Front Med (Lausanne) 2023; 10:1219222. [PMID: 37497272 PMCID: PMC10366448 DOI: 10.3389/fmed.2023.1219222] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/08/2023] [Accepted: 06/29/2023] [Indexed: 07/28/2023] Open
Abstract
Objectives To explore the risk factors associated with postoperative hypoxaemia in elderly patients who have recovered from coronavirus disease (COVID-19) and underwent hip fracture surgery in the short term. Design Multicentre retrospective study. Setting The study was performed in three first 3A-grade hospitals in China. Participants A sequential sampling method was applied to select study participants. Medical records of 392 patients aged ≥65 years who had recovered from COVID-19 and underwent hip fracture surgery at three hospitals in China between 1 November, 2022, and 15 February, 2023, were reviewed. Interventions Patients were assigned to hypoxaemia or non-hypoxaemia groups, according to whether hypoxaemia occurred after surgery. Univariate and multivariate logistic regression analyses were used to identify independent risk factors for postoperative hypoxaemia. Results The incidence of postoperative hypoxaemia was 38.01%. Statistically significant differences were found between the two groups in terms of age, body mass index (BMI), American Society of Anesthesiologists (ASA) classification, presence of expectoration symptoms, preoperative hypoxaemia, chronic obstructive pulmonary disease, pulmonary inflammation, time between recovery from COVID-19 and surgery, anaesthetic mode, surgical procedure, intraoperative blood loss, intraoperative infusion, duration of surgery, and length of hospital stay (p < 0.05). Furthermore, patients with BMI ≥28.0 kg/m2, expectoration symptoms, presence of preoperative hypoxaemia, ASA classification III, time between recovery from COVID-19 and surgery ≤2 weeks, and general anaesthesia were potential risk factors for postoperative hypoxaemia. Conclusion Obesity, expectoration symptoms, preoperative hypoxaemia, ASA classification III, time between recovery from COVID-19 and surgery ≤2 weeks, and general anaesthesia were potential risk factors for postoperative hypoxaemia in elderly patients who recovered from COVID-19 and underwent hip fracture surgery in the short term.

Ultrasound-guided anterior iliopsoas muscle space block effectively reduces intraoperative hypotension in elderly adults undergoing hip surgery: A randomised controlled trial. Front Mol Neurosci 2023; 16:1119667. [PMID: 36756613 PMCID: PMC9900129 DOI: 10.3389/fnmol.2023.1119667] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/09/2022] [Accepted: 01/09/2023] [Indexed: 01/24/2023] Open
Abstract
Background Hypotension often occurs during hip surgery in elderly adults with conventional posterior lumbosacral plexus block. Purpose We conducted a randomised controlled trial to determine if simple iliopsoas space block can lower the incidence of intraoperative hypotension (IOH) and provide sufficient perioperative pain relief during hip fracture surgery in elderly adults. Methods Patients undergoing surgery for elderly hip fracture were randomised to receive either an anterior iliopsoas space block with a lateral femoral cutaneous nerve block or a posterior lumbosacral plexus block. The primary outcome was a composite measure of IOH incidence comprising frequency, absolute and relative hypotension durations. Results Compared to the posterior group, the iliopsoas space block group had a decreased median frequency of IOH [1.09 (0-2. 14) vs. 3 (1.6-4.8), p = 0.001, respectively] along with lower absolute [5 (0-10) min] and relative [minutes below systolic blood pressure of 100 mmHg in % of total anaesthesia time, 6.67 (0-7.65)] duration of IOH compared to the posterior group [35 (10-45) min, p = 0.008; 37.6 (12.99-66.18), p = 0.004, respectively]. The median pain levels in the post-anaesthesia care unit and median intraoperative sufentanil usage were comparable between the iliopsoas space group [2 (1-3); 8 (6-10) μg] and posterior group [1 (0-3); 5 (5-8) μg]. Thermal imaging revealed that the limb injected with the iliopsoas space block had a higher skin temperature than the unblocked limb in the sacral plexus innervated region. Conclusion A single iliopsoas space block lowers the IOH incidence and provides comparable perioperative analgesia to conventional lumbosacral plexus block.

