General anesthesia vs spinal anesthesia for patients undergoing total-hip arthroplasty: A meta-analysis

Utility of spinal anesthesia in plastic surgery and other surgical subspecialties: A literature review

INTRODUCTION

Spinal anesthesia (SA) is commonly used within the specialties of orthopedic surgery, obstetrics and gynecology, spine surgery, and general surgery, and offers several benefits over general anesthesia (GA). However, SA is used much less frequently in plastic surgery. This review analyzed currently existing data on SA use across various surgical specialties and compared the benefits and complications of SA to those of GA, to assess its utility and potential for more widespread use in plastic surgery.

METHODS

A comprehensive literature review was conducted using the PubMed and Cochrane Library databases to evaluate the utility of SA in plastic surgery. Indications, contraindications, and data on the use of SA across various surgical specialties were reviewed. Benefits, complications, and cost-effectiveness were also assessed. Finally, the utility of SA in plastic surgery was evaluated based on the available literature.

RESULTS

SA has been shown to yield several benefits and fewer risks than GA, including a higher possibility of early discharge, decreased costs, better pain and postoperative nausea and vomiting control, and decreased risk of deep venous thrombosis and pulmonary embolism.

CONCLUSION

Although commonly used for procedures across various surgical specialties such as obstetrics and gynecology, urology, and orthopedic surgery, SA is less frequently used within plastic surgery. Plastic surgery procedures that would benefit from the use of SA include those below the umbilicus such as liposuction, lower extremity procedures, and perineal procedures, and owing to its benefits, we recommend that SA be used more often within plastic surgery under appropriate clinical circumstances.

Morbidity and Mortality Following Total Hip and Knee Arthroplasty With Spinal Versus General Anesthesia: A Retrospective Analysis

BACKGROUND

The optimal anesthetic mode in total joint arthroplasty (TJA) has yet to be clearly identified. Patients undergoing TJA may recieve spinal anesthesia (SA) or general anesthesia (GA). While arthroplasty literature indicates differences in postoperative morbidity, hip fracture literature does not show clear superiority of SA or GA. The purpose of this study was to further investigate this relationship and determine if there is a significant difference in morbidity and mortality between GA and SA in patients undergoing primary total joint arthroplasty.

METHODS

Patients undergoing primary THA or TKA from February 2007 to February 2021 were retrospectively reviewed, creating four cohorts: THA/GA (n = 1,266), THA/SA (n = 1,084), TKA/GA (n = 882), and THA/SA (n = 2,067). Readmission within 90 days, mortality within 365 days, and thromboembolic events within 30 days postoperatively were compared using logistic regression, controlling for age, body mass index, and Charlson Comorbidity Index.

RESULTS

The odds of experiencing a deep venous thrombosis within 30 days postoperatively were elevated in the analysis of both the THA/GA (odds ratio (OR) = 3.1; 95% confidence interval (CI): 1.5 to 7.0; P = .004) and the TKA/GA (OR = 1.9; 95% CI: 1.2 to 3.0; P = .005) groups. Similarly, the risk of pulmonary embolism as higher in the THA/GA cohort (OR = 3.9; 95% CI: 1.2 to 17.3; P = .04). There were also higher odds of mortality within 365 days postoperatively in THA/GA patients (OR = 4.3; 95% CI: 1.7 to 13.0; P = .004). No other differences existed among TKA patients.

CONCLUSIONS

Based upon these data, both SA and GA are reasonable options for primary TKA with similar risk profiles. However, GA may be associated with higher rates of deep venous thrombosis in TJA and pulmonary embolism in THA. General anesthesia (GA) was also loosely associated with increased mortality within 1 year of THA, but this result should be considered with caution.

Successful Ultrasound-Guided Spinal Anesthesia in a Patient With Severe Hemophilia A Undergoing Total Hip Arthroplasty

Neuraxial anesthesia is the preferred technique for total joint arthroplasties. However, the absolute safety of neuraxial anesthesia in hemophilia patients has not been established. We describe a case of an adult male with severe hemophilia A, who presented for primary hip replacement due to severe hemophilic arthropathy and was managed with ultrasound-facilitated neuraxial anesthesia. Due to bleeding risks, additional considerations were necessary to minimize development of postoperative spinal hematoma. There were no perioperative adverse events. Careful preoperative multidisciplinary planning, perioperative management of neuraxial anesthesia (including the use of spinal ultrasound), and hemostasis were instrumental to successfully accomplish this. Following these principles, we demonstrate that neuraxial techniques may be a safe option for managing patients with severe hemophilia A.

A Retrospective Analysis Investigating Whether Case Volume Experience of the Anesthesiologist Correlates with Intraoperative Efficiency for Joint Arthroplasty

The objective of this retrospective study was to determine if there was an association between anesthesiology experience (e.g. historic case volume) and operating room (OR) efficiency times for lower extremity joint arthroplasty cases. The primary outcome was time from patient in the OR to anesthesia ready (i.e. after spinal or general anesthesia induction was complete). The secondary outcomes included time from anesthesia ready to surgical incision, and time from incision to closing completed. Mixed effects linear regression was performed, in which the random effect was the anesthesiology attending provider. There were 4,575 patients undergoing hip or knee arthroplasty included. There were 82 unique anesthesiology providers, in which the median [quartile] frequency of cases performed was 79 [45, 165]. On multivariable mixed effects linear regression - in which the primary independent variable (anesthesiologist case volume history for joint arthroplasty anesthesia) was log-transformed - the estimate for log-transformed case volume was - 0.91 (95% confidence interval [CI] -1.62, -0.20, P = 0.01). When modeling time from incision to closure complete, the estimate for log-transformed case volume was - 2.07 (95% -3.54, -0.06, P = 0.01). Thus, when comparing anesthesiologists with median case volume (79 cases) versus those with the lowest case volume (10 cases), the predicted difference in times added up to only approximately 6 min. If the purpose of faster anesthesia workflows was to open up more OR time to increase surgical volume in a given day, this study does not support the supposition that anesthesiologists with higher joint arthroplasty case volume would improve throughput.

Clinical Characteristics of Spinal versus General Anaesthesia in Older Patients Undergoing Hip Fracture Repair Surgery in Jordan: A Multicentre Study

BACKGROUND

The primary aim of this study was to examine the clinical characteristics and outcomes of older patients who underwent hip fracture repair surgery. The secondary aims were to assess the predictors of the choice of spinal or general anaesthesia and to explore the risk factors for all-cause mortality.

METHODS

This three-tertiary centres study was conducted at a tertiary care centre in Jordan. Clinical data include previous fracture history; medication details; comorbidities; surgical approach; and postoperative pain management.

