Beyond the short-term relief: Outcomes of geriatric rib fracture patients receiving paravertebral nerve blocks and epidural analgesia

BACKGROUND

Adequate pain control is a critical component of rib fracture management. Our study aimed to evaluate the in-hospital and post-discharge outcomes of geriatric rib fracture patients who received paravertebral nerve block (PVNB) versus epidural analgesia (EA) on a national level.

METHODS

We performed a 5-year (2011-15) retrospective analysis of the Nationwide Readmission database. We included all the geriatric (≥65 years) blunt trauma patients with rib fractures who received a paravertebral nerve block (PVNB) or Epidural analgesia (EA) for chest injuries. We excluded patients who were dead on arrival, those with head AIS≥3, spine AIS >0, and those with cognitive impairment. Patients were stratified into two groups (PVNB and EA). A propensity score matching (1:2) was performed, and the two groups were compared. Our outcomes included delirium, hospital length of stay (LOS), 90-day readmissions, 90-day mechanical ventilation, and initial and 90-day mortality.

RESULTS

A total of 2,855 geriatric rib fracture patients were identified, out of which 352 (12 %) received PVNB and 2,503 (87 %) received EA. The mean (SD) age was 78 (8) years and 53 % were female. A total of 1,041 patients were matched (PVNB=347, EA=694 patients). The median [IQR] Injury severity score was 9 [3-15], median chest AIS was 3 [2-4], and 70 % had ≥3 rib fractures. The total mortality during index admission was 6 %, 13 % experienced delirium, and the median hospital LOS was 6 [4-10] days. There was no difference in the primary outcomes of the two groups including rates of index admission mortality (PVNB: 5.2% vs. EA:6.3 %, p = 0.548) and delirium (PVNB: 12.4% vs. EA:12.9 %, p = 0.862). We also found no statistically significant difference between these groups in terms of 90-day respiratory complications (p = 1.000), 90-day readmission (p = 0.111), 90-day mortality (p = 0.718), and 90-day need for mechanical ventilation (p = 1.000).

CONCLUSION

The use of PVNB in geriatric trauma patients with multiple rib fractures is associated with comparable in-hospital and post-discharge outcomes relative to EA. PVNB is relatively easy to perform and has a better side effect profile. The use of PVNB as part of rib fracture management protocols warrants further consideration.

Inadequate Venous Thromboembolism Chemoprophylaxis Is Associated With Higher Venous Thromboembolism Rates Among Trauma Patients With Epidurals

INTRODUCTION

Guidelines encourage higher doses of low molecular weight heparin (LMWH) for prophylaxis in trauma patients. The risks of LMWH must be considered for patients who require an epidural catheter. We compared adequate and inadequate prophylaxis to determine if venous thromboembolism (VTE) and complication rates differed among patients with epidural catheters.

METHODS

Trauma patients who required an epidural catheter between 2012 and 2019 were reviewed for VTE and epidural-related complications. Adequate dosing was defined as enoxaparin 30 mg or 40 mg twice daily. Inadequate dosing was defined as unfractionated heparin subcutaneously or enoxaparin once daily.

RESULTS

Over the 8-y study period, 113 trauma patients required an epidural catheter of which 64.6% were males with a mean age of 55.8 y and injury severity score of 14. Epidural catheters were associated with 11 (9.7%) patients developing an acute deep vein thrombosis (DVT) and 2 (1.8%) patients with an acute pulmonary embolism. Those patients who received adequate doses of enoxaparin were less likely to have any VTE or DVT. Complications associated with epidural catheters were not dependent on the type of pharmacological prophylaxis.

CONCLUSIONS

Given the high VTE rate observed in trauma patients who required an epidural catheter, along with the low complication rate that was observed independent of the type of pharmacological prophylaxis given, the data indicate that current efforts for higher doses of LMWH appear to be safe and associated with a lower VTE rate.

