The safety of continuous fascia iliaca block in patients with hip fracture taking pre-injury anticoagulant and/or antiplatelet medications.

BACKGROUND: Fascia iliaca compartment block (FICB) is an effective method to treat pain in adult trauma patients with hip fracture. Of importance is the high prevalence of preinjury anticoagulants and antiplatelet medications in this population. To date, we have not identified any literature that has specifically evaluated the safety of FICB with continuous catheter infusion in patients on antiplatelet and/or anticoagulant therapy. The purpose of this study is to quantify the complication rate associated with FICB in patients who are actively taking prescribed anticoagulant and/or antiplatelet medications prior to injury and identify factors that may predispose patients to an adverse event. METHODS: This retrospective study included consecutive adult trauma patients (age ≥18) with hip fracture who underwent placement of FICB within 24 h of admission and had been taking anticoagulant and/or antiplatelet medications pre-injury. Patients were excluded if their catheter was placed more than 24 h post-hospital admission. Patients were evaluated for demographics, injury severity, laboratory values, medication history, receipt of coagulation-related reversal medications, and complications related to FICB placement. Complications included bleeding at the insertion site requiring catheter removal and 30-day catheter site infection. The incidence of complications was reported and risk factors for complications were identified using univariate and multivariate statistics. RESULTS: There were 124 patients included. The mean age was 81 ± 10 years, and the most common mechanism was ground level fall (94%). Most patients were taking single antiplatelet therapy (65%), followed by anticoagulant alone (21%), combined antiplatelet and anticoagulant therapy (7.3%) and dual antiplatelet therapy (7.3%). The most common antiplatelet was aspirin (88%) and the most common anticoagulant was warfarin (60%). Of the patients taking warfarin, the average INR on admission was 2.3 ± 0.8. Only 1 bleeding complication (0.8%) was noted in a patient prescribed clopidogrel pre-injury which occurred 5 days post-catheter placement. This same patient was noted to have superficial surgical site bleeding most likely secondary to the use of enoxaparin for post-operative deep venous thrombosis prophylaxis. There were 4 orthopedic superficial surgical site infections (3.2%), all remote from the catheter site. The pre-injury medication prescribed in these patients was aspirin 81 mg, aspirin 325 mg, rivaroxaban and dabigatran, respectively. No factors were associated with a complication thus multivariate analysis was not performed. CONCLUSION: The incidence of complications associated with fascia iliaca compartment block (FICB) in adult trauma patients prescribed pre-injury anticoagulants or antiplatelet medications is low. In this retrospective review, we did not identify any complications that were directly associated with the FICB procedure. Fascia iliaca block with continuous infusion catheter placement can be safely performed on patients who are on therapeutic anticoagulant and/or antiplatelet agents.

N -acetylcysteine is associated with reduction of postconcussive symptoms in elderly patients: A pilot study.

INTRODUCTION: N -acetylcysteine (NAC) may be neuroprotective by minimizing postconcussion symptoms after mild traumatic brain injury (TBI), but limited data exist. This study evaluated the effects of NAC on postconcussion symptoms in elderly patients diagnosed with mild TBI. METHODS: This prospective, quasirandomized, controlled trial enrolled patients 60 years or older who suffered mild TBI. Patients were excluded if cognitive function could not be assessed within 3-hours postinjury. Patients were allocated to receive NAC plus standard care, or standard care alone, based on the trauma center where they presented. The primary study outcome was the severity of concussive symptoms measured using the Rivermeade Postconcussion Symptoms Questionnaire (RPQ). Symptoms were evaluated on days 0, 7, and 30. The RPQ scores were compared both within and between treatment groups. RESULTS: There were 65 patients analyzed (NAC, n = 34; control, n = 31) with an average age of 76 ± 10 years. Baseline demographics and clinical variables were similar. No group differences in head Abbreviated Injury Scale score or Glasgow Coma Scale score were observed. Baseline RPQ scores (6 [0-20] vs. 11 [4-20], p = 0.300) were indistinguishable. The RPQ scores on day 7 (2 [0-8] vs. 10 [3-18], p = 0.004) and 30 (0 [0-4] vs. 4 [0-13], p = 0.021) were significantly lower in the NAC group. Within-group differences were significantly lower in the NAC ( p < 0.001) but not control group ( p = 0.319). CONCLUSION: N -acetylcysteine was associated with significant improvements in concussion symptoms in elderly patients with mild TBI. These results justify further research into using NAC to treat TBI. LEVEL OF EVIDENCE: Therapeutic/Care Management; Level IV.