RESULTS

Overall, 1084 patients who underwent hip fracture repair were included in this study. The mean age of patients was 78 years, and 55.2% were women. Twenty-four were treated with bisphosphonates before the fracture, whereas 30 were in steroid therapy. Overall, 61.8% of patients underwent spinal anaesthesia, whereas 38.2% underwent general anaesthesia. Spinal anaesthesia group had a lower prevalence of cardiovascular accidents (16.3% vs. 22.3%, p = 0.014) and Alzheimer's (3.4% vs. 1.4%, p = 0.049) than the general anaesthesia group. In the spinal anaesthesia group, postoperative opioid administration (p = 0.025) and postoperative blood transfusion (p = 0.011) occurred more frequently than general anaesthesia group. In hospital, 30-day and all-cause mortality were comparable between both groups. Diabetes mellitus (HR = 2.6; 95%CI = 1.5-4.4; p = 0.001); cemented hip hemiarthroplasty (HR = 2.4; 95%CI = 1.1-5.1; p = 0.025); deep venous thrombosis/pulmonary embolism (HR = 5.0; 95%CI = 1.2-12.9; p = 0.001); and readmission within 1 month from surgery (HR = 3.6; 95%CI = 2.0-6.3; p < 0.001) were all significant predictors of mortality.

CONCLUSIONS

This study provides insights into the outcomes and factors associated with different anaesthesia types in hip fracture repair surgery. The anaesthesia type does not affect all-cause mortality in patients undergoing hip fracture repair.

Prolongation of spinal duration by escalating doses of intrathecal epinephrine in lower limb arthroplasty

Aim: The optimal dose of low-dose intrathecal epinephrine in the absence of intrathecal opioids is unknown. Materials & methods: Prospective, randomized, double blind clinical trial of patients undergoing lower limb arthroplasties. The primary end point was spinal block duration measured via motor and sensory block duration. Results: 30 patients undergoing lower limb arthroplasty were randomized into one of six groups with varying intrathecal epinephrine doses 0-100 mcg. There was a direct linear effect between motor block duration and intrathecal epinephrine dose with higher doses being associated with longer block duration (p = 0.011). Mean motor block duration was 3.74 ± 1.13, 3.36 ± 0.47, 3.39 ± 0.60, 4.06 ± 0.98 and 5.20 ± 1.41 h for the EPI0, EPI25, EPI50, EPI75 and EPI100 groups respectively. Conclusion: This study reveals that low-dose intrathecal epinephrine (75-100 mcg) in the absence of intrathecal opioids can be reliably used to prolong motor block duration in lower limb arthroplasty. Clinical Trial Registration: NCT02619409 (ClinicalTrials.gov).

Enhanced recovery after surgery (ERAS) protocols for total joint replacement surgery

The enhanced recovery after surgery (ERAS) protocols are a comprehensive therapeutic approach that prioritizes the well-being of patients. It encompasses several aspects such as providing sufficient nutritional support, effectively managing pain, ensuring appropriate fluid management and hydration, and promoting early mobilization after surgery. The advent of ERAS theory has led to a shift in focus within modern ERAS protocols. At present, ERAS protocols emphasize perioperative therapeutic strategies employed by surgeons and anesthesiologists, as well as place increased importance on preoperative patient education, interdisciplinary collaboration, and the enhancement of patient satisfaction and clinical outcomes. This editorial highlights the application of ERAS protocols in the current context of total joint replacement surgery.

Body Mass Index (BMI) Related Morbidity with Thyroid Surgery

OBJECTIVES

The increase in incidence of thyroid cancer correlates with strict increases in body mass index (BMI) and obesity in the United States. Thyroid hormone dysregulation has been shown to precipitate circulatory volume, peripheral resistance, cardiac rhythm, and even cardiac muscle health. Theoretically, thyroid surgery could precipitate injury to the cardiopulmonary system.

METHODS

The American College of Surgery National Quality Improvement Program database was queried for thyroidectomy cases in the 2007-2020 Participant User files. Continuous and categorical associations between BMI and cardiopulmonary complications were investigated as reported in the database.

RESULTS

The query resulted 186,095 cases of thyroidectomy procedures in which the mean age was 51.3 years and sample was 79.3% female. No correlation was evident in univariate and multivariate analyses between BMI and the incidence of postoperative stroke or myocardial infarction. The incidence of complications was extremely low. However, risk of deep venous thrombosis correlated with BMI in the categorical, univariate, and multivariate (OR 1.036, CI 1.014-1.057, p < 0.01) regression analysis. Additionally, increased BMI was associated with increased risk of pulmonary embolism (PE) (OR 1.050 (1.030, 1.069), p < 0.01), re-intubation (OR 1.012 (1.002, 1.023), p = 0.02), and prolonged intubation (OR 1.031 (1.017, 1.045), p < 0.01).

CONCLUSION

Despite the rarity of cardiopulmonary complications during thyroid surgery, patients with very high BMI carry a significant risk of deep venous thrombosis, PE, and prolonged intubation.

Fast Track Protocols and Early Rehabilitation after Surgery in Total Hip Arthroplasty: A Narrative Review

The Enhanced Recovery After Surgery (ERAS) or Fast Track is defined as a multi-disciplinary, peri- and post-operative approach finalized to reduce surgical stress and simplify post-operative recovery. It has been introduced more than 20 years ago by Khelet to improve outcomes in general surgery. Fast Track is adapted to the patient's condition and improves traditional rehabilitation methods using evidence-based practices. Fast Track programs have been introduced into total hip arthroplasty (THA) surgery, with a reduction in post-operative length of stay, shorter convalescence, and rapid functional recovery without increased morbidity and mortality. We have divided Fast Track into three cores: pre-, intra-, and post-operative. For the first, we analyzed the standards of patient selection, for the second the anesthesiologic and intraoperative protocols, for the third the possible complications and the appropriate postoperative management. This narrative review aims to present the current status of THA Fast Track surgery research, implementation, and perspectives for further improvements. By implementing the ERAS protocol in the THA setting, an increase in patient satisfaction can be obtained while retaining safety and improving clinical outcomes.

Study protocol for discharge on day of surgery after hip and knee arthroplasty from the Center for Fast-track Hip and Knee Replacement

BACKGROUND AND PURPOSE

Limited data exists on the implementation process and safety of discharge on the day of surgery after primary hip and knee arthroplasty in a multicenter setting. We report our study protocol on the investigation of the feasibility, safety, and socioeconomic aspects following discharge on day of surgery after hip and knee arthroplasty across 8 fast-track centers.