Comparison of safety and efficacy of thoracic epidural block and erector spinae plane block for analgesia in patients with multiple rib fractures: A pilot single-blinded, randomised controlled trial

Background and Aims

Pain associated with rib fractures is challenging to manage. This pilot trial aimed to assess the efficacy of erector spinae plane block (ESPB) compared with thoracic epidural analgesia (TEA) for controlling pain associated with multiple rib fractures.

Methods

This randomised, single-blinded, controlled pilot study was conducted on trauma patients who had three or more rib fractures and had been admitted at a tertiary care centre. The study was conducted after receiving ethical approval and trial registration. Patients were randomised into two groups: TEA and ESPB, from February 2019 to February 2020. In the ESPB group, a unilateral or bilateral catheter was inserted in the erector spinae space, and an infusion of 0.125% bupivacaine was started. In the TEA group, the thoracic epidural catheter was inserted, and 0.125% bupivacaine infusion was started. Rescue analgesia using intravenous morphine (0.1 mg/kg) was administered if the Visual Analogue Scale (VAS) score was >3 for 48 hours postoperatively. The primary endpoint was total morphine consumption after administration of ESPB and TEA in patients with a rib fracture.

Results

Forty patients completed the study, with 20 in each group. Total morphine consumption by patients in the ESPB group was 5.38 ± 2.6 mg per 48 hours, and by those in the TEA group was 5.22 ± 2.11 mg per 48 hours (P = 0.883). Thirty minutes after starting the infusion, mean arterial pressure (MAP) was 64.8 ± 2.1 mmHg in the ESPB group and 57.2 ± 1.3 mmHg in the TEA group (P = 0.00001).

Conclusion

Total morphine consumption was not statistically different in this pilot trial among the two groups. ESP block may provide similar analgesia with better haemodynamic stability compared to TEA in patients with multiple traumatic rib fractures.

Ultrasound guided erector spinae plane block versus thoracic epidural analgesia in traumatic flail chest, a prospective randomized trial

Background and Aims

Pain contributes to flail chest morbidities. The aim of this study was to compare the analgesic effects of ultrasound-guided erector spinae plane block (ESPB) with thoracic epidural analgesia (TEA) in patients with traumatic flail chest.

Material and Methods

Sixty patients aged 18 - 60 years, ASA I-II, with unilateral flail chest were allocated into TEA group with a loading dose of 6 ml bupivacaine 0.25% and 2 μg/ml fentanyl and ESPB group with a loading dose of 20 ml bupivacaine 0.25% and 2 μg/ml fentanyl. This was followed by continuous infusion of 6 ml/hour bupivacaine 0.125% and 2 μg/ml fentanyl in both groups for 4 days. Pain scores at rest and on coughing, rescue analgesic consumption, PaO2/FIO2 ratio, PaCO2, pulmonary functions and adverse events were recorded.

Results

In both groups, Visual Analog Scale (VAS) scores at rest and on coughing were significantly decreased after block initiation as compared to pre-block value. At all-time points, VAS scores at rest and on coughing were insignificantly different between both groups. PaO2/FIO2 ratio, forced vital capacity (FVC) and forced expiratory volume in 1 second (FEV1) were significantly increased and respiratory rate, PaCO2, were significantly decreased as compared to pre-block values of the same group without significant difference between both groups. The incidence of hypotension was significantly higher in TEA group than ESPB group.

Conclusions

ESPB can achieve adequate analgesia in traumatic flail chest equivalent to that of TEA with significant improvement of arterial oxygenation and pulmonary functions and without serious adverse effects.

Non-surgical management and analgesia strategies for older adults with multiple rib fractures: A systematic review, meta-analysis, and joint practice management guideline from the Eastern Association for the Surgery of Trauma and the Chest Wall Injury Society

BACKGROUND

Chest wall injury in older adults is a significant cause of morbidity and mortality. Optimal nonsurgical management strategies for these patients have not been fully defined regarding level of care, incentive spirometry (IS), noninvasive positive pressure ventilation (NIPPV), and the use of ketamine, epidural, and other locoregional approaches to analgesia.

