ABSTRACT
Background: Femur fractures are extremely painful due to the lowest pain threshold of the periosteum among the deep somatic structures. Perioperative Fascia Iliaca Compartment Block (FICB), when administered using a local anesthetic agent, bupivacaine, can reduce morbidity by providing satisfactory pain relief. Dexmedetomidine, an alpha-2 agonist, is known to prolong the local anesthetic effects without causing any significant side effects. We compared analgesic duration of ultrasound guided FICB with bupivacaine alone and bupivacaine with dexmedetomidine for postoperative analgesia. A prospective, randomized, double blinded study was conducted on 50 patientsMaterials And Method: aged 18 to 65 years undergoing femur fracture surgeries. Patients were divided into 2 groups of 25 each. Both groups received USG guided FICB. Group A received 28 ml 0.25% bupivacaine and 2 ml normal saline (NS). Group B received 28 ml 0.25% bupivacaine and 30 mcg dexmedetomidine in NS. Pain scores were assessed every 5 minutes until 15 minutes post FICB, during positioning for subarachnoid block and every 2 hours until 24 hours post-operatively. Total duration of analgesia, cumulative analgesia requested in 24 hours, Ramsay sedation and patient satisfaction scores were recorded. Results: The mean duration of analgesia in Group A was 419.4 ± 115.35 minutes (95%CI: 374.2 – 464.6) and in Group B was 656.6 ± 137.99 minutes (95%CI: 602.5 –710.7), p <0.001. Mean VAS score during positioning for SAB in Group A was 1.60 ± 0.50 and in Group B was 0.96 ± 0.68. USG guided FICB with dexmedetomidine is superior inConclusion: providing prolonged post-operative analgesia in comparison to bupivacaine alone
ABSTRACT
Objective:To compare the analgesic effect and postoperative recovery between multi-point and single-point ultrasound-guided fascia iliaca compartment block (FCIB) in elderly patients with hip fracture.Methods:From June 2019 to April 2020, 96 patients aged (71.1±5.4) years undergoing elective surgery for hip fracture in Renji Hospital were randomly assigned in multi-point block group or single-point block group, and the multi-point or single-point ultrasound-guided FCIB was performed for the two groups, respectively. The primary outcomes were the success rate for block of femoral nerve, lateral femoral cutaneous nerve and obturator nerve, and the 24 hours postoperative pain visual analog scale (VAS) score at rest and passive movement. The secondary outcomes were the onset time of sensory blocks of the above three nerves, complications of FICB, the satisfaction score of pain control during 48 hours after surgery and postoperative recovery of patients.Results:The success rate for block of lateral femoral cutaneous nerve in multi-point block group was 97.9% (47/48), which was significantly higher than that in single-point block group (83.3%(40/48)) ( P=0.031). The success rate for block of obturator nerve in multi-point block group was 95.8% (46/48), which was significantly higher than that in single-point block group which was 81.3% (39/48) ( P=0.025). The success rate of femoral nerve block in both groups was 97.9% (47/48) ( P=1.000). The 24 hours postoperative VAS scores at rest and passive movement in the multi-point block group were significantly lower than those in the single-point block group ( P<0.05). The onset time for block of lateral femoral cutaneous nerve and obturator nerve in multi-point block group was shorter than that in single-point block group ( P=0.025 and P<0.01). There was no significant difference in the onset time for block of femoral nerve between the two groups ( P=0.343). The satisfaction score of patients at 48 hours after surgery in multipoint block group was higher than that in single point block group ( P=0.024). The length of hospital stay in the multi-point block group was shorter than that in the single-point block group ( P=0.042), the proportion of intravenous analgesic drugs used after surgery was lower than that in the single-point block group ( P=0.041), and the complication rate within 30 days after surgery was also lower than that in the single point block group ( P=0.026). Conclusion:Compared with single-point block, ultrasound-guided multi-point block in iliac fascia space has advantages of increasing analgesic efficacy and promoting postoperative recovery in elderly patients with hip fracture.