The Role of Desmopressin on Hematoma Expansion in Patients with Mild Traumatic Brain Injury Prescribed Pre-injury Antiplatelet Medications.

BACKGROUND/OBJECTIVE: Desmopressin (DDAVP) has been suggested for antiplatelet medication reversal in patients with traumatic brain injury (TBI) but there are limited data describing its effect on clinical outcomes. The purpose of this study was to evaluate the effect of DDAVP on hematoma expansion and thrombosis in patients with TBI who were prescribed pre-injury antiplatelet medications. METHODS: Consecutive adult patients who were admitted to our level I trauma center and prescribed pre-injury antiplatelet medications between July, 2012, and May, 2018, were retrospectively identified. Patients were excluded if their hospital length of stay was < 24 h, if DDAVP was administered by any route other than intravenous, if they received a DDAVP dose < 0.3 mcg/kg or there was no evidence of brain hemorrhage on computed tomography (CT) scan. Patients were stratified based on the use of DDAVP, and the incidence of hematoma expansion was compared between groups. Thrombotic events were reviewed as a secondary outcome. Multivariate analysis was utilized to control for confounding variables. RESULTS: Of 202 patients included in analysis, 158 (78%) received DDAVP. The mean age was 76 ± 12 years; the most common injury mechanism was falls (76%); 69% had acute subdural hematoma, and 49% had multi-compartmental hemorrhage. Initial Glasgow coma score was between 13 and 15 for 91% of patients. Aspirin was the most common antiplatelet regimen prescribed (N = 151, 75%), followed by dual antiplatelet regimens (N = 26, 13%) and adenosine diphosphate (ADP)-receptor inhibitors (N = 25, 12%). The incidence of hematoma expansion was 14% and 30% for patients who did and did not receive DDAVP, respectively (p = 0.015). After controlling for age, injury severity score, multi-compartmental hemorrhage, and receipt of pre-injury high-dose aspirin (> 81 mg), ADP-receptor inhibitors, oral anticoagulants, prothrombin complex concentrates or platelets in a multivariate analysis, the association between DDAVP and hematoma expansion remained significant (adjusted OR 0.259 [95% CI 0.103-0.646], p = 0.004). Thrombotic events were similar between the two groups (DDAVP, 2.5%, no DDAVP, 4.5%; p = 0.613). CONCLUSIONS: DDAVP was associated with a lower incidence of hematoma expansion in patients with mild TBI who were prescribed pre-injury antiplatelet medications. These results justify a randomized controlled trial to further evaluate the role of DDAVP for this indication.

Utilization of Augmented Renal Clearance in Trauma Intensive Care Scoring System to Improve Vancomycin Dosing in Trauma Patients at Risk for Augmented Renal Clearance.