PATIENTS AND METHODS

This is a study protocol for a prospective cohort study on discharge on day of surgery from the Center for Fast-track Hip and Knee Replacement. The collaboration includes 8 centers covering 40% of the primary hip and knee arthroplasty procedures undertaken in Denmark. All patients scheduled for surgery are screened for eligibility using well-defined inclusion and exclusion criteria. Eligible patients fulfilling discharge criteria will be discharged on day of surgery. We expect to screen 9,000 patients annually. Duration and outcome: Patients will be enrolled over a 3-year period from September 2022 and reporting of results will run continuously until December 2025. We shall report the proportion of eligible patients and patients discharged on day of surgery as well as limiting factors. Readmissions and complications within 30 days are recorded with real-time follow-up by research staff. Furthermore, patient-reported information on willingness to repeat discharge on day of surgery, contacts with the healthcare system, complications, and workability is registered 30 days postoperatively. EQ-5D, Oxford Knee Score, and Oxford Hip Score are completed preoperatively and after 3 months and 1 year. Finally, outcome data will be used in the development of a prediction model for successful discharge on the day of surgery.

Key Elements of Enhanced Recovery after Total Joint Arthroplasty: A Reanalysis of the Enhanced Recovery after Surgery Guidelines

Recent guidelines have produced a consensus statement for perioperative care in hip and knee replacement. However, there is still a need for reanalysis of the evidence and recommendations. Therefore, we retrieved and reanalyzed the evidence of each recommended components of enhanced recovery after surgery (ERAS) based on the guidelines of total joint arthroplasty. For each one, we included for the highest levels of evidence and those systematic reviews and meta-analyses were preferred. The full texts were analyzed and the evidence of all components were summarized. We found that most of the recommended components of ERAS are supported by evidence, however, the implementation details of each recommended components need to be further optimized. Therefore, implementation of a full ERAS program may maximize the benefits of our clinical practice but this combined effect still needs to be further determined.

Spinal anesthesia does not cause left ventricular dysfunction in patients older than 60 years without cardiovascular disease

BACKGROUND

Elderly patients are undergoing surgery more frequently than ever. In this population, spinal anesthesia, which is known to cause sympathetic blockade associated with arterial vasodilation, is proposed as an excellent option. However, its effects on left ventricular systolic function have not been studied.

OBJECTIVES

To evaluate left ventricular systolic function by transthoracic echocardiography in patients older than 60 years, without prior cardiovascular disease, under spinal anesthesia.

PATIENTS AND METHODS

Prospective observational study with a total of 54 patients older than 60 years without prior cardiovascular disease, in whom, after the completion of subarachnoid anesthesia with hyperbaric 0.5% bupivacaine with sensory block equal to or greater than T10, left ventricular systolic function was measured using MAPSE. In addition, CI-IVC, LVOT-VTI and CO were measured. Values at 5 min after the blockade were compared with those obtained previously.

RESULTS

A 3.3% decrease in MAPSE and a slight decrease in LVOT-VTI and CO were found, with no statistical or clinical significance. 14.8% of the patients presented MAP equal to or less than 60 mmHg. Comparison of echocardiographic changes between hypotensive and non-hypotensive patients was not statistically significant or clinically relevant.

DISCUSSION

Our study shows that spinal anesthesia with anesthetic level T10 or higher in patients older than 60 years without cardiovascular disease is a safe technique since it does not significantly alter echocardiographic parameters measuring left ventricular systolic function.

Operative room time comparison between general and spinal anesthesia in total hip arthroplasty: an institutional study

PURPOSE

A relatively high expense with any procedure is total operative time; two components being the time spent anesthetizing the patient and time spent transferring the patient out of the operating room (OR). Both times can be affected by the anesthetic method used. This study compares different operative time intervals for both spinal anesthesia (SA) and general anesthesia (GA), in patients undergoing a primary total hip arthroplasty (THA), to identify the most appropriate and cost-effective anesthetic method.

METHODS

A retrospective chart review was performed at a single institution for primary total hip arthroplasty procedures performed in the year 2019. Primary THAs without complications performed by three orthopedic surgeons were selected. Anesthesia records for 200 patients were used to compare perioperative time intervals; 100 consecutive patients that received SA and 100 consecutive patients that received GA.

RESULTS

The time spent transferring the patient out of the operating room was 8 min for GA and 5 min for SA (p < 0.001). Total operative time for GA was 90 min and 87 min for SA (p = 0.3330). Total pre-operative time averaged 26 min in SA compared to 25 min in GA (p = 0.5874). Non-operative total time (all time components of patient interaction excluding surgery start to surgery finish) was significantly shorter in SA with an average of 52 compared to 56 in GA (p = 0.0151).

CONCLUSION

Time to transfer patient out of the OR and total non-operative time was significantly shorter in patients who received spinal anesthesia. These results and the complications of both general and spinal anesthesia should be taken into consideration when anesthetizing patients undergoing primary THA.

Patient on Multiple Hormone Replacement Therapy for Hip Arthroplasty: How to Omit Noise and Be Focused?

Total hip arthroplasty (THA) surgery is usually performed in patients with trauma or old-aged osteoarthritis. There has been a recent increase in younger patients presenting with avascular necrosis (AVN) of the hip requiring replacement arthroplasty. Despite being from a younger age group, these patients may present with multiple comorbidities. We describe one such case of Cushing’s syndrome with AVN in a young patient with primary adrenal insufficiency, secondary hypothyroidism, and secondary hypogonadism on replacement therapy status post-transsphenoidal pituitary surgery and bilateral adrenalectomy, currently posted for total hip replacement (THR) surgery.

Routine Indwelling Urinary Catheterization Is Not Necessary During Total Hip Arthroplasty Performed Under Spinal Anesthesia

Background

Perioperative indwelling urinary catheterization remains common in patients undergoing total hip arthroplasty. This study sought to examine the effect of routine catheterization following total hip arthroplasty performed under spinal anesthesia on urinary complications.

Methods

A total of 991 consecutive patients who underwent primary total hip arthroplasty under spinal anesthesia over a 4-year period were retrospectively reviewed. Major postoperative urinary retention (POUR) was defined as persistent retention following 2 straight catheterizations, which required postoperative indwelling catheter placement. Minor POUR was defined as retention that resolved following 1 or 2 straight catheterizations. Statistical analyses were used to compare outcomes between those who received a routine indwelling catheter and those who did not.

Results

Of the 991 patients included, 498 (50.3%) underwent routine indwelling urinary catheter placement preoperatively. Routine indwelling catheterization was associated with a higher rate of urinary tract infection (1.4% vs 0.0%, P = .015), but a lower rate of minor POUR (5.0% vs 10.3%, P = .001). There was no difference with respect to the rate of major POUR or discharge with an indwelling catheter. Multivariate analyses demonstrated indwelling catheterization to be independently associated with a lower rate of minor POUR (P = .021), but there was no association with overall POUR, major POUR, or discharge with a urinary catheter.

Conclusion

These data suggest that routine indwelling urinary catheterization is likely unnecessary for patients undergoing total hip arthroplasty in the setting of spinal anesthetic and may even lead to increased risk of complications such as urinary tract infection.