METHODS

Relevant questions regarding older patients with significant chest wall injury with patient population(s), intervention(s), comparison(s), and appropriate selected outcomes were chosen. These focused on intensive care unit (ICU) admission, IS, NIPPV, and analgesia including ketamine, epidural analgesia, and locoregional nerve blocks. A systematic literature search and review were conducted, our data were analyzed qualitatively and quantitatively, and the quality of evidence was assessed per the Grading of Recommendations Assessment, Development, and Evaluation methodology. No funding was used.

RESULTS

Our literature review (PROSPERO 2020-CRD42020201241, MEDLINE, EMBASE, Cochrane, Web of Science, January 15, 2020) resulted in 151 studies. Intensive care unit admission was qualitatively not superior for any defined cohort other than by clinical assessment. Poor IS performance was associated with prolonged hospital length of stay, pulmonary complications, and unplanned ICU admission. Noninvasive positive pressure ventilation was associated with 85% reduction in odds of pneumonia ( p < 0.0001) and 81% reduction in odds of mortality ( p = 0.03) in suitable patients without risk of airway loss. Ketamine use demonstrated no significant reduction in pain score but a trend toward reduced opioid use. Epidural and other locoregional analgesia techniques did not affect pneumonia, length of mechanical ventilation, hospital length of stay, or mortality.

CONCLUSION

We do not recommend for or against routine ICU admission. We recommend use of IS to inform ICU status and conditionally recommend use of NIPPV in patients without risk of airway loss. We offer no recommendation for or against ketamine, epidural, or other locoregional analgesia.

Erector Spinae Plane Blocks for Traumatic Rib Fractures: A Prospective, Interventional Study

BACKGROUND

Rib fractures are present in 10% of all trauma patients and 30% of patients with significant chest trauma. Pain from rib fractures results in decreased respiratory effort which can lead to atelectasis and potentially pneumonia and death. Pain control is therefore of utmost importance in preventing the complications of rib fractures by improving respiratory function. Erector spinae plane blocks (ESPB) have been effectively used in elective surgery with subjective and objective improvements in pain.

MATERIALS AND METHODS

We sought to evaluate subjective pain and objective evaluation of respiratory effort by way of incentive spirometry levels after administration of an ESPB for patients with rib fractures. Our trauma service applied ESPB over 2 years in patients with rib fractures. Ultrasound guidance was used to administer 50cc of a long-acting local anesthetic at the transverse process underneath the erector spinae muscle group. Evaluation of pain scores and incentive spirometry levels were measured prior to and after the ESPB.

RESULTS

In total, we obtained data from 45 patients. Mean pre-pain scores were 7.93 with post-pain scores of 4.47 (p < 0.001). Mean pre-block incentive spirometry volumes were 1160 cc with post-block IS of 1495cc (p 0.035). There were no associated complications.

DISCUSSION

ESPBs are safe and significantly reduce pain scores and increased incentive spirometry volumes after administration. They are easy to perform and can be done by the trauma service, including trainees. ESPB has the potential to reduce pulmonary complications of rib fractures, as well as subjectively improving pain experienced by our trauma patients. Based on our results, we recommend this block as an adjunct to multimodal analgesia for patients with rib fractures.

The financial burden of rib fractures: National estimates 2007 to 2016

BACKGROUND

The aim of this study is to define the cost of rib fracture hospitalization by single, multiple, and flail type using a nationally representative sample.

METHODS

The national inpatient sample (NIS) was used to identify patients with a primary diagnosis of rib fracture hospitalization 2007-2016. International Classification of Diseases, Ninth Revision (ICD-9) and Tenth Revision (ICD-10) codes were used to characterize patients as having single, multiple, or flail chest rib fractures. Patients with only trauma related diagnosis groups (DRG) at the time discharge were included in the final sample. The cost of hospitalization was obtained by converting reported charges into cost using the all-payer inpatient cost-to-charge ratio (CCR) for all hospitals in the NIS data. The log of cost was modeled using multivariate linear regression. The rib fracture type was the primary predictor in the model.

RESULTS

There were 373,053 rib fracture admissions during 2007-2016. The average cost per hospitalization was $10,169 (95%Confidence Interval [CI]: 9,942-10,395), which translated into a national expenditure of $3.64 billion over 10 years. The cost of rib fracture hospitalization increased from $209 million in 2007 to $469 million in 2016. Compared to single rib fracture patients, the cost of hospitalization for multiple rib fractures and flail chest was 3% (p = 0.001) and 5% (p=0.02) higher, respectively. Higher injury severity score, total number of body regions injured and longer length of stay were associated with higher rib fracture hospitalization cost.

CONCLUSIONS

Rib fractures affect ~22,000-45,000 people per year in the United States. The cost of rib fractures is over $469 million per year and is increasing over time. Multiple rib fractures and flail chest rib fractures are associated with increased cost. Pathways to improve care in patients with rib fractures should consider the cost of treatment.

Epidural catheters are associated with an increased risk of venous thromboembolism in trauma

Little is known about the association between epidural catheters (EC) and venous thromboembolism (VTE) in trauma. We sought to study this association and hypothesized that trauma patients with EC were more likely to develop VTE. Using the Pennsylvania Trauma Outcomes Study (PTOS) registry, we identified all adult trauma patients (age ≥ 18) admitted for at least 2 days between 1/2013 and 12/2017. Baseline characteristics and outcome variables were compared between patients who underwent EC placement and those who did not. The primary outcome was development of VTE. 147,721 patients met inclusion criteria; 2247 (1.5%) developed a VTE. Patients were mostly white (85%), male (56%), with blunt trauma (94%). 776 (0.5%) had an EC placed. Patients who underwent EC placement were more likely to develop a VTE (2.8% vs. 1.5%, p = 0.003). After adjusting for covariates, patients with EC were 1.6 times more likely to develop VTE (95% CI 1.1-2.5). The overall rate of VTE was low and associated with the use of EC. Future work should focus on determining the underlying mechanisms.

Isolated rib cage fractures in the elderly: Do all patients belong to the intensive care unit? A retrospective nationwide analysis

BACKGROUND

Western Trauma Association guidelines recommend admitting patients 65 years or older with two or more rib fractures diagnosed by chest radiograph to the intensive care unit (ICU). Increased use of computed tomography has led to identification of less severe, "occult" rib fractures. We aimed to evaluate current national trends in disposition of older patients with isolated rib cage fractures and to identify characteristics of patients initially admitted to the ward who failed ward management.

METHODS

A retrospective cohort study of patients 65 years or older with isolated two or more blunt rib cage fractures using the 2010 to 2016 American College of Surgeons Trauma Quality Improvement Program database was performed. Ward failure was defined as patients initially admitted to the ward with subsequent need for unplanned ICU admission or intubation. Multivariable analyses were derived to study the independent predictors of failure of ward management. Propensity score matching sub-analysis was used to assess outcomes in patients admitted to the ward versus ICU.

RESULTS

There were 5,021 patients included in the analysis. Of these patients, 1,406 (28.0%) were admitted to the ICU. On multivariable analysis, age was an independent predictor of ICU admission. Of the 3,577 patients admitted directly to the ward, 38 (1.1%) patients required unplanned intubation or ICU admission. Independent predictors of failure of ward management included chronic renal failure (odds ratio [OR], 7.20; p ≤ 0.001; 95% confidence interval [CI], 2.50-20.76), traumatic pneumothorax (OR, 8.70; p = 0.008; 95% CI, 1.76-42.93), concurrent sternal fracture (OR, 6.52; p ≤ 0.001; 95% CI, 2.53-16.80), drug use disorder (OR, 6.58; p = 0.032; 95% CI, 1.17-36.96), and emergency department oxygen requirement or oxygen saturation less than 95% (OR, 2.38; p = 0.018; 95% CI, 1.16-4.86). Mortality was higher in patients with delayed ICU care versus patients with successful ward disposition (21.1% vs. 0.8%; p < 0.001).

