Abstract
PURPOSE OF REVIEW To review the benefits, risks, and contraindications of traditional and new anesthesia approaches for hip fracture surgery and describe what is known about the impact of these approaches on postoperative outcomes. RECENT FINDINGS This review describes general and spinal anesthesia, peripheral nerve block techniques used for pain management, and novel, local anesthesia approaches which may provide significant benefit compared with traditional approaches by minimizing high-risk induction time and decreasing respiratory suppression and short- and long-term cognitive effects. Hip fracture surgery places a large physiologic stress on an already frail patient, and anesthesia choice plays an important role in managing risk of perioperative morbidity. New local anesthesia techniques may decrease morbidity and mortality, particularly in higher-risk patients.

Ultrasound-guided adductor canal block is superior to femoral nerve block for early postoperative pain relief after single-bundle anterior cruciate ligament reconstruction with hamstring autograft. J Med Ultrason (2001) 2023; 50:433-439.

Abstract
PURPOSE This study aimed to compare the combination of a lateral femoral cutaneous nerve (LFCN) block with a femoral nerve block (FNB) and an adductor canal block (ACB) for postoperative pain control in patients undergoing anterior cruciate ligament (ACL) reconstruction with hamstring autograft. METHODS A non-randomized, prospective, controlled clinical trial was conducted. The FNB and ACB groups consisted of 41 and 40 patients, respectively. Thirty minutes prior to surgery, the patients received an ultrasound-guided LFCN block either with FNB or ACB. The following values were recorded and compared between the two groups: duration of surgery, pain management during surgery (including total amount of fentanyl administered), and numerical rating scale (NRS) scores at 30 min and 4, 8, 12, 24, 48, and 72 h after surgery. Factors affecting pain relief (NRS < 2) were evaluated, including block type, total amount of fentanyl administered, duration of surgery, age, sex, body mass index, and postoperative suppository use. Significant factors predicting pain relief were determined using the Cox proportional hazard regression model. RESULTS There were no significant differences in pain management during the surgery. Pain scores were significantly lower in the ACB group at 30 min, 4 h, 24 h, and 48 h after surgery. The Cox proportional hazard regression model identified ACB as a significant factor for pain relief (hazard ratio: 1.88; 95% confidence interval: 1.12-3.13; p = 0.018). CONCLUSION The combination of ACB with LFCN block during ACL reconstruction significantly reduced pain in the early postoperative period compared to FNB with LFCN block.

The Feasibility of the Ultrasound-Guided Femoral Nerve Block Procedure with Low-Dose Local Anesthetic in Intracapsular and Extracapsular Hip Fractures. J Emerg Med 2020; 58:553-561. [PMID: 32070647 DOI: 10.1016/j.jemermed.2019.12.033] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/12/2019] [Revised: 12/25/2019] [Accepted: 12/25/2019] [Indexed: 11/25/2022]
Abstract
BACKGROUND The local anesthetic dosages used in the current literature in regional applications of local anesthetics are frequently high for surgical purposes, and there are no sufficient dosage studies for emergency department (ED) management. OBJECTIVES The aim of this study was to determine the success of lower local anesthetic dosages capable of reducing costs and excessive exposure to drugs in pain control in patients with femoral neck fractures (FNFs) in the ED. METHODS Patients ≥65 years of age with FNFs and reporting Wong-Baker Pain Rating Scales scores ≥8 were included in this prospective, interventional study. Patients underwent ultrasound-guided regional femoral block with 5 mL 2% prilocaine. Pain scores before the procedure and at 30 min and 2 h postprocedure were compared with the Friedman test and Wilcoxon test with Bonferroni correction. RESULTS Forty patients, 20 with intracapsular and 20 with extracapsular FNFs, were enrolled. The initial pain scores of patients with both intra- and extracapsular fractures were 8 (range 8-10). A statistically significant 50% decrease in pain scores was observed in both groups 30 min after the regional block procedure (p < 0.001). A statistically significant 75% decrease in pain scores was observed in both groups 2 h after the regional block procedure (p < 0.001). No statistically significant difference was determined in the change in 30-min and 2-h pain scores between the groups. CONCLUSIONS The administration of 5 mL 2% prilocaine for pain control in FNFs in elderly patients in the ED can reduce systemic analgesic requirements by establishing effective analgesia in both intracapsular and extracapsular fractures.

