 20 days vs NMBA- 18 days, p=0.960) and delirium-coma-free days (NMBA+ 18 days vs NMBA- 18 days, p=0.610) were similar between the groups. On linear regression, cumulative propofol dose was associated with fewer delirium-coma-free days (β-coefficient -0.007, 95% confidence interval -0.015 to -0.003). In trauma patients managed with DCL, higher cumulative sedative doses were administered in patients who received adjunctive NMBA, although NMBA therapy was not associated with a higher cumulative propofol dose on multivariate analysis. Consideration must be given to the potential effect of sedation on delirium and awakening following DCL.