Observation of Anesthetic Effect of Dexmedetomidine Combined With Intraspinal Anesthesia in Hip Arthroplasty and its Effect on Postoperative Delirium and Stress Response

Objective

To observe the anesthetic effect of dexmedetomidine combined with spinal anesthesia in hip arthroplasty, and to analyze the effects of dexmedetomidine on postoperative stress response, incidence of delirium, immune function and inflammatory indicators.

Methods

A total of 42 patients who underwent hip replacement in our hospital from March 2020 to June 2021 were selected as the research subjects and randomly divided into the control group and the observation group, 21 cases in each group. The control group was given intraspinal anesthesia, and the observation group was given dexmedetomidine on this basis. The onset time and maintenance time of sensory and motor nerve block were recorded. Stress response indexes [cortisol (Cor), blood glucose (Glu), adrenaline (E), noadrenaline (NE)], T lymphocyte subsets (CD3+, CD4+, CD8+, CD4+/CD8+), inflammatory indexes [tumor necrosis factor -α (TNF-α) and interleukin-6 (IL-6)] were detected before and after operation, and the incidence of postoperative delirium in both groups was recorded.

Results

The onset time of sensory nerve block and motor block in the observation group were lower than those in the control group, and the retention time of sensory nerve block and motor nerve block were higher than those in the control group (P < 0.05). After surgery, the levels of Cor, Glu, E and NE in the observation group were lower than those in the control group (P < 0.05). After surgery, the incidence of postoperative delirium in the observation group (4.79%) was lower than that in the control group (28.57%) (P < 0.05). After surgery, the levels of CD3+, CD4+, CD8+, and CD4+/CD8+ in the observation group were higher than those in the control group (P < 0.05). After surgery, the levels of TNF-α and IL-6 in the observation group were lower than those in the control group (P < 0.05).

Conclusion

The combined use of dexmedetomidine and intraspinal anesthesia has good anesthesia effect in hip joint replacement, which can greatly reduce the stress response of patients, reduce the incidence of postoperative delirium, and effectively restore the immune function of patients, reduce the level of inflammatory response, and has high clinical application value.

Optimizing Rapid Recovery After Anterior Hip Arthroplasty Surgery: A Comparative Study of Fascia Iliaca Compartment Block and Local Infiltration Analgesia

BACKGROUND

Multimodal pain therapy combining analgesics, local infiltration analgesia (LIA) and peripheral nerve blocks, such as fascia iliaca compartment block (FICB), can improve postoperative pain, nausea and vomiting (PONV) and ambulation in patients undergoing total hip arthroplasty (THA). We hypothesized that addition of FICB would decrease opioid requirements and length of stay (LOS) but could create a motor block.

METHODS

This is a single center, prospective, blinded randomized controlled study of 152 patients undergoing elective THA via direct anterior approach from October 2019 till August 2021. Three patient groups were defined: patients receiving only spinal anesthesia (control group, n = 53); spinal anesthesia with LIA perioperatively (n = 50); and spinal anesthesia with FICB on the recovery unit (n = 49). Outcome measures consisted of postoperative pain scores, PONV, length of hospital stay, opioid requirements and mobility.

RESULTS

Overall pain scores were low for all patient groups, with a lower pain score for LIA in comparison to the control group until 4 hours postoperatively (P < .05). Length of hospital stay, postoperative pain, nausea and vomiting (PONV) scores and quadriceps muscle strength did not differ significantly between groups. The control group showed higher scores at 12 hours postoperatively in comparison to FICB regarding rehabilitation potential, use of walking aids and activities of daily living (P < .05), but all groups reached the same endpoint 48 hours postoperatively. The LIA and FICB groups required less opioids until 24 hours postoperatively.

CONCLUSION

LIA is a beneficial adjuvant therapy to spinal anesthesia in THA patients as it may decrease pain scores and the need for opioid consumption. Adjuvant FICB only provided lower opioid requirements.

Anesthetic Effect of the Fascia Iliaca Compartment Block with Different Approaches on Total Hip Arthroplasty and Its Effect on Postoperative Cognitive Dysfunction and Inflammation

Objective

The objective of this article is to make a comparison of the anesthetic effects of the inside and outside fascia iliaca compartment block (FICB) in total hip arthroplasty (THA) and to study the effect of the different approaches of the FICB on postoperative cognitive dysfunction (POCD) and serum inflammatory cytokines in THA patients.

Methods

A total of 60 patients who received THA treatment from January 2021 to December 2021 were divided into two groups, namely, Inside group (inside approach of the FICB) and Outside group (outside approach of the FICB), according to the different approaches of the FICB. Forty-eight hours after surgery, we compared the use of ropacaine dosage, visual analogue scale (VAS) score, the use of patient-controlled analgesia (PCA), mini-mental state examination (MMSE) score, the incidence of POCD, and the serum levels of IL-1, IL-6. Secondary indicators include surgical indicators and the quality of anesthesia cannula.

Results

The ratio of re-fix the catheter, intubation time, and the use of ropacaine dosage at 48 h after surgery in the Outside group were significantly higher than that in the Inside group (p &lt; 0.05), while the depth of cannulation in the Outside group was significantly lower than that in the Inside group (p &lt; 0.05). VAS scores were comparable between the Inside and the Outside groups, except at 24 h after surgery. The use of PCA from 24 to 48 h after surgery in the Outside group was significantly higher than that in the Inside group (p &lt; 0.05). The MMSE score and the incidence of POCD in the Outside group were higher than that in the Inside group. At the same time, the serum IL-1β levels at 1 and 6 h after surgery and the serum IL-6 levels at 1, 6, 24, and 48 h after surgery in the Outside group were significantly higher than that in the Inside group (p &lt; 0.05).

Conclusion

Compared with the outside approach of the FICB, the inside approach of the FICB has better anesthetic effect, better postoperative analgesia, fewer postoperative analgesics, lower incidence of POCD, and lower serum cytokines during the treatment of THA patients.

Spinal anesthesia versus combined sciatic nerve/lumbar plexus nerve block in elderly patients undergoing total hip arthroplasty: a retrospective study

BACKGROUND

The most important cause of mortality due to long bone fractures in the elderly patients are femoral fractures that require total hip arthroplasty (THA). THA surgeries may cause severe postoperative pain, long hospital stays, a need for transfusion and mortality.

OBJECTIVE

Compare outcomes of spinal anesthesia (SA) versus combined sciatic nerve/lumbar plexus block (CSLPB).

DESIGN

Retrospective cohort trıal.

SETTING

University hospital in Turkey.

PATIENTS AND METHODS

We selected patients from the electronic medical records by date of surgery (most recent first) and compared demographic and pre- and postoperative clinical characteristics including the amount of opioid use within the first 48 postoperative hours, 30-day mortality rates, length of hospital stay, intraoperative oxygen saturation (SpO₂) and mean arterial pressure (MAP) values, duration of the surgery, and blood transfusion need.

MAIN OUTCOME MEASURE

Opioid use within the first 48 postoperative hours.