CONCLUSION

Our results suggest that the majority of isolated rib cage fractures in older patients are safely managed on the ward with exceedingly low ward failure rates (1.1%). Patients with failure of ward management have significantly higher mortality, and we have identified predictors of failing the ward.

Epidural analgesia in ICU chest trauma patients with fractured ribs: retrospective study of pain control and intubation requirements

BACKGROUND

Nonintubated chest trauma patients with fractured ribs admitted to the intensive care unit (ICU) are at risk for complications and may require invasive ventilation at some point. Effective pain control is essential. We assessed whether epidural analgesia (EA) in patients with fractured ribs who were not intubated at ICU admission decreased the need for invasive mechanical ventilation (IMV). We also looked for risk factors for IMV.

STUDY DESIGN AND METHODS

This retrospective, observational, multicenter study conducted in 40 ICUs in France included consecutive patients with three or more fractured ribs who were not intubated at admission between July 2013 and July 2015.

RESULTS

Of the 974 study patients, 788 were included in the analysis of intubation predictors. EA was used in 130 (16.5%) patients, and 65 (8.2%) patients required IMV. Factors independently associated with IMV were chronic respiratory disease (P = 0.008), worse SAPS II (P < 0.0001), flail chest (P = 0.02), worse Injury Severity Score (P = 0.0003), higher respiratory rate at admission (P = 0.02), alcohol withdrawal syndrome (P < 0.001), and noninvasive ventilation (P = 0.04). EA was not associated with decreases in IMV requirements, median numerical rating scale pain score, or intravenous morphine requirements from day 1 to day 7.

CONCLUSIONS

EA was not associated with a lower risk of IMV in chest trauma patients with at least 3 fractured ribs, moderate pain, and no intubation on admission. Further studies are needed to clarify the optimal pain control strategy in chest trauma patients admitted to the ICU, notably those with severe pain or high opioid requirements.

Comparison of intravenous lidocaine versus epidural anesthesia for traumatic rib fracture pain: a retrospective cohort study

BACKGROUND

Effective analgesia is essential in managing traumatic rib fractures. Intravenous lidocaine (IVL) is effective in treating perioperative pain, acute pain in the emergency department, cancer pain in hospice, and outpatient chronic neuropathic pain. Our study examined the associations between IVL versus epidural analgesia (EA) and pain for the treatment of acute rib fracture in the inpatient setting.

METHODS

We performed a retrospective study involving adults admitted to an academic level I trauma center from June 1, 2011 to June 1, 2016 with consults to the pain service for acute rib fracture pain. Eighty-nine patients were included in the final analysis (54 IVL and 35 EA patients). Both groups had usual access to opioid medications. The primary outcome was absolute change in numeric pain scores during 0-24 and 24-48 hours after initiating IVL or EA, compared with baseline. Secondary outcomes include opioid consumption, incentive spirometry, supplemental oxygens, pneumonia, endotracheal intubation and length of hospital stay.