JOURNAL OF ENVIRONMENTAL AND PUBLIC HEALTH 2022; 2022:3603949. [PMID: 36176970 PMCID: PMC9514925 DOI: 10.1155/2022/3603949] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Download PDF] [Subscribe] [Scholar Register] [Received: 08/08/2022] [Revised: 09/01/2022] [Accepted: 09/12/2022] [Indexed: 11/17/2022]
Abstract
Objective Surgical reduction is the leading approach to patients with lower extremity fractures. The options of anesthetic drugs during surgery are of great significance to postoperative recovery of patients. There is no consensus on the optimum anesthesia method for patients undergoing lower extremity fracture surgery. Our study is aimed at investigating the impacts of nerve block combined with general anesthesia on perioperative outcomes of the patients. Methods In this retrospective study, 48 patients experienced general anesthesia only, and 42 patients received never block combined with general anesthesia. The perioperative hemodynamics was recorded, including mean arterial pressure (MAP), oxygen saturation of blood (SpO2), and heart rate (HR). Visual analogue scale (VAS) and Montreal Cognitive Assessment (MoCA) were carried out to evaluate postoperative pain and cognitive status. Furthermore, adverse reactions and recovery condition were observed between the patients receiving different anesthesia methods. Results At 15 minutes and 30 minutes after anesthesia, as well as 5 minutes after surgery, significant lower MAP was observed in the patients treated with general anesthesia (83.04 ± 8.661, 79.17 ± 9.427, 86.58 ± 8.913) compared to those receiving never block combined with general anesthesia (90.43 ± 4.618, 88.74 ± 6.224, 92.21 ± 4.015) (P < 0.05), and compared with general anesthesia group (68.5 ± 7.05, 69.63 ± 7.956, 72.75 ± 8.446), the combined anesthesia group (73.52 ± 9.451, 74.17 ± 10.13, 77.62 ± 9.768) showed obvious higher HR (P < 0.05). No significant difference in SpO2 was found between the two groups at multiple time points (P > 0.05). As for the score of VAS and MoCA, remarkably lower VAS and higher MoCA at 6 h, 12 h and 24 h after surgery were presented in the combined anesthesia group compared to general anesthesia group (P < 0.05). At 24 h after surgery, the two groups showed normal cognitive function (26.33 ± 0.7244 vs. 28.55 ± 0.7392). Incidence of nausea and vomiting in the combined anesthesia group was lower than that of the general anesthesia group (P < 0.05). The time to out-of-bed activity and hospital stay were shorter in the combined anesthesia group compared with general anesthesia (P < 0.05). Conclusion The application of never block combined with general anesthesia contributed to the stability of hemodynamics, alleviation of postoperative pain and cognitive impairment, along with decrease in adverse reactions and hospital stay in the patients with lower extremity fractures.

Zhang Q, Ling M, Wang X, Cui D. A Comparison of Two Peripheral Nerve Blocks Combined With General Anesthesia in Elderly Patients Undergoing Arthroplasty for Hip Fractures: A Pilot Randomized Controlled Trial. Front Surg 2022; 9:715422. [PMID: 35252320 PMCID: PMC8891216 DOI: 10.3389/fsurg.2022.715422] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/26/2021] [Accepted: 01/14/2022] [Indexed: 11/23/2022] Open
Abstract
Background Combined anesthesia can be a promising option for hip surgery when neuraxial anesthesia is contraindicated. Lumbar and sacral plexus blocks, and femoral nerve and lateral femoral cutaneous (LFC) nerve blocks in combination with general anesthesia (GA) are commonly used in elderly patients undergoing arthroplasty for hip fracture surgery. However, no study has compared these two anesthetic strategies in the perioperative period. Methods A total of 41 elderly patients scheduled for arthroplasty for hip fracture surgery were randomized into group A (n = 20) and group B (n = 21). Group A received femoral nerve block, LFC nerve blocks, and GA, and group B received lumbar plexus block, sacral plexus block, and GA. Primary outcomes were incidences of hemodynamic events and changes in blood pressure (BP) and heart rate (HR). Secondary outcomes included time and drug consumption, infusion and bleeding volume, eyes opening time after surgery, and postoperative quality recovery rate. Results Compared with group B, group A showed a lower incidence of intraoperative hypotension (p < 0.001), higher BP [including mean arterial pressure (MAP), systolic BP (SBP), and diastolic BP (DBP)] following induction (IN), and higher HR from mid-surgery. Time required for nerve blockade (p < 0.001) and ephedrine consumption was significantly shorter in group A (p < 0.001), while sufentanil consumption was higher as compared to group B (p = 0.002). No significant differences in other intraoperative parameters and postoperative quality recovery rate were reported during the observation. Conclusion Our pilot data indicate that compared with lumbar and sacral plexus blocks, femoral nerve and LFC nerve blocks may provide more stable intraoperative hemodynamics and a comparable postoperative recovery for elderly patients undergoing arthroplasty for hip fracture under GA. Further studies with a larger sample size are needed to derive stronger evidence.