SAMPLE SIZE

204, 102 patients in each group with overall median (IQR) age of 82 (10.2) years.

RESULTS

There was no significant difference between the groups in terms of the amount of opioid use within the postoperative 48 hours, 30-day mortality rates, intensive care need, duration of the surgery, blood transfusion need, and length of hospital stay. While the intraoperative SpO₂ value was lower in the CSLPB group (P=.03), MAP values were lower in the SA group (P=.046). Preoperative American Society of Anesthesiology score (ASA) scores (P=.039) and the number of comorbidities were higher in the CSLPB group.

CONCLUSION

We prefer CSLPB used with standardized sedation protocols for anesthesia in THA surgery in elderly patients.

LIMITATIONS

Retrospective design and single-centered.

CONFLICT OF INTEREST

None.

Application effects of remimazolam and propofol on elderly patients undergoing hip replacement

Objective

To explore the anesthetic and analgesic effects of remimazolam and propofol in elderly patients undergoing hip replacement and their effects on respiratory and circulatory systems, stress and cognitive function.

Methods

Sixty elderly patients undergoing elective hip replacement in the hospital were selected as the research subjects, and they were divided into the remimazolam group and the propofol group according to the admission sequence of patients. The remimazolam group was anesthetized with remimazolam, and the propofol group was anesthetized with propofol. The anesthesia-related indicators, perioperative pain degree [Visual Analogue Scale (VAS)], circulatory indicators [heart rate, mean arterial pressure (MAP)] before anesthesia (T₀), immediately before laryngeal mask insertion (T₁), at 5 min after laryngeal mask insertion (T₂), at 30 min after laryngeal mask insertion (T₃) and at 5 min after laryngeal mask removal (T₄), stress response indicators (plasma epinephrine, norepinephrine, cortisol) before anesthesia induction and at 24 h and 72 h after surgery, cognitive function [Mini-Mental State Examination (MMSE)] and adverse reactions were compared between the two groups.

Results

Among the 60 enrolled patients, only 1 case was excluded due to withdrawal, thus 30 cases in the remimazolam group and 29 cases in the propofol group were included. There were statistically significant differences in the heart rate, MAP, plasma epinephrine, norepinephrine, cortisol and VAS score in the two groups from the aspects of interaction effect and time-point effect (P < 0.05). The heart rate and MAP at T₁, T₂ and T₃ in the two groups were significantly decreased compared with those at T₀, but the heart rate and MAP in the remimazolam group at T₁, T₂ and T₃ were significantly higher than those in the propofol group (P < 0.05). There were no statistical differences in the anesthesia time, awakening time and extubation time between the remimazolam group and the propofol group (P > 0.05). The levels of plasma epinephrine, norepinephrine and cortisol in the two groups were significantly higher at 24 h and 72 h after surgery than those before anesthesia induction, and the above levels were significantly lower in the remimazolam group than those in the propofol group (P < 0.05). The VAS scores at each time point in the two groups were significantly reduced compared to before surgery, but there was no statistically significant difference between the two groups after surgery (P > 0.05). The MMSE scores of the two groups were significantly lower at 1 d and 3 d after surgery compared with those before anesthesia induction, but the score in the remimazolam group was significantly higher than that in the propofol group (P < 0.05). In addition, the incidence rates of adverse reactions were significantly lower in the remimazolam group compared to the propofol group (P < 0.05).

Conclusion

Compared with propofol, remimazolam can achieve equivalent anesthetic and analgesic effects in elderly patients undergoing hip replacement. However, the latter one can significantly relieve respiratory and circulatory suppression, stress response and cognitive dysfunction, with good safety.

The Risk of Bleeding and Adverse Events with Clopidogrel in Elective Hip and Knee Arthroplasty Patients

Orthopedic surgeons often face a clinical dilemma on how to manage antiplatelet therapies during the time of surgery. This retrospective study is aimed to investigate the bleeding risk and adverse events in patients who hold or keep clopidogrel during elective major joints arthroplasty. Two hundred and ninety-six patients that were treated with clopidogrel while undergoing total hip or knee joint replacement between January 2009 and December 2018 were studied. Group 1 included 56 patients (18.9%) who kept using clopidogrel preoperatively. Group 2 included 240 patients who hold clopidogrel use ≥5 days preoperatively. Blood transfusion rates, estimated blood loss, complication rates, and adverse cardiocerebral events were collected and analyzed. The mean total blood loss was more in the group 1 patients as compared with that in the group 2 patients (1212.3 mL (685.8 to 2811.8) vs. 1068.9 mL (495.6 to 3294.3), p = 0.03). However, there was no significant difference between the two groups of patients regarding transfusion rates, bleeding-related complications, and infection rates. There was a trend toward a higher incidence of adverse cardiocerebral events in patients withholding clopidogrel for more than 5 days before surgery. The results of this study suggest that clopidogrel continuation could be safe and advisable for patients at thrombotic risk undergoing primary major joint replacement. Acute antiplatelet withdrawal for an extended period of time might be associated with an increased risk of postoperative thromboembolic events. More studies are required in the future to further prove this suggestion.

Outcomes of an Institutional Rapid Recovery Protocol for Total Joint Arthroplasty at a Safety Net Hospital

Rapid recovery protocols (RRPs) for total joint arthroplasty (TJA) can reduce hospital length of stay (LOS) and improve patient care in select cohorts; however, there is limited literature regarding their utility in marginalized patient populations. This report aimed to evaluate the outcomes of an institutional RRP for TJA at a safety net hospital.

Enhanced recovery after surgery for major orthopedic surgery: a narrative review

Background

With increasing interest in enhanced recovery after surgery (ERAS), the literature on ERAS in orthopedic surgery is also rapidly accumulating. This review article aims to (1) summarize the components of the ERAS protocol applied to orthopedic surgery, (2) evaluate the outcomes of ERAS in orthopedic surgery, and (3) suggest practical strategies to implement the ERAS protocol successfully.

Main body

Overall, 17 components constituting the highly recommended ERAS protocol in orthopedic surgery were identified. In the preadmission period, preadmission counseling and the optimization of medical conditions were identified. In the preoperative period, avoidance of prolonged fasting, multimodal analgesia, and prevention of postoperative nausea and vomiting were identified. During the intraoperative period, anesthetic protocols, prevention of hypothermia, and fluid management, urinary catheterization, antimicrobial prophylaxis, blood conservation, local infiltration analgesia and local nerve block, and surgical factors were identified. In the postoperative period, early oral nutrition, thromboembolism prophylaxis, early mobilization, and discharge planning were identified. ERAS in orthopedic surgery reduced postoperative complications, hospital stay, and cost, and improved the patient outcomes and satisfaction with accelerated recovery. For successful implementation of the ERAS protocol, various strategies including the standardization of care system, multidisciplinary communication and collaboration, ERAS education, and continuous audit system are necessary.

Conclusion

The ERAS pathway enhanced patient recovery with a shortened length of stay, reduced postoperative complications, and improved patient outcomes and satisfaction. However, despite the significant progress in ERAS implementation in recent years, it has mainly focused on major surgeries such as arthroplasty. Therefore, further efforts to apply, audit, and optimize ERAS in various orthopedic surgeries are necessary.

Simple and Efficient Pressure Ulcer Reconstruction via Primary Closure Combined with Closed-Incision Negative Pressure Wound Therapy (CiNPWT)—Experience of a Single Surgeon

Background: In this study, we aimed to analyze the clinical efficacy of closed-incision negative pressure wound therapy (CiNPWT) when combined with primary closure (PC) in a patient with pressure ulcers, based on one single surgeon’s experience at our medical center. Methods: We retrospectively reviewed the data of patients with stage III or IV pressure ulcers who underwent reconstruction surgery. Patient characteristics, including age, sex, cause and location of defect, comorbidities, lesion size, wound reconstruction methods, operation time, debridement times, application of CiNPWT to reconstructed wounds, duration of hospital stay, and wound complications were analyzed. Results: Operation time (38.16 ± 14.02 vs. 84.73 ± 48.55 min) and duration of hospitalization (36.78 ± 26.92 vs. 56.70 ± 58.43 days) were shorter in the PC + CiNPWT group than in the traditional group. The frequency of debridement (2.13 ± 0.98 vs. 2.76 ± 2.20 times) was also lower in the PC + CiNPWT group than in the traditional group. The average reconstructed wound size did not significantly differ between the groups (63.47 ± 42.70 vs. 62.85 ± 49.94 cm²), and there were no significant differences in wound healing (81.25% vs. 75.38%), minor complications (18.75% vs. 21.54%), major complications (0% vs. 3.85%), or mortality (6.25% vs. 10.00%) between the groups. Conclusions: Our findings indicate that PC combined with CiNPWT represents an alternative reconstruction option for patients with pressure ulcers, especially in those for whom prolonged anesthesia is unsuitable.

Ultrasound-guided Multiple Nerve Blocks: A Safe and Effective Anesthetic Modality in Geriatric Hip Fracture Patients

OBJECTIVES

The aim was to compare the feasibility of ultrasound-guided multiple nerve blocks (fascia iliaca compartment block+sacral plexus block+superior cluneal nerve block) with general anesthesia in geriatric hip fracture patients.

METHODS

Ninety-four patients were randomly divided into 2 groups: group N received ultrasound-guided multiple nerve blocks and group G received general anesthesia. Primary outcome measures included perioperative Pain Threshold Index (PTI) and Numerical Rating Scale. Secondary outcome measures comprised the following: (1) perioperative Delirium Index and Short Portable Mental Status Questionnaire; (2) perioperative Comfort Index; (3) perioperative opioid consumption (within 72 hours postoperatively); and (4) postoperative side effects (within 72 h postoperatively).

RESULTS

Eighty-seven patients completed the study. Baseline PTI was comparable between the groups. However, intraoperative PTI was significantly lower in group N than in group G. Preoperative and postoperative Comfort Index scores were comparable between the groups. Moderate delirium (24 to 72 h postoperatively) was significantly higher than the baseline in group G. Early moderate delirium (24 h postoperatively) was significantly higher in group G than in group N. Severe delirium was comparable between the groups and within each group. High intraoperative PTI was associated with high opioid consumption. The intravenous sufentanil dose in group G was twice of that in group N. Incidence of nausea and vomiting was similar between the groups.

DISCUSSION

Ultrasound-guided multiple nerve blockade may be an alternative to the common anesthetic procedures used for geriatric hip fracture patients. It provided satisfactory intraoperative pain management and reduced early postoperative cognitive disorders.

Regional Anaesthetic Techniques and Their Implications During the COVID Pandemic

The current pandemic has highlighted the need to protect both patients and medical staff. The increased use of regional anaesthesia as a primary anaesthetic modality for operations and other invasive procedures has limited the number of aerosol-generating procedures performed during general anaesthesia. Its use is further characterized by decreases in postoperative pain and length of hospitalization. This article provides an overview of regional anaesthetic techniques (peripheral nerve locks, epidural and spinal anaesthesia) and their uses during the COVID pandemic.

Preoperative and Perioperative Predictors of Length of Hospital Stay after Primary Total Hip Arthroplasty-Our Experience on 743 Cases

The aim of this retrospective investigation is to evaluate the correlation between several preoperative and perioperative factors and the length of hospital stay in patients that underwent elective total hip arthroplasty with overnight admission. Medical records of patients that underwent THA from the beginning of 2016 to the end of 2018 were retrospectively screened. Demographics, comorbidities, whole blood count, intraoperative details, and length of postoperative stay were retrieved. The association between clinical, laboratory and surgical factors and the length of hospital stay was explored by means of negative binomial and logistic regression models. The median length of postoperative hospital stay was four days (Inter Quartile Range, IQR 3, 5). After univariate regression a stepwise multivariate regression showed that operative time (p = 0.001), the preoperative serum creatinine (p < 0.001), the intraoperative blood loss (p = 0.04) and the use of an anterolateral approach (p < 0.001) were found to correlate significantly with the increase of the hospitalization length, while no significant correlation was found for all the other features. Multivariable model fitted through logistic regression (LOS below or over the median value of four days) had an Area Under the Curve (AUC) of 0.748. Our analysis suggests a significant role played by different preoperative and perioperative variables in influencing the length of hospital stay.

Neuraxial vs General Anesthesia: 30-Day Mortality Outcomes Following Transurethral Resection of Prostate

OBJECTIVE

To examine the occurrence of 30-day mortality, and other procedure related morbidities in cohorts of patient receiving neuraxial anesthesia (NAX) or general anesthesia (GA) in the setting of transurethral resection of the prostate (TURP). Historically, NAX has been recommended for patients undergoing TURP permitting monitoring of consciousness and early diagnosis of absorption-related hyponatremia. We aim to analyze a broader comparison of mortality and other associated morbidities regarding the form of anesthesia utilized.

METHODS

The National Surgical Quality Improvement Program (NSQIP) database was accessed and queried from January 2010 to December 2016 for TURP. 28,486 TURP cases were identified and further stratified by the type anesthesia administration, NAX 7,261 and GA 21,225. Chi-square analyses and Kaplan-Meier tests were performed for univariate comparisons. Using propensity score, data were optimally (1:1) matched to account for potential confounding variables. Outcomes were then compared for NAX vs. GA with a primary endpoint of 30-day mortality, followed by secondary endpoint of adverse outcomes reported per NSQIP.