RESULTS

Numeric pain scores differed at baseline (mean 5.6 for IVL vs 4.5 for EA, p=0.01), while age, injury severity, and number of fractured ribs were similar. IVL and EA were associated with similar reductions in numeric pain scores within 0-24 and 24-48 hours (mean -2.9 for IVL vs -2.3 for EA during both periods, p=0.19 and p=0.17 respectively) . There was greater non-neuraxial opioid consumption with IVL compared with EA (98.6 vs 22.3 mg morphine equivalents (MME) at 0-24 hours, p=0.0005; 105.6 vs 18.9 MME at 24-48 hours, p<0.0001). When epidural opioids were analyzed, the EA group was exposed to higher total MME at 0-24 hours (655.2 vs 98.6 MME, p<0.0001) and 24-48 hours (586 vs 105.6 MME, p=0.0001), suggesting an opioid sparing effect of IVL.

CONCLUSION

Our results suggest that IVL is similar to EA in numeric pain score reduction, and that IVL may have an opioid sparing effect when taking neuraxial opioids into account. IVL may be an effective alternative to epidurals for the treatment of rib fracture pain. It should be considered for patients who have contraindications to epidurals or are unable to receive an epidural in a timely manner.

Chest Trauma: Current Recommendations for Rib Fractures, Pneumothorax, and Other Injuries

Purpose of Review

This article provides an overview of the common and important chest injuries that the anesthesiologist may encounter in patients following trauma including blunt injury, pneumothorax, hemothorax, blunt aortic injury, and blunt cardiac injury.

Recent Findings

Rib fractures are frequently associated with chest injury and are associated with significant pain and other complications. Regional anesthesia techniques combined with a multimodal analgesic strategy can improve patient outcomes and reduce complications. There is increasing evidence for paravertebral blocks for this indication, and the myofascial plane blocks are a popular emerging technique. Recent changes to recommended management of tension pneumothorax are also described.

Summary

Chest trauma is commonly encountered, and anesthesiologists have the potential to significantly improve morbidity and mortality in this group of patients.

Epidural Analgesia for Severe Chest Trauma: An Analysis of Current Practice on the Efficacy and Safety

Background

Adequate pain control is essential in the treatment of patients with traumatic rib fractures. Although epidural analgesia is recommended in international guidelines, the use remains debatable and is not undisputed. The aim of this study was to describe the efficacy and safety of epidural analgesia in patients with multiple traumatic rib fractures.

Methods

A retrospective cohort study was performed. Patients with ≥3 rib fractures following blunt chest trauma who received epidural analgesia between January 2015 and January 2018 were included. The main outcome parameters were the success rate of epidural analgesia and the incidence of medication-related side effects and catheter-related complications.

Results

A total of 76 patients were included. Epidural analgesia was successful in a total of 45 patients (59%), including 22 patients without and in 23 patients with an additional analgesic intervention. In 14 patients (18%), epidural analgesia was terminated early without intervention due to insufficient sensory blockade (n=4), medication-related side effects (n=4), and catheter-related complications (n=6). In 17 patients (22%), the epidural catheter was removed after one or multiple additional interventions due to insufficient pain control. Minor epidural-related complications or side effects were encountered in 36 patients (47%). One patient had a major complication (opioid intoxication).

Conclusion

Epidural analgesia was successful in 59% of patients; however, 30% needed additional analgesic interventions. As about half of the patients had epidural-related complications, it remains debatable whether epidural analgesia is a sufficient treatment modality in patients with multiple rib fractures.

The expedited discharge of patients with multiple traumatic rib fractures is cost-effective

INTRODUCTION

Rib fractures are a cause of significant morbidity and mortality in trauma patients. It is well documented that optimizing pain control, mobilization, and respiratory care decreases complications. However, the impact of these interventions on hospital costs and length of stay is not well defined. We hypothesized patients with multiple rib fractures can be discharged within three hospital days resulting in decreased hospital costs.

METHODS

A retrospective review of adult patients (≥18yrs) admitted to our Level 1 trauma center (2011-2013) with ≥2 rib fractures was performed. Patients were excluded if they were intubated, admitted to the ICU, required chest tube placement, or sustained significant multi-system trauma. (n = 202) Demographics, clinical characteristics, hospital costs, and outcome data were analyzed. Patients discharged within three hospital days of admission were considered to have achieved expedited discharge (ED). Univariate and multivariate analyses determined predictors of failure to achieve ED. A p value of <0.05 was considered significant.