Abstract
PURPOSE To evaluate the usefulness of ultrasound-guided nerve blockade in patellar fracture surgery. MATERIALS AND METHODS Twenty-three patients who underwent metal fixation under ultrasound-guided lower extremity blockade after diagnosis of patellar fracture from July 2011 to June 2012 were enrolled in this study. Under ultrasound guidance, femoral nerve, lateral femoral cutaneous nerve, obturator nerve, and sciatic nerve blockades were performed. For evaluation of anesthesia, interference with overall surgery, such as intraoperative knee pain and tourniquet pain, was checked. Individual anesthetic complications, satisfaction with nerve blocks, and choice of future anesthesia method were investigated. RESULTS Nineteen patients underwent surgery without any pain and 4 patients with mild pain. Satisfaction was excellent in 17 patients, good in 5, and unsatisfactory in 1. No complications such as infection or nerve injury occurred. In terms of selection of future anesthesia, 22 patients chose a nerve blockade of the lower extremity under ultrasound guidance, and one chose general anesthesia. CONCLUSIONS Overall, ultrasound-guided nerve block of the lower extremity for patellar fracture surgery showed satisfactory results. Therefore, it could be a useful method to prevent complications associated with general or spinal anesthesia.

Abstract
The incidence of hip dislocation can vary based on factors including age and patient co-morbidities. Prosthetic hip dislocations present a particularly difficult challenge. Although many cases are treated in the emergency setting using procedural sedation for reduction, some may require general anesthesia. We report two cases in which lumbar plexus blockade was used as the primary means for successful hip prosthesis dislocation reduction.

Abstract
This study assessed the efficacy and duration of postoperative analgesia after continuous sciatic nerve block with and without continuous "3-in-1" block with bupivacaine after unilateral total knee arthroplasty and determined catheter tip correlation with analgesia. Thirty patients were randomized into 2 groups. Results suggested significantly reduced pain and rescue analgesic requirement in combined sciatic and 3-in-1 (group TS) compared to 3-in-1 group alone (group T). The postoperative pain-free interval and satisfaction score was significantly higher in the combined group (P < .05). The percentage of catheters in the ideal position was 53.3% for 3-in-1 and 93.3% for sciatic nerve. In conclusion, continuous sciatic nerve block when added to continuous 3-in-1 block provides a better quality of analgesia with lesser requirements of rescue analgesics without the need for routine radiographic conformation.

Abstract
This article provides a succinct and complete method for the clinical evaluation of the hip. Included are descriptions of examination tests as well as their relationships to possible pathology of the hip. The examination is divided into five stages: seated, standing, supine, lateral, and prone; with a total of 11 assessment points. The method for evaluation outlined will assist physicians in determining the location and etiology of presenting hip pathologies. As with any examination, practice and repetition are essential to gain an appreciation of what constitutes a normal as well as an abnormal examination.

Abstract
BACKGROUND Gaps in the distribution area of the lateral femoral cutaneous nerve (LFCN) are assumed to be the reason for pain caused by a thigh tourniquet when performing a femoral nerve (FN) block according to Winnie. The aim of the study was to evaluate if a direct single blockade of the LFCN in patients undergoing knee surgery resulted in a better tolerance to the tourniquet with equally good analgesic quality during surgery. METHODS A total of 40 patients undergoing knee arthroscopy received a proximal blockade of the sciatic nerve and randomly either an FN or an LFCN block. Practicability, onset time, quality of sensory and motor block, and clinical effectiveness during tourniquet and surgery were assessed. RESULTS Stimulation time was significantly longer in the LFCN than in the FN group. Quality of sensory and motor block was worse in the LFCN than the NF group. Of the LFCN patients 65% indicated troublesome paraesthesia or pain when a tourniquet was placed, compared to 35% of the FN patients. Of the LFCN patients 50% had pain during cutaneous incision, compared to none of the FN group. During the course of surgery, 70% of the LFCN patients needed supplemental systemic analgesia, but this was required by only 30% of the FN group. CONCLUSION An LFCN block is not a suitable alternative to an FN block for regional anaesthesia. For patients with contraindications for an FN block according to Winnie (e.g. vessel surgery in the groin) other more effective methods are available.