RESULTS

Prior to matching, 30-day mortality was found to be 0.4% in the NAX cohort and 0.7% GA. 12,180 patients equally matched between the 2 groups. NAX was found to be superior to GA in terms of 30-day survival benefit (OR 0.55, 95% CI 0.33 -0.92, P <0.05), sepsis (OR 0.60, 95% CI 0.50 -0.73, P <0.001), and return to operating room (OR 0.76, 95% CI 0.60 -0.98, P <0.05) when comparing matched cohorts. NAX was associated with lower incidence of overall adverse clinical outcomes 12.4% vs 13.7% (P = 0.036).

CONCLUSION

NAX was found to have statistically relevant advantage for 30-day postoperative outcomes when compared to GA for TURP based on NSQIP database reporting.

Spinal Anesthesia Associated With Increased Length of Stay Compared to General Anesthesia for Ankle Open Reduction Internal Fixation: A Propensity-Matched Analysis

General and spinal anesthesia are both utilized for patients undergoing open reduction internal fixation of the ankle, but there are little data comparing early complication rates. The purpose of this study was to compare duration of surgery, length of stay, and rates of postoperative adverse events within 30 days in patients undergoing open reduction internal fixation of ankle fracture using spinal versus general anesthesia. Adult patients who underwent open reduction internal fixation of a closed ankle fracture from 2012 to 2016 were retrospectively identified from American College of Surgeons National Surgical Quality Improvement Program. Duration of surgery, length of stay, 30-day adverse events, and unplanned readmissions were compared between patients who received general anesthesia and spinal anesthesia. Propensity adjustment with respect to known risk factors for complications and adjunctive regional block was used to match patients. Of the 10,795 patients included after applying the inclusion and exclusion criteria, 9862 (91.36%) received general anesthesia and 933 (8.64%) received spinal anesthesia. Using propensity-scored matching, 841 patients in the spinal cohort were matched to 3364 patients in the general cohort. Spinal anesthesia was associated with increased length of stay (+0.5 days, 95% confidence interval 0.23-0.77, p < .001). There were no differences in the rates of major/minor complications, mortality, transfusions, unplanned readmissions, or duration of surgery. General anesthesia is predominantly used for fixation of ankle fractures. While spinal anesthesia is associated with lower complication rates in hip and knee surgery, we found that it is associated with increased length of stay in patients undergoing open reduction internal fixation of the ankle within 30 days of surgery.

General vs Neuraxial Anesthesia in Direct Anterior Approach Total Hip Arthroplasty: Effect on Length of Stay and Early Pain Control

BACKGROUND

Recent literature has suggested some benefits for neuraxial anesthesia (NA) as an alternative for general anesthesia (GA) for primary total hip arthroplasty patients. We examined the impact of NA vs GA on outcomes for patients undergoing direct anterior (DA) approach total hip arthroplasty (THA) in an institution with established rapid recovery protocols.

METHODS

A retrospective review was conducted for 500 consecutive THA patients from a single institution. Univariate analysis and multivariate linear regression were used to compare outcomes for THA patients receiving NA and GA.

RESULTS

There was a significant difference in length of stay with NA patients having a shorter length of stay (NA 32.7 hours vs GA 38.1 hours, P = .003). Patients receiving NA had significantly lower PACU morphine milligram equivalents (MME) (NA 10.2 MME vs GA 15.6 MME, P < .001) and reported a lower score on the PACU pain numeric rating scale (NA 2.1 vs GA 3.7, P < .001).

CONCLUSION

Neuraxial anesthesia is associated with decreased LOS, decreased PACU MME, and a lower PACU pain score for patients undergoing primary DA THA. These trends remained consistent when controlling for age, gender, BMI, and ASA.

Impact of Dexamethasone on Length of Stay and Early Pain Control in Direct Anterior Approach Total Hip Arthroplasty With Neuraxial Anesthesia

BACKGROUND

Dexamethasone has been shown to reduce postoperative pain and opioid consumption for total joint arthroplasty patients; however, its impact on patients who received neuraxial anesthesia (NA) is not well described. We examined the impact of perioperative dexamethasone on outcomes for patients undergoing direct anterior approach total hip arthroplasty (THA) under NA.

METHODS

A retrospective review was conducted for 376 THA patients from a single institution. Univariate analysis was used to compare postoperative outcomes for 164 THA patients receiving dexamethasone compared to 212 who did not receive dexamethasone.

RESULTS

No differences in age, gender, body mass index, or American Society of Anesthesiologists (ASA) Score were observed between the groups. Patients receiving perioperative dexamethasone reported statistically significantly lower postanesthesia care unit (PACU) pain numeric rating scale (Dexamethasone 1.6 vs No dexamethasone 2.3, P = .014) and received lower PACU morphine milligram equivalents (MME) (Dexamethasone 8.57 vs No dexamethasone 11.44, P < .001). Patients receiving dexamethasone had significantly shorter LOS (Dexamethasone 29.40 vs No dexamethasone 35.26 hrs., P < .001).

CONCLUSION

Perioperative dexamethasone is associated with decreased postoperative pain and narcotic consumption, and shorter length of stay for patients undergoing primary direct anterior approach THA with NA.

Using Lumbar X-Ray to Facilitate Modified Taylor's Approach of Spinal Anesthesia in an Elderly Patient With Scoliosis

In geriatric patients scheduled for hip or knee surgery, neuraxial anesthesia is a safe and effective anesthesia method and may be a better option than general anesthesia. Unfortunately, establishing neuraxial anesthesia is not always easy in this group of patients. Anatomical abnormalities, such as spinal stenosis, scoliosis, and narrowed interspaces, contribute to the difficulties that anesthesiologists face while performing these procedures. The classic Taylor’s approach targets the widest interspace, L5-S1, as the needle insertion site and accordingly has an increased success rate in difficult neuraxial anesthesia. As this technique historically relies solely on palpation, it might be difficult in patients with less prominent or distorted anatomic landmarks. Ultrasonography or fluoroscopy guidance may help to better target the epidural or subarachnoid space, but both have limitations due to equipment availability or provider expertise. The modified Taylor’s approach we propose in this case report is based on preoperative lumbar x-ray interpretation when point-of-care image guidance cannot be performed. By measuring on the patient’s preoperative lumbar x-ray, we successfully performed a modified Taylor's approach of spinal anesthesia on an elderly patient with severe scoliosis. She underwent open reduction and internal fixation (ORIF) of the left femur with satisfactory pain control and no complications.

Comparing the Effects of General Versus Regional Anesthesia on Postoperative Mortality in Total and Partial Hip Arthroplasty

Purpose

Total hip arthroplasty (THA) and partial hip arthroplasty (PHA) are performed in patients with hip joint dysfunction such as osteoarthritis or hip fractures and are associated with complications including mortality. There is a lack of evidence in the literature regarding whether the type of anesthesia (regional vs. general) is associated with increased postoperative mortality in patients undergoing hip arthroplasty. The present study compares early postoperative mortality between general or regional anesthesia administered to patients undergoing either THA or PHA.

Methods

A retrospective cohort was assembled using the 2015-2016 American College of Surgeons National Surgical Quality Improvement Program database. Adult patients undergoing hip arthroplasty under general or regional anesthesia were included. Patients were excluded if receiving any other type of anesthesia, as well as having an American Society of Anesthesiologists (ASA) physical status classification score ≥ 4, preoperative acute renal failure, severe congestive heart failure (CHF), chronic obstructive pulmonary disease (COPD), or ascites. Adjusted odds of 30 days all-cause postoperative mortality according to the type of anesthesia were estimated by fitting multiple logistic regression models that included potential confounders and effect modifiers.

Results

A total of 60,897 patients were included in the study. Given that the interaction between the type of anesthesia and the type of arthroplasty was statistically significant, separated models were fitted for each type of arthroplasty. There was no evidence of an association between type of anesthesia and postoperative mortality in hip arthroplasty patients regardless of whether the arthroplasty was partial (odds ratio {OR} = 0.85; confidence interval {CI} 0.59-1.22) or total (OR = 0.68; CI 0.43-1.08).

Conclusion

The overall early postoperative mortality in adult hip arthroplasty patients is low in the absence of risk factors such as severe CHF, COPD, ascites, acute renal failure, and ASA score of 4 or higher. Our findings suggest there is no association between the type of anesthesia received (general vs. regional) and early postoperative mortality rates in patients undergoing hip arthroplasty, regardless of type (total vs. partial).

Regional anaesthesia quality indicators for adult patients undergoing non-cardiac surgery: a systematic review

Improvement in healthcare delivery depends on the ability to measure outcomes that can direct changes in the system. An overview of quality indicators within the field of regional anaesthesia is lacking. This systematic review aims to synthesise available quality indicators, as per the Donabedian framework, and provide a concise overview of evidence-based quality indicators within regional anaesthesia. A systematic literature search was conducted using the databases MEDLINE, Embase, CINAHL and Cochrane from 2003 to present, and a prespecified search of regional anaesthesia society websites and healthcare quality agencies. The quality indicators relevant to regional anaesthesia were subdivided into peri-operative structure, process and outcome indicators as per the Donabedian framework. The methodological quality of the indicators was determined as per the Oxford Centre for Evidence-Based Medicine's framework. Twenty manuscripts met our inclusion criteria and, in total, 68 unique quality indicators were identified. There were 4 (6%) structure, 12 (18%) process and 52 (76%) outcome indicators. Most of the indicators were related to the safety (57%) and effectiveness (19%) of regional anaesthesia and were general in nature (60%). In addition, most indicators (84%) were based on low levels of evidence. Our study is an important first step towards describing quality indicators for the provision of regional anaesthesia. Future research should focus on the development of structure and process quality indicators and improving the methodological quality and usability of these indicators.

Perioperative strategies to reduce transfusion rates in one-stage bilateral total hip arthroplasty via direct anterior approach

Despite several blood management strategies available, blood transfusion rates following total hip arthroplasty remain high. Therefore, this study evaluated transfusion rates following bilateral hip arthroplasty via direct anterior approach using a multimodal blood loss management approach for 213 consecutive patients. All patients received standard surgical and post-operative procedures, with allogenic transfusion performed if hemoglobin was less than 8.0 g/dL with persistent clinical symptoms. Thirty-two patients (15%) required transfusion, with those patients significantly older and had lower pre-operative hemoglobin compared to non-transfusion patients. This transfusion rate was much lower than previous literature and could be an appropriate, multimodal blood loss management strategy.

Comparing Analgesic Effect of Intravenous Fentanyl, Femoral Nerve Block and Fascia Iliaca Block During Spinal Anesthesia Positioning in Elective Adult Patients Undergoing Femoral Fracture Surgery: a Randomized Controlled Trial

Background

Femoral fracture is the most painful bone injury and performing spinal anesthesia is extremely challenging due to very poor positioning unless we have a very good mode of analgesia. Intravenous strong opioids are commonly used but to date nerve blocks are also being utilized. The reliability and effectiveness of the aforementioned methods are not conclusive to practice worldwide. The objective of the study was to compare the analgesic effect of intravenous fentanyl, femoral nerve block (FNB) and fascia iliaca block (FICB) during positioning patients with femoral fracture for spinal anesthesia.

Methods

A randomized controlled trial study was conducted on 72 elective adult patients with femoral fracture aged 18–65 years and ASA I and II those were allocated randomly into three groups. The intravenous fentanyl (IVFE) group received 1µg/kg IV fentanyl, FNB group received nerve stimulator guided FNB with 30 mL of 1% lidocaine with adrenaline and FICB group received FICB with 30 mL of 1% lidocaine with adrenaline. Pain intensity in numeric rating score (NRS), time to perform spinal anesthesia, quality of positioning and patient acceptance were assessed. SPSS version 26 and Kruskal–Wallis test were used to analyze data and p value <0.05 was considered significant.

Results

NRS Pain score during positioning was significantly lower in FNB and FICB groups than IVFE group [median (IQR)]; 2 (1–2.5), 2 (2–3)) vs. 3 (3–4) respectively; P<0.001 and P=0.001. However, FNB and FICB groups were not significantly different with (P=1.000). Time to perform spinal anesthesia was significantly longer in IVFE group 9.5 (9–10) minutes than both FNB and FICB groups 7 (6–8), 8 (6–8) respectively, P<0.001. The quality of positioning was significantly lower in the IVFE group than both FNB and FICB groups (P<0.001).

Conclusion

Preoperative FNB and FICB reduce pain score during positioning, shorten time to perform spinal anesthesia, better patient positioning and higher patient acceptance in a patient undergoing elective femoral bone fracture surgery.

Spinal versus general anesthesia for outpatient joint arthroplasty: can the evidence keep up with the patients?

Total joint arthroplasty (TJA) is transitioning to be an outpatient rather than an inpatient procedure under national and institutional pressures to increase volumes while reducing hospital costs and length of stay. Innovative surgical and anesthesia techniques have allowed for earlier ambulation and physical therapy participation, maximizing the chance that an appropriately selected patient may be discharged within a day of surgery. The choice of anesthesia type is a modifiable factor that has a major impact on both surgical outcomes and discharge readiness. Recent large database studies have provided evidence for improved outcomes, including decreased mortality, with the use of spinal anesthesia. However, few randomized, controlled trials exist and database studies have limitations. Modern general anesthesia techniques, including total intravenous anesthesia and infusions targeted to anesthetic depth, may make some of these differences insignificant, especially when newer regional anesthesia and local infiltration analgesia techniques are incorporated into TJA enhanced recovery protocols. Multimodal analgesia for all TJA patients may also help minimize differences in pain. Perhaps even more important than anesthesia technique is the proper selection of patients likely to meet the necessary milestones for early discharge. In this article, we provide two contrasting viewpoints on the optimal primary anesthetic for outpatient TJA.