RESULTS

Study patients (n = 202) were 60 (SD = 19) years of age with an injury severity score (ISS) of 10 (SD = 5), and 4 (SD = 2) rib fractures. Of 202 patients, 127 (63%) achieved ED while 75 (37%) did not. No differences in chest AIS, ISS, smoking status or history of pulmonary disease were identified between the two groups (all p > 0.05). Average LOS (2 (SD = 1) vs. 7 (SD = 4) days; p < 0.001) and hospital costs ($2865 (SD = 1200) vs. $6085 (SD = 3033)); p < 0.001). were lower in the ED group A lower percentage of ED patients required placement in rehabilitation facilities (6% vs. 48%; p < 0.001). There were no readmissions within 30 days in either group. After controlling for potential confounding variables, multiple variable logistic regression analysis revealed that advancing age (OR 1.05 per year, 1.02-1.07) independently predicted failure to achieve ED.

CONCLUSION

The majority of patients admitted to the hospital with multiple rib fractures can be discharged within three days. This expedited discharge results in significant cost savings to the hospital. Early identification of patients who cannot meet the goal of expedited discharge can facilitate improvement in management strategies.

Regional Anesthesia and Analgesia for Acute Trauma Patients

Regional anesthesia for the acute trauma patient is increasing due to the growing appreciation of its benefits, development of newer techniques and equipment, and more robust training. Block procedures are expanding beyond perioperative interventions performed exclusively by anesthesiologists to paramedics on scene, emergency medicine physicians, and nurse-led services using these techniques early in trauma pain management. Special considerations and indications apply to trauma victims compared with the elective patient and must be appreciated to optimize safety and clinical outcomes. This review discusses current literature and future directions in the growing role of regional anesthesia in acute trauma care.

Development of a blunt chest injury care bundle: An integrative review

BACKGROUND

Blunt chest injuries (BCI) are associated with high rates of morbidity and mortality. There are many interventions for BCI which may be able to be combined as a care bundle for improved and more consistent outcomes.

OBJECTIVE

To review and integrate the BCI management interventions to inform the development of a BCI care bundle.

METHODS

A structured search of the literature was conducted to identify studies evaluating interventions for patients with BCI. Databases MEDLINE, CINAHL, PubMed and Scopus were searched from 1990-April 2017. A two-step data extraction process was conducted using pre-defined data fields, including research quality indicators. Each study was appraised using a quality assessment tool, scored for level of evidence, then data collated into categories. Interventions were also assessed using the APEASE criteria then integrated to develop a BCI care bundle.

RESULTS

Eighty-one articles were included in the final analysis. Interventions that improved BCI outcomes were grouped into three categories; respiratory intervention, analgesia and surgical intervention. Respiratory interventions included continuous positive airway pressure and high flow nasal oxygen. Analgesia interventions included regular multi-modal analgesia and paravertebral or epidural analgesia. Surgical fixation was supported for use in moderate to severe rib fractures/BCI. Interventions supported by evidence and that met APEASE criteria were combined into a BCI care bundle with four components: respiratory adjuncts, analgesia, complication prevention, and surgical fixation.

CONCLUSIONS

The key components of a BCI care bundle are respiratory support, analgesia, complication prevention including chest physiotherapy and surgical fixation.

Comparison of analgesic interventions for traumatic rib fractures: a systematic review and meta-analysis

Purpose

Many studies report on outcomes of analgesic therapy for (suspected) traumatic rib fractures. However, the literature is inconclusive and diverse regarding the management of pain and its effect on pain relief and associated complications. This systematic review and meta-analysis summarizes and compares reduction of pain for the different treatment modalities and as secondary outcome mortality during hospitalization, length of mechanical ventilation, length of hospital stay, length of intensive care unit stay (ICU) and complications such as respiratory, cardiovascular, and/or analgesia-related complications, for four different types of analgesic therapy: epidural analgesia, intravenous analgesia, paravertebral blocks and intercostal blocks.