Abstract
BACKGROUND Until recently only small series of psoas compartment blocks (PCB) in children have been reported. A high incidence of epidural spread as an important side effect was noted. A series of 100 consecutive blocks using new standardized landmarks is reported. METHODS In 100 consecutive children (5.9-106 kg) PCB was performed using a nerve stimulator. In the lateral position, the needle was inserted between the medial 2/3 and the lateral 1/3 on a line from the spinous process of L4 to the posterior superior iliac spine. The blocks were performed by residents in training under supervision of one specific designated pediatric anesthetist. RESULTS All blocks were clinically successful. In 64% only one attempt was necessary, in 26 patients two attempts were necessary and in 10 patients more than two attempts were necessary. In 16% a vascular puncture occurred. In one patient with a dense unilateral block a partial epidural spread occurred. No serious complications were observed during the perioperative period. CONCLUSIONS The described new technique has a very high success rate with no relevant side effects. Although only one case of epidural spread occurred, PCB remains an invasive technique with the potential for serious complications.

Abstract
Continuous femoral "3-in-1" nerve blocks are commonly used for analgesia after total knee arthroplasty (TKA). There are conflicting data as to whether additional sciatic blockade is needed. Our routine use of both continuous femoral (CFI) and sciatic (CSI) peripheral nerve blocks was changed because of concerns that sciatic blockade, and its motor consequences in particular, might obscure diagnosis of perioperative sciatic nerve injury. The revised protocol includes placing single-shot blocks and perineural catheters at both sites, but infusing local anesthetic postoperatively only in the CFI. CSI is reserved for patients having poorly controlled posterior knee or calf pain. A sample group of 12 patients treated with this protocol was followed. Ten of 12 patients required use of the CSI. Within 1 h of a 5-10 mL CSI bolus of 0.2% ropivacaine and beginning an infusion of the same drug at 5 mL/h, patients' median pain by verbal analog scale decreased from 7.5 to 2.0 (mean scores from 7.3 to 2.4). It was possible to maintain this level of analgesia until the third postoperative day when catheters were discontinued. Our experience suggests that, in most patients, adequate analgesia after TKA cannot be achieved with CFI alone and that the addition of CSI renders a significant improvement in analgesia.

Abstract
UNLABELLED Continuous three-in-one block is widely used for postoperative analgesia after proximal lower limb surgery, but location of the catheter has not been well addressed in the literature. We prospectively studied, in 100 patients, the characteristics of catheter threading under the iliac fascia and the correlations between catheter tip location and effective sensory and motor blockade of the three principal nerves of the lumbar plexus. Postoperatively, in conscious patients, 16 to 20 cm of a catheter was placed in the fascial sheath after femoral nerve location with a nerve stimulator. Contrast media (3 mL Iopamidol 390) was injected, and the catheter tip was located by means of an anteroposterior pelvic radiograph. An equal-volume mixture of 0.5% bupivacaine/2% lidocaine with epinephrine (30 mL) was injected through the catheter. Patient and catheter-insertion characteristics were noted. Thirty minutes after injection, sensory blockade was evaluated in the cutaneous territories of the lateral femoral cutaneous, femoral, and obturator nerves, along with motor blockade of the last two nerves. Pain scores at 30 min were also recorded. Seven block failures were noted. The tip of the catheter reached the lumbar plexus (Group 1) in 23% of the patients and lay deep to the medial (Group 2) or lateral (Group 3) part of the fascia iliaca in 33% and 37% of the patients, respectively. Demographic data and catheter threading characteristics were comparable among the groups. A three-in-one block was noted in 91% of Group 1 patients, but in only 52% and 27% of Group 2 and 3 patients, respectively (P < 0.05). Comparing Group 2 and 3 patients, sensory block was achieved in respectively 100% and 94% for the femoral nerve, 52% and 94% for the lateral femoral cutaneous nerve (P < 0.05), and 82% and 27% for the obturator nerve (P < 0.05). Visual analog scale pain scores on movement were significantly lower in Group 1 patients (P < 0.05). We conclude that during a continuous three-in-one block, the threaded catheter rarely reached the lumbar plexus. The quality of sensory and motor blockade and initial pain relief depend on the location of the catheter tip under the fascia iliaca. IMPLICATIONS The course of a continuous three-in-one block catheter is unpredictable. Only 23% of the catheters lie near the lumbar plexus. The success of sensory and motor blocks, as well as postoperative analgesia, depend on the position of the catheter under the fascia iliaca.

Abstract
Lower extremity nerve blocks have not become as popular as upper extremity blocks for anesthesia; however, the use of lower extremity nerve blocks will become more widespread, as teaching programs are now providing more regional anesthesia experiences for their trainees so that the anesthesia provider will have the familiarity to use these blocks. To increase the enthusiasm among our surgical colleagues, we must begin to use these blocks for surgery, and if the block must be supplemented with local anesthetic or a light general anesthetic, we must educate them that the block is not a failure but a success, as it will provide analgesia after surgery in a method of multimodal pain control. Lower extremity nerve blocks will become more popular when it is realized that they are an effective way of increasing operating room efficiency. Because the block may be placed in an induction room, there is no induction or emergence in the operating room. Patients may be discharged without the need for pain medications, thus lowering the incidence of nausea postoperatively and decreasing PACU and discharge times.

UNLABELLED The three-in-one technique of simultaneously blocking the femoral, the lateral femoral cutaneous (LFC), and the obturator nerves by a single injection of a local anesthetic was first described in 1973, and it was suggested that the underlying mechanism was one of cephalad spread resulting in a blockade of the lumbar plexus. Today, the technique is widely used in surgery and pain management of the lower limb. Many investigators have, however, reported suboptimal analgesia levels, particularly in the obturator nerve. The purpose of this prospective study was to trace the distribution of a local anesthetic during a three-in-one block by means of magnetic resonance imaging (MRI). Seven patients scheduled for surgery of the lower limb were analyzed with the aid of a primary MRI and then received three-in-one blocks using 30 mL of bupivacaine 0.5% under the guidance of a nerve stimulator. A secondary MRI was performed to determine the distribution pattern of the local anesthetic. It emerged that the local anesthetic blocks the femoral nerve directly, the LFC nerve through lateral spread, and the anterior branch of the obturator nerve by slightly spreading in a medial direction. No involvement of the proximal and posterior portions of the obturator nerve was observed, nor was there any cephalad spread that could have resulted in a lumbar plexus blockade. We therefore conclude that the basis of the three-in-one block is confined to lateral, medial, and caudal spread of the local anesthetic, which effectively blocks the femoral and LFC nerves, as well as the distal anterior branch of the obturator nerve. IMPLICATIONS We demonstrate by using magnetic resonance imaging that the mechanism of a three-in-one block is one of lateral, caudal, and slight medial spread of a local anesthetic with subsequent blockade of the femoral, the lateral femoral cutaneous, and the anterior branch of the obturator nerves. It does not involve cephalad spread of the local anesthetic with blockade of the lumbar plexus.

Abstract
Advances in regional anaesthesia to date have made it one of the safest modalities for surgical anaesthesia and pain management. Continued refinement and development of new block techniques and approaches enhance the potential for block success, rapid postoperative recovery and patient safety. This will benefit both patient care and the health care economy.

Abstract
UNLABELLED The use of ultrasound reduces the onset time, improves the quality of sensory block, and minimizes the risks associated with the supraclavicular approach for brachial plexus and stellate ganglion blockade. The present study was designed to evaluate whether ultrasound also facilitates the approach for 3-in-1 blocks. Forty patients (ASA physical status II or III) undergoing hip surgery after trauma were randomly assigned to two groups. In the ultrasound (US) group, 20 mL bupivacaine 0.5% was administered under US guidance, whereas in the control group, the same amount and concentration of local anesthetic was administered with the assistance of a nerve stimulator (NS). After US- or NS-based identification of the femoral nerve, the local anesthetic solution was administered, and the distribution of the local anesthetic solution was visualized and recorded on videotape in the US group. The quality and the onset of the sensory block was assessed by using the pinprick test in the central sensory region of each of the three nerves and compared with the same stimulation on the contralateral leg every 10 min for 60 min. The rating was performed using a scale from 100% (uncompromised sensibility) to 0% (no sensory sensation). Heart rate, noninvasive blood pressure, and oxygen saturation were measured at short intervals for 60 min. The onset of sensory blockade was significantly shorter in Group US compared with Group NS (US 16 +/- 14 min, NS 27 +/- 16 min, P < 0.05). The quality of the sensory block after injection of the local anesthetic was also significantly better in Group US compared with Group NS (US 15% +/- 10% of initial value, NS 27% +/- 14% of initial value, P < 0.05). A good analgesic effect was achieved in 95% of the patients in the US group and in 85% of the patients in the NS group. In the US group, visualization of the cannula tip, the femoral nerve, the major vessels, and the local anesthetic spread was possible in 85% of patients. Incidental arterial puncture (n = 3) was observed only in the NS group. We conclude that an US-guided approach for 3-in-1 block reduces the onset time, improves the quality of the sensory block and minimizes the risks associated with this regional anesthetic technique. IMPLICATIONS The onset time and the quality of a regional anesthetic technique for the lower extremity is improved by ultrasonographic nerve identification compared with older techniques.