ABSTRACT
Objective:To identify the effective concentrations of Ropivacaine in the modified fascial iliac compartment block(FICB)that would not affect the movement of the affected limb but would offer effective pain relief after total knee arthroplasty(TKA)in elderly patients.In addition, adverse reactions within 24 hours of FICB were examined.Methods:This study was a prospective, single-arm sequential trial.Forty-five elderly patients treated with TKA at the First Affiliated Hospital of Soochow University between September 2021 and March 2022 were selected, with an American Society of Anesthesiologists(ASA)score of Ⅰ or Ⅱ.All patients were given ultrasound-guided FICB on the surgical side under general anesthesia and 10 minutes before the operation, and the injection volume was 30 ml.According to preliminary experiments and relevant literature, the initial concentration of Ropivacaine was 0.1%, and the concentration for the next patient was determined using a modified Dixon sequential method.If the quadriceps femoris muscle strength score of the first patient was ≥4, there was no resting pain[visual analogue scale(VAS)score ≤1], and the VAS score during activity was ≤3, the concentration for the next patient would be reduced.Conversely, the concentration would be increased.The Ropivacaine concentration was increased or decreased by 0.01% each time and the trial would be stopped after 12 reentries.The median effective concentration(ED50), 95% effective concentration(ED95)and corresponding 95% confidence interval(CI)of ropivacaine were calculated using the probit model.Meanwhile, adverse reactions within 24 hours of FICB were monitored.Results:Of 43 elderly patients who completed the trial, the intervention was effective in 23 and ineffective in 20.While ensuring that postoperative limb movement in elderly patients was not affected, a single injection of 30 ml ropivacaine through FICB was able to effectively inhibit postoperative pain, and the ED50 and ED95 of ropivacaine were 0.072%(95% CI: 0.065%-0.078%)and 0.093%(95% CI: 0.084%-0.124%), respectively.Within 24 hours of FICB, 2 patients had lower limb weakness and could not get out of bed and walk, and 5 patients had severe pain and needed additional analgesics.No other adverse reactions were found. Conclusions:The effective ED50 and ED95 of Ropivacaine for postoperative pain relief in elderly patients after TKA are 0.072% and 0.093%, respectively.And the incidence of adverse reactions is low.

Background: Fascia iliaca compartment nerve block (FICB) is commonly preferred pain management technique in femoral fractures. Dexamethasone and clonidine as adjuvants to local anesthetics have good analgesic effect with limited adverse effect. Aim and Objectives: To assess the efficacy of bupivacaine with clonidine, bupivacaine with dexamethasone, and bupivacaine alone in fascia iliaca compartment block in cases with femoral fractures. Materials and Methods: The present prospective randomized study included a total of 120 cases undergoing proximal femoral surgeries under subarachnoid block above 21 years. The study cases were randomly divided into three study groups, i.e. 40 participants in each group. Group 1 received 0.25% bupivacaine with 2 ml normal saline, Group 2 received 0.25% bupivacaine with 50mcg clonidine, and Group 3 received with 0.25% bupivacaine with 8mg dexamethasone. Parameters such as heart rate (HR), mean arterial pressure (MAP), systolic blood pressure (SBP), diastolic blood pressure (DBP), oxygen saturation levels, and visual analog scale (VAS) score was monitored and recorded. Results: The mean difference of HR between the study groups was statistically not significant (P > 0.005). The mean SBP, DBP, and VAS score was comparable between study groups. The mean analgesic duration in Group 1 was 6.01 h, in Group 2 was 13.58 h, and in Group 3 was 14.44 h. The mean difference of rescue analgesia requirement and duration of rescue analgesia was statistically significant. No adverse effects toward drugs were noticed. Conclusion: About 0.25% bupivacaine with 8 mg Dexamethasone had better analgesic duration and require minimal rescue analgesia in the first postoperative day than 0.25% bupivacaine with 50 mcg clonidine in cases undergoing femoral surgeries under FICB.