Safety of Different Anesthesia Methods Combined with Intravenous Fast Channel Anesthesia in Lower Extremity Orthopedic Surgery of the Elderly. EVIDENCE-BASED COMPLEMENTARY AND ALTERNATIVE MEDICINE 2021; 2021:9787879. [PMID: 34745307 PMCID: PMC8568556 DOI: 10.1155/2021/9787879] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 09/10/2021] [Accepted: 10/04/2021] [Indexed: 12/03/2022]
Abstract
Objective To compare the safety of different anesthesia methods combined with intravenous fast channel anesthesia in elderly lower extremity surgery and the effect on postoperative outcome. Methods A total of 106 elderly patients who underwent lower extremity orthopedic surgery in our hospital from February 2018 to February 2021 were selected and randomly divided into the control group (n = 53) and the observation group (n = 53) according to random number table. All patients received intravenous fast-track anesthesia. On this basis, the control group received spinal-epidural anesthesia, and the observation group received iliac fascial space block on the affected side combined with sciatic nerve block. The operation conditions, blood pressure and heart rate changes, awakening time, postoperative ICU admission rate, and complications were compared between the two groups. Results There was no statistical difference in the success rate of one-time operation between the two groups (P > 0.05). The times of using analgesics and vasoactive drugs and the dosage of propofol in the observation group during the operation were lower than those in the control group, and the difference was statistically significant (P < 0.05). At T2, T3, and T4, the levels of HR, DBP, and SBP in the observation group were lower than those in the control group, and the difference was statistically significant (P < 0.05). After operation, the time of awakening, spontaneous breathing recovery, and extubation in the observation group were lower than those in the control group, and the difference were statistically significant (P < 0.05). The incidence of complications in the observation group was lower than that in the control group, the cognitive impairment was the most significant one in the incidence of single complication, and the difference was statistically significant (P < 0.05). Conclusion Based on the combined intravenous fast channel anesthesia, the operation difficulty of the affected side iliac fascial space block combined with sciatic nerve block is the same as that of spinal-epidural anesthesia. It has a higher success rate of one operation, better analgesic and anesthetic effects during the operation, and little effect on blood flow of patients. It can maintain relatively stable heart rate and blood pressure and does not easily cause postoperative complications. Its safety is higher than that of spinal-epidural anesthesia.

Abstract
BACKGROUND Ultrasound-guided posterior lumbar plexus block is widely used for hip fracture surgery but it requires a change of position, which may be painful. OBJECTIVES Our primary objective was to describe a new technique, the anterior iliopsoas muscle space block, which can be performed in the supine position, and to test the hypothesis that its analgesia for hip surgery was similar to that of the traditional posterior lumbar plexus block. DESIGN Randomised, double-blind study. SETTING Shanghai 6th People's Hospital, China, from February to August 2019. PATIENTS Forty-eight patients scheduled for unilateral hip fracture surgery were included in the study. The exclusion criteria were infection at the puncture site, history of hip surgery, pre-existing neurological deficits of the lower extremity, contraindications for regional anaesthesia, allergy to local anaesthetics, coagulopathy, abuse of medicine or alcohol, or daily consumption of analgesics. INTERVENTIONS Patients were randomised to receive a lateral sacral plexus block with either an anterior iliopsoas muscle space block or a posterior lumbar plexus block, using 0.33% ropivacaine (30 ml each). MAIN OUTCOME MEASURES The main outcome was verbal numerical scale (VNS) pain intensity 1 h after surgery in the postanesthesia care unit, and the secondary outcome was the dose of intra-operative fentanyl. The differences in VNS scores and fentanyl use between the groups were analysed. RESULTS Based on previous work, we considered a difference (confidence interval [CI]) of 1.6 on the VNS to be significant. The median [IQR] pain scores in postanesthesia care unit were similar in the anterior 0 [0 to 3] and posterior groups 1.5 [0 to 3]. The median scores for intra-operative fentanyl use were similar in the anterior 20 [10 to 42.5] μg and posterior groups 15 [0 to 50] μg (P = 0.34). The difference in the median pain score at-rest was NS: anterior group 0.5 [0 to 5], posterior group 0 [0 to 2], median difference -0.5 (95% CI -2 to 0). The median post to preblock difference in VNS was higher in the anterior -0.5 [-2 to 0] than in the posterior group 0 [-1.25 to 0], median difference 0.5 (95% CI 0 to 1). The median block onset time was longer in the anterior 11 [6 to 14.25] min than in the posterior group 6 [4.75 to 8] min (P = 0.002), median difference -5 (95% CI -7 to -1). CONCLUSION The anterior iliopsoas muscle space block had the same effect as the posterior lumbar plexus block on peri-operative analgesia for hip surgery, but with a longer onset time. Therefore, anterior iliopsoas muscle space block can be recommended as a routine technique for hip and lower limb procedures. TRIAL REGISTRATION http://www.chictr.org.cn identifier: ChiCTR1900021214.

Abstract
BACKGROUND This review was published originally in 1999 and was updated in 2001, 2002, 2009, 2017, and 2020. Updating was deemed necessary due to the high incidence of hip fractures, the large number of official societies providing recommendations on this condition, the possibility that perioperative peripheral nerve blocks (PNBs) may improve patient outcomes, and the major role that PNBs may play in reducing preoperative and postoperative opioid use for analgesia. OBJECTIVES To compare PNBs used as preoperative analgesia, as postoperative analgesia, or as a supplement to general anaesthesia versus no nerve block (or sham block) for adults with hip fracture. Outcomes were pain on movement at 30 minutes after block placement, acute confusional state, myocardial infarction, chest infection, death, time to first mobilization, and costs of an analgesic regimen for single-injection blocks. We undertook the update to look for new studies and to update the methods to reflect Cochrane standards. SEARCH METHODS For the updated review, we searched the following databases: the Cochrane Central Register of Controlled Trials (CENTRAL; 2019, Issue 11), in the Cochrane Library; MEDLINE (Ovid SP, 1966 to November 2019); Embase (Ovid SP, 1974 to November 2019); and the Cumulative Index to Nursing and Allied Health Literature (CINAHL) (EBSCO, 1982 to November 2019), as well as trial registers and reference lists of relevant articles. SELECTION CRITERIA We included randomized controlled trials (RCTs) assessing use of PNBs compared with no nerve block (or sham block) as part of the care provided for adults 16 years of age and older with hip fracture. DATA COLLECTION AND ANALYSIS: Two review authors independently screened new trials for inclusion, assessed trial quality using the Cochrane Risk of Bias-2 tool, and extracted data. When appropriate, we pooled results of outcome measures. We rated the certainty of evidence using the GRADE approach. MAIN RESULTS We included 49 trials (3061 participants; 1553 randomized to PNBs and 1508 to no nerve block (or sham block)). For this update, we added 18 new trials. Trials were published from 1981 to 2020. Trialists followed participants for periods ranging from 5 minutes to 12 months. The average age of participants ranged from 59 to 89 years. People with dementia were often excluded from the included trials. Additional analgesia was available for all participants. Results of 11 trials with 503 participants show that PNBs reduced pain on movement within 30 minutes of block placement (standardized mean difference (SMD) -1.05, 95% confidence interval (CI) -1.25 to -0.86; equivalent to -2.5 on a scale from 0 to 10; high-certainty evidence). Effect size was proportionate to the concentration of local anaesthetic used (P = 0.0003). Based on 13 trials with 1072 participants, PNBs reduce the risk of acute confusional state (risk ratio (RR) 0.67, 95% CI 0.50 to 0.90; number needed to treat for an additional beneficial outcome (NNTB) 12, 95% CI 7 to 47; high-certainty evidence). For myocardial infarction, there were no events in one trial with 31 participants (RR not estimable; low-certainty evidence). From three trials with 131 participants, PNBs probably reduce the risk for chest infection (RR 0.41, 95% CI 0.19 to 0.89; NNTB 7, 95% CI 5 to 72; moderate-certainty evidence). Based on 11 trials with 617 participants, the effects of PNBs on mortality within six months are uncertain due to very serious imprecision (RR 0.87, 95% CI 0.47 to 1.60; low-certainty evidence). From three trials with 208 participants, PNBs likely reduce time to first mobilization (mean difference (MD) -10.80 hours, 95% CI -12.83 to -8.77 hours; moderate-certainty evidence). One trial with 75 participants indicated there may be a small reduction in the cost of analgesic drugs with a single-injection PNB (MD -4.40 euros, 95% CI -4.84 to -3.96 euros; low-certainty evidence). We identified 29 ongoing trials, of which 15 were first posted or at least were last updated after 1 January 2018. AUTHORS' CONCLUSIONS: PNBs reduce pain on movement within 30 minutes after block placement, risk of acute confusional state, and probably also reduce the risk of chest infection and time to first mobilization. There may be a small reduction in the cost of analgesic drugs for single-injection PNB. We did not find a difference for myocardial infarction and mortality, but the numbers of participants included for these two outcomes were insufficient. Although randomized clinical trials may not be the best way to establish risks associated with an intervention, our review confirms low risks of permanent injury associated with PNBs, as found by others. Some trials are ongoing, but it is unclear whether any further RCTs should be registered, given the benefits found. Good-quality non-randomized trials with appropriate sample size may help to clarify the potential effects of PNBs on myocardial infarction and mortality.

Abstract
BACKGROUND There is no consensus on the optimal anesthesia method for intertrochanteric fracture surgeries in elderly patients. Our study aimed to compare the hemodynamics and perioperative outcomes of general anesthesia with endotracheal intubation, combined spinal-epidural anesthesia, and general anesthesia with laryngeal mask airway (LMA) and nerve block for intertrochanteric fracture surgeries in elderly patients. METHODS This is a retrospective study of 75 patients aged > 60 years scheduled for intertrochanteric fracture surgeries with general anesthesia with intubation (n = 25), combined spinal-epidural anesthesia (n = 25), and general anesthesia with LMA and nerve block (n = 25). The intraoperative hemodynamics were recorded, and the maximum variation rate was calculated. Postoperative analgesic effect was evaluated using the visual analog scale (VAS). Postoperative cognitive status was assessed using the Mini-Mental State Exam (MMSE). RESULTS The maximum variation rate of intraoperative heart rate, systolic blood pressure, diastolic blood pressure differed significantly between the three groups (general anesthesia with intubation > combined spinal-epidural anesthesia > general anesthesia with LMA and nerve block). The VAS scores postoperative 2 h, 4 h, 6 h, and 8 h also differed significantly between the three groups (general anesthesia with intubation > combined spinal-epidural anesthesia > general anesthesia with LMA and nerve block). The VAS scores postoperative 24 h were significantly lower in the general anesthesia with LMA/nerve block group than the general anesthesia with intubation group and the combined spinal-epidural anesthesia group. The MMSE scores postoperative 15 min and 45 min differed significantly between the three groups (general anesthesia with intubation < combined spinal-epidural anesthesia < general anesthesia with LMA and nerve block). The MMSE scores postoperative 120 min in the general anesthesia with intubation group were the lowest among the three groups. There was no significant difference in the incidence of respiratory infection postoperative 24 h, 48 h, and 72 h between the three groups. CONCLUSION Compared to general anesthesia with intubation and combined spinal-epidural anesthesia, general anesthesia with LMA and nerve block had better postoperative analgesic effect and less disturbances on intraoperative hemodynamics and postoperative cognition for elderly patients undergoing intertrochanteric fracture surgeries.