Background: The Augmented Renal Clearance in Trauma Intensive Care (ARCTIC) scoring system is a validated system to predict augmented renal clearance in trauma patients. This study examined the ability of the ARCTIC score to identify patients at risk for subtherapeutic vancomycin trough concentrations relative to estimated creatinine clearance (eCrCl) alone. Methods: Trauma patients admitted to the intensive care unit from September 2012 to December 2017 who received vancomycin and had a vancomycin trough concentration recorded were included. Patients were excluded if their serum creatinine concentration was >1.3 mg/dL, if they had received vancomycin doses <30 mg/kg per day, an improperly timed trough concentration measurement, or renal replacement therapy. The primary endpoint was an initial subtherapeutic vancomycin trough concentration (<10 mg/L). Classification and regression tree (CART) analysis was used to identify thresholds for the ARCTIC score and other continuous data where subtherapeutic troughs were more common. A step-wise logistic regression analysis was performed to control for confounders for subtherapeutic troughs whereby inclusion of ARCTIC was modeled sequentially after eCrCl. Results: A total of 119 patients with a mean age of 42 ± 17 years and eCrCl 142 ± 39 mL/min met the inclusion criteria. The mean daily vancomycin dose was 44 ± 9 mg/kg, and the incidence of subtherapeutic trough concentration was 46%. The CART analysis identified two variables creating three groups where subtherapeutic trough concentrations differed: eCrCl >105 mL/min and ARCTIC score ≥7, eCrCl >105 mL/min and ARCTIC score <7, and eCrCl ≤105 mL/min. The base logistic regression model identified eCrCl >105 mL/min and pelvic fracture as risk factors for subtherapeutic trough values. The final model included the addition of ARCTIC score ≥7, which improved the model significantly (p = 0.009). Predictors of subtherapeutic trough concentrations were (odds ratio [95% confidence interval]): eCrCl >105 mL/min (6.5 [1.66-25.07]), ARCTIC score ≥7 (3.26 [1.31-8.09]), and pelvic fracture (4.36 [1.27-14.93]). Conclusion: The ARCTIC score is useful when applied in conjunction with eCrCl. Patients with a eCrCl >105 mL/min and an ARCTIC score ≥7 may require a more aggressive dosing strategy.

Utilization of Geriatric Consultation and Team-Based Care.

Geriatric surgical patients experience higher mortality and morbidity rates than their younger counterparts. Three models of geriatric surgical care are described, with a focus on people, plans, and evaluation. These models include geriatric consultation services, geriatric wards, and geriatric multidisciplinary teams. The optimal care plan should be definitive, aggressive, sustainable, safe, and effective, with consideration for patient treatment preferences and wishes.

Lacosamide versus phenytoin for the prevention of early post traumatic seizures.

PURPOSE: To compare the efficacy and safety of lacosamide versus phenytoin for seizure prophylaxis following TBI. MATERIALS AND METHODS: All TBI patients who received prophylaxis with either phenytoin or lacosamide were retrospectively identified. The incidence of seizures within the first 7 days of injury were compared along with adverse effects requiring drug discontinuation. A planned sub-group analysis was performed for patients with severe TBI (GCS < 9). RESULTS: There were 481 patients (phenytoin, n = 116; lacosamide, n = 365). Demographics were similar but age (50 ±â€¯21 vs 58 ±â€¯22 years, P < .001) and initial GCS (11.3 ±â€¯4.3 vs 12.5 ±â€¯3.8, P = .010) were lower in the phenytoin group. The need for mechanical ventilation was higher (53% vs 38%, P = .004). Seizures occurred in 0.9% of the phenytoin group and 1.4% of the lacosamide group (P = 1.00). ADEs were significantly higher with phenytoin (5.2% vs 0.5%, P = .003). This difference remained significant upon multivariate analysis [OR(95% CI) = 9.4(1.8-48.9)]. Subgroup analysis for patients with severe TBI revealed no difference in seizures (phenytoin, 0% vs lacosamide, 1.5%; P = 1.00) but more ADEs with phenytoin (12.5% vs 0%, P = .010). CONCLUSION: There was no difference between lacosamide and phenytoin in the prevention of early post traumatic seizures in patients following TBI. Lacosamide may have a more tolerable side effect profile.

Bilateral Pneumothoraces in a Trauma Patient After Dobhoff Tube Insertion.

BACKGROUND Dobhoff tube insertion is a common procedure used in the clinical setting to deliver enteral nutrition. Although it is often viewed as an innocuous bedside procedure, there are risks for numerous complications such as tracheobronchial insertion, which could lead to deleterious consequences. We present to our knowledge the first reported case of bilateral pneumothoraces caused by the insertion of a Dobhoff tube. In addition, we also discuss common pitfalls for confirming the positioning of Dobhoff tubes, as well as risk factors that can predispose a patient to improper tube placement. CASE REPORT We present the case of a 74-year-old male patient with multiple orthopedic injuries following an auto-pedestrian collision. Five attempts were made to place a Dobhoff tube to maintain enteral nutrition. Follow-up abdominal x-ray revealed displacement of the Dobhoff tube in the left pleural space. After removal of the tube, a follow-up chest x-ray revealed iatrogenic bilateral pneumothoraces. Acute hypoxemic respiratory failure ensued; therefore, bilateral chest tubes were placed. Over the next three weeks, the patient's respiratory status improved and both chest tubes were removed. The patient was eventually discharged to a skilled nursing facility. CONCLUSIONS Improper placement of Dobhoff tubes can lead to rare complications such as bilateral pneumothoraces. This unique case report of bilateral pneumothoraces after Dobhoff tube placement emphasizes the necessity of using proper diagnostic techniques for verifying proper tube placement, as well as understanding the risk factors that predispose a patient to a malpositioned tube.

Geriatric (G60) trauma patients with severe rib fractures: Is muscle sparing minimally invasive thoracotomy rib fixation safe and does it improve post-operative pulmonary function?

BACKGROUND: Patient outcomes after muscle sparing minimally invasive thoracotomy rib fixation (MSMIT-ORF) in geriatric G60 trauma patients remain poorly studied. This study determined the effect of MSMIT-ORF on pulmonary function (PFT). Non-operatively managed (NOM) patients were also described. METHODS: Medical records of G60 patients with severe rib fractures with PFTs measured before and after MSMIT-ORF were examined. Patient outcomes (MSMIT-ORF vs NOM) were adjusted in a multivariate logistic regression model. RESULTS: 64 patients underwent MSMIT-ORF, 135 were NOM patients. MSMIT-ORF treated patients showed improvements in PFTs on postoperative day 5, p = 0.001. After adjustment analysis, MSMIT-ORF was associated with increased hospital length of stay (OR 44.9; 95% CI, 9.8-205, p < 0.001), but a more favorable discharge disposition. There was no difference in the rates of pneumonia (p = 0.996) or death (p = 0.140). CONCLUSIONS: MSMIT-ORF is safe and improves pulmonary function in G60 trauma patients diagnosed with severe rib fractures. Future randomized control studies are needed for confirmation.

Identifying augmented renal clearance in trauma patients: Validation of the Augmented Renal Clearance in Trauma Intensive Care scoring system.

BACKGROUND: Augmented renal clearance (ARC) is common in trauma patients and associated with subtherapeutic antimicrobial concentrations. This study reported the incidence of ARC, identified ARC risk factors, and described a model to predict ARC (i.e., ARCTIC) that is specific to trauma patients. METHODS: Consecutive trauma patients who were admitted to the intensive care unit between March 2015 and January 2016 and had a measured creatinine clearance (CrCl) were considered for inclusion. Patients were excluded if their serum creatinine (SCr) was greater than 1.3 mg/dL. ARC was defined as a measured CrCl of 130 mL/min or greater. Demographic and trauma-specific variables were then compared, and multivariate analysis was performed. Using these results, a weighted scoring system was constructed and evaluated using receiver operating characteristic curve analysis. ARCTIC score cutoffs were chosen based on sensitivity, specificity, positive predictive value, and negative predictive value. The derived scoring system was then compared to a previously published scoring system for accuracy. RESULTS: There were 133 patients with a mean age of 48 ± 19 years and SCr of 0.8 ± 0.2 mg/dL. The mean measured CrCl was 168 ± 65 mL/min, and the incidence of ARC was 67%. Multivariate analysis revealed the following risk factors for ARC (age, <56: odds ratios [OR], 58.3; 95% confidence interval [CI], 5.2-658.9; age, 56 to 75: OR, 13.5; 95% CI, 1.2-151.7), SCr less than 0.7 mg/dL (OR, 12.5; 95% CI, 3-52.6), and male sex (OR, 6.9; 95% CI, 1.9-24.9). Using these results, the ARCTIC scoring system was: 4 points if younger than 56 years, 3 points if aged 56 years to 75 years, 3 points if SCr less than 0.7 mg/dL, and 2 points if male sex. Receiver operating characteristic curve analysis revealed an area (95% CI) of 0.813 (0.735-0.892) (p < 0.001). An ARCTIC score of 6 or higher had a sensitivity, specificity, positive predictive value, and negative predictive value of 0.843, 0.682, 0.843, and 0.682, respectively. CONCLUSION: The incidence of ARC in trauma patients is high. The ARCTIC score represents a practical, pragmatic system that can be easily applied at the bedside. An ARCTIC score of 6 or higher represents an appropriate cutoff to screen for ARC where antimicrobial adjustments should be considered. LEVEL OF EVIDENCE: Prognostic/epidemiologic study, level III.

The importance of empiric antibiotic dosing in critically ill trauma patients: Are we under-dosing based on augmented renal clearance and inaccurate renal clearance estimates?

BACKGROUND: An accurate assessment of creatinine clearance (CrCl) is essential when dosing medications in critically ill trauma patients. Trauma patients are known to experience augmented renal clearance (i.e., CrCl ≥130 mL/min), and the use of CrCl estimations may be inaccurate leading to under-/over-dosing of medications. As such, our Level I trauma center began using measured CrCl from timed urine collections to better assess CrCl. This study sought to determine the prevalence of augmented renal clearance and the accuracy of calculated CrCl in critically ill trauma patients. METHODS: This observational study evaluated consecutive ICU trauma patients with a timed 12-hour urine collection for CrCl. Data abstracted were patient demographics, trauma-related factors, and CrCl. Augmented renal clearance was defined as measured CrCl ≥130 mL/min. Bias and accuracy were determined by comparing measured and estimated CrCl using the Cockcroft-Gault and other formulas. Bias was defined as measured minus calculated CrCl, and accuracy was calculated CrCl that was within 30% of measured. RESULTS: There were 65 patients with a mean age of 48 years, serum creatinine (SCr) of 0.8 ± 0.3 mg/dL, and injury severity score of 22 ± 14. The incidence of augmented renal clearance was 69% and was more common when age was <67 years and SCr <0.8 mg/dL. Calculated CrCl was significantly lower than measured (131 ± 45 mL/min vs. 169 ± 70 mL/min, p < 0.001) and only moderately correlated (r = 0.610, p < 0.001). Bias was 38 ± 56 mL/min, which was independent of age quartile (p = 0.731). Calculated CrCl was inaccurate in 33% of patients and trauma-related factors were not predictive. CONCLUSION: The prevalence of augmented renal clearance in critically ill trauma patients is high. Formulas used to estimate CrCl in this population are inaccurate and could lead to under-dosing of medications. Measured CrCl should be used in this setting to identify augmented renal clearance and allow for more accurate estimates of renal function. LEVEL OF EVIDENCE: Prognostic/epidemiologic study, level III.

Is there a difference in efficacy, safety, and cost-effectiveness between 3-factor and 4-factor prothrombin complex concentrates among trauma patients on oral anticoagulants?

PURPOSE: The aim of this study was to compare the efficacy, safety, and cost-effectiveness of 3-factor prothrombin complex concentrate (3F-PCC) vs 4-factor prothrombin complex concentrate PCC (4F-PCC) in trauma patients requiring reversal of oral anticoagulants. MATERIALS AND METHODS: All consecutive trauma patients with coagulopathy (international normalized ratio [INR] ≥1.5) secondary to oral anticoagulants who received either 3F-PCC or 4F-PCC from 2010 to 2014 at 2 trauma centers were reviewed. Efficacy was determined by assessing the first INR post-PCC administration, and successful reversal was defined as INR less than 1.5. Safety was assessed by reviewing thromboembolic events, and cost-effectiveness was calculated using total treatment costs (drug acquisition plus transfusion costs) per successful reversal. RESULTS: Forty-six patients received 3F-PCC, and 18 received 4F-PCC. Baseline INR was similar for 3F-PCC and 4F-PCC patients (3.1 ± 2.3 vs 3.4 ± 3.7, P = .520). The initial PCC dose was 29 ± 9 U/kg for 3F-PCC and 26 ± 6 U/kg for 4F-PCC (P = .102). The follow-up INR was 1.6 ± 0.6 for 3F-PCC and 1.3 ± 0.2 for 4F-PCC (P = .001). Successful reversal rates in patients were 83% for 4F-PCC and 50% for 3F-PCC (P = .022). Thromboembolic events were observed in 15% of patients with 3F-PCC vs 0% with 4F-PCC (P = .177). Cost-effectiveness favored 4F-PCC ($5382 vs $3797). CONCLUSIONS: Three-factor PCC and 4F-PCC were both safe in correcting INR, but 4F-PCC was more effective, leading to better cost-effectiveness. Replacing 3F-PCC with 4F-PCC for urgent coagulopathy reversal may benefit patients and institutions.

Geriatric trauma G-60 falls with hip fractures: A pilot study of acute pain management using femoral nerve fascia iliac blocks.

BACKGROUND: Hip fractures due to falls cause significant morbidity and mortality among geriatric patients. A significant unmet need is an optimal pain management strategy. Consequently, patients are treated with standard analgesic care (SAC) regimens, which deliver high narcotic doses. However, narcotics are associated with delirium as well as gastrointestinal and respiratory failure risks. The purpose of this pilot study was to determine the safety and effectiveness of ultrasound-guided continuous compartmental fascia iliaca block (CFIB) in patients 60 years or older with hip fractures in comparison with SAC alone. METHODS: We performed a retrospective study of 108 patients 60 years or older, with acute pain secondary to hip fracture (2012-2013). Patient variables were age, sex, comorbidities, and Injury Severity Score (ISS). Primary outcome was pain scores; secondary outcomes included hospital length of stay, discharge disposition, morbidity, and mortality. Statistical analysis was performed using (IBM SPSS version 22). For group comparison (SAC vs. SAC + CFIB) median test, repeated-measures analysis and Student's t test of transformed pain scores were used. RESULTS: Sixty-four patients received SAC only, and 44 patients received SAC + CFIB. Each CFIB placement was successful on first attempt without complications. Median time from emergency department arrival to block placement was 12.5 hours (interquartile range, 4-22 hours). Patients who received SAC + CFIB had significantly lower pain score ratings than patients treated with SAC alone. There were no differences in inpatient morbidity and mortality rates. Patients treated with SAC + CFIB were discharged home more often (p < 0.05). CONCLUSION: Ultrasound-guided CFIB is safe, practical, and readily integrated into the G-60 service for improved pain management of hip fractures. We are now conducting a prospective randomized control trial to confirm our observations. LEVEL OF EVIDENCE: Therapeutic study, level IV.

Trauma-associated pneumonia: time to redefine ventilator-associated pneumonia in trauma patients.

BACKGROUND: The high prevalence of ventilator-associated pneumonia (VAP) in trauma patients has been reported in the literature, but the reasons for this observation remain unclear. We hypothesize that trauma factors play critical roles in VAP etiology. METHODS: In this retrospective study, 1,044 ventilated trauma patients were identified from December 2010 to December 2013. Patient-level trauma factors were used to predict pneumonia as study endpoint. RESULTS: Ninety-five of the 1,044 ventilated trauma patients developed pneumonia. Rib fractures, pulmonary contusion, and failed prehospital intubation were significant predictors of pneumonia in a multivariate model. CONCLUSIONS: It is time to redefine VAP in trauma patients based on the effect of rib fractures, pulmonary contusions, and failed prehospital intubations. The Centers for Disease Control and Prevention definition of VAP needs to be modified to reflect the effect of trauma factors in the etiology of trauma-associated pneumonia.

Geriatric trauma hip fractures: is there a difference in outcomes based on fracture patterns?

BACKGROUND: Annually in the US, there are over 300,000 hospital admissions due to hip fractures in geriatric patients. Consequently, there have been several large observational studies, which continue to provide new insights into differences in outcomes among hip fracture patients. However, few hip fracture studies have specifically examined the relationship between hip fracture patterns, sex, and short-term outcomes including hospital length of stay and discharge disposition in geriatric trauma patients. METHODS: We performed a retrospective study of hip fractures in geriatric trauma patients. Hip fracture patterns were based on ICD -9 CM diagnostic codes for hip fractures (820.00-820.9). Patient variables were patient demographics, mechanism of injury, injury severity score, hospital and ICU length of stay, co-morbidities, injury location, discharge disposition, and in-patient mortality. RESULTS: A total of 325 patient records met the inclusion criteria. The mean age of the patients was 82.2 years, and the majority of the patients were white (94%) and female (70%). Hip fractures patterns were categorized as two fracture classes and three fracture types. We observed a difference in the proportion of males to females within each fracture class (Femoral neck fractures Z-score = -8.86, p < 0.001, trochanteric fractures Z-score = -5.63, p < 0.001). Hip fractures were fixed based on fracture pattern and patient characteristics. Hip fracture class or fracture type did not predict short-term outcomes such as in-hospital or ICU length of stay, death, or patient discharge disposition. The majority of patients (73%) were injured at home. However, 84% of the patients were discharged to skilled nursing facility, rehabilitation, or long-term care while only 16% were discharged home. There was no evidence of significant association between fracture pattern, injury severity score, diabetes mellitus, hypertension or dementia. CONCLUSIONS: Hip fracture patterns differ between geriatric male and female trauma patients. However, there was no significant association between fracture patterns and short-term patient outcomes. Further studies are planned to investigate the effect of fracture pattern and long-term outcomes including 90-day mortality, return to previous levels of activity, and other quality of life measures.

Preperitoneal surgery using a self-adhesive mesh for inguinal hernia repair.

BACKGROUND AND OBJECTIVES: Laparoscopic preperitoneal hernia repair with mesh has been reported to result in improved patient outcomes. However, there are few published data on the use of a totally extraperitoneal (TEP) approach. The purpose of this study was to present our experience and evaluate early outcomes of TEP inguinal hernia repair with self-adhesive mesh. METHODS: This cohort study was a retrospective review of patients who underwent laparoscopic TEP inguinal hernial repair from April 4, 2010, through July 22, 2014. Data assessed were age, sex, body mass index (BMI), hernia repair indications, hernia type, pain, paresthesia, occurrence (bilateral or unilateral), recurrence, and patient satisfaction. Descriptive and regression analyses were performed. RESULTS: Six hundred forty patients underwent laparoscopic preperitoneal hernia surgery with self-adhesive mesh. The average age was 56 years, nearly all were men (95.8%), and the mean BMI was 26.2 kg/m(2). Cases involved primary hernia more frequently than recurrent hernia (94% vs 6%; P < .05). After surgery, 92% of the patients reported no more than minimal pain, <1% reported paresthesia, and 0.2% had early recurrence. There were 7 conversions to an open procedure. The patients had no adverse reactions to anesthesia and no bladder injury. Postoperative acute pain or recurrence was not explained by demographics, BMI, or preoperative pain. There were significant associations of hernia side, recurrence, occurrence, and sex with composite end points. Nearly all patients (98%) were satisfied with the outcome. CONCLUSION: The use of self-adhesive, Velcro-type mesh in laparoscopic TEP inguinal hernia repair is associated with reduced pain; low rates of early recurrence, infection, and hematoma; and improved patient satisfaction.