Methods

PubMed, EMBASE and CENTRAL databases were searched to identify comparative studies investigating epidural, intravenous, paravertebral and intercostal interventions for traumatic rib fractures, without restriction for study type. The search strategy included keywords and MeSH or Emtree terms relating blunt chest trauma (including rib fractures), analgesic interventions, pain management and complications.

Results

A total of 19 papers met our inclusion criteria and were finally included in this systematic review. Significant differences were found in favor of epidural analgesia for the reduction of pain. No significant differences were observed between epidural analgesia, intravenous analgesia, paravertebral blocks and intercostal blocks, for the secondary outcomes.

Conclusions

Results of this study show that epidural analgesia provides better pain relief than the other modalities. No differences were observed for secondary endpoints like length of ICU stay, length of mechanical ventilation or pulmonary complications. However, the quality of the available evidence is low, and therefore, preclude strong recommendations.

Pain management for blunt thoracic trauma: A joint practice management guideline from the Eastern Association for the Surgery of Trauma and Trauma Anesthesiology Society

INTRODUCTION

Thoracic trauma is the second most prevalent nonintentional injury in the United States and is associated with significant morbidity. Analgesia for blunt thoracic trauma was first addressed by the Eastern Association for the Surgery of Trauma (EAST) with a practice management guideline published in 2005. Since that time, it was hypothesized that there have been advances in the analgesic management for blunt thoracic trauma. As a result, updated guidelines for this topic using the GRADE (Grading of Recommendations, Assessment, Development, and Evaluation) framework recently adopted by EAST are presented.

METHODS

Five systematic reviews were conducted using multiple databases. The search retrieved articles regarding analgesia for blunt thoracic trauma from January1967 to August 2015. Critical outcomes of interest were analgesia, postoperative pulmonary complications, changes in pulmonary function tests, need for endotracheal intubation, and mortality. Important outcomes of interest examined included hospital and intensive care unit length of stay.

RESULTS

Seventy articles were identified. Of these, 28 articles were selected to construct the guidelines. The overall risk of bias for all studies was high. The majority of included studies examined epidural analgesia. Epidural analgesia was associated with lower short-term pain scores in most studies, but the quality and quantity of evidence were very low, and no firm evidence of benefit or harm was found when this modality was compared with other analgesic interventions. The quality of evidence for paravertebral block, intrapleural analgesia, multimodal analgesia, and intercostal nerve blocks was very low as assessed by GRADE. The limitations with the available literature precluded the formulation of strong recommendations by our panel.

CONCLUSION

We propose two evidence-based recommendations regarding analgesia for patients with blunt thoracic trauma. The overall risk of bias for all studies was high. The limitations with the available literature precluded the formulation of strong recommendations by our panel. We conditionally recommend epidural analgesia and multimodal analgesia as options for patients with blunt thoracic trauma, but the overall quality of evidence supporting these modalities is low in trauma patients. These recommendations are based on very low-quality evidence but place a high value on patient preferences for analgesia. These recommendations are in contradistinction to the previously published Practice Management Guideline published by EAST.

Chest Wall Trauma

Chest wall trauma is common, and contributes significantly to morbidity and mortality of trauma patients. Early identification of major chest wall and concomitant intrathoracic injuries is critical. Generalized management of multiple rib fractures and flail chest consists of adequate pain control (including locoregional modalities); management of pulmonary dysfunction by invasive and noninvasive means; and, in some cases, surgical fixation. Multiple studies have shown that patients with flail chest have substantial benefit (decreased ventilator and intensive care unit days, improved pulmonary function, and improved long-term functional outcome) when they undergo surgery compared with nonoperative management.