ABSTRACT
Background: Comparison of ropivacaine alone or with dexamethasone as an adjuvant for reducing pain during positioning for neuraxial blockade with ultrasound-guided fascia iliaca compartment block.Methods: In this double-blinded study, a total of 60 patients between 18 to 80 years of age, undergoing surgery for hip fracture were enrolled. Patients in Group A received 40 ml of 0.25% ropivacaine +2 ml saline and patients in Group B received 40 ml of 0.25% ropivacaine +8 mg dexamethasone. USG guided FICB and postoperative monitoring was done by the chief investigator who was unaware of group allotted and drug administered.Results: There is no significant difference in the heart rate between the two groups after 30 min of the block. The variation of systolic blood pressure of both the group for the first 30 min after giving FICB block was not significant (p>0.05). The absolute value of diastolic blood pressure (DBP) was significantly lower in Group B compared to group A just before the block, a variation of DBP with time was not significant. There was a gradual improvement of pain score from mean 6.7 in Group A and 6.6 in Group B at 0 min to score of 2 at the end of 30 min in both the group. This improvement was achieved earlier in Group B compared to Group A, although the difference was not significant (p>0.05). Vital parameters like HR, SBP, DBP, SpO2 values were similar in both the groups. No patients in either group required any interventions both pre-operatively and pos-operatively. Time of rescue analgesia was noted with the VAS score was significantly more in Group B (p≤0.004). The incidence of hematoma, accidental intravascular injection, convulsion, and paresthesia were nil in both groups.Conclusions: Although both the groups had comfortable and pain-free positioning for administering spinal anaesthesia before surgery. USG guided FICB is easy to perform block and give excellent analgesia for positioning and mobilization of hip fracture patients pre and post-operatively both, and dexamethasone as an adjuvant to 0.25%ropivavaine prolong its local anesthetic effect significantly.
ABSTRACT
Objective@#To compare the efficacy of ultrasound-guided fascia iliaca compartment block(FICB) above inguinal ligament and longitudinal inguinal FICB for postoperative analgesia in elderly patients undergoing total hip arthroplasty (THA).@*Methods@#Sixty American Society of Anesthesiologists physical statusⅠ orⅡ patients of both sexes, aged 65-76 yr, with body mass index of 19-26 kg/m2, scheduled for elective unilateral THA, were divided into 2 groups (n=30 each) using a random number table method: FICB above inguinal ligament group (S group) or longitudinal inguinal FICB group (G group). After the end of surgery, patients received ultrasound-guided FICB using a short-axis in-plane technique in S group and longitudinal inguinal FICB using a long-axis in-plane technique in G group, and patients received 0.4% ropivacaine as a loading dose of 40 ml, followed by continuous infusion of 0.2% ropivacaine 5 ml/h for 48 h. Ultrasound imaging time, puncture injection time and operating time of FICB were recorded.The efficacy of nerve block, effective pressing times, cumulative consumption of ropivacaine, satisfaction with analgesia, and development of related complications were recorded at 6, 12, 24, 36, 48 and 72 h after surgery (T1-6).@*Results@#Compared with group G, the requirement for rescue analgesia with dezocine was significantly decreased, the effective pressing times at T3-5 and cumulative consumption of ropivacaine at T3, 4 were reduced, and the success rate of obturator nerve block was increased at T1-6 in group S (P<0.05). There were no significant differences in the success rate of the femoral nerve and lateral femoral cutaneous nerve block, satisfaction with analgesia and development of related complications between the two groups (P>0.05).@*Conclusion@#Ultrasound-guided FICB above inguinal ligament increases the success rate of the obturator nerve block, provides better efficacy for postoperative analgesia and is more helpful for early postoperative functional exercise and recovery than the longitudinal inguinal FICB in the patients undergoing THA.

ABSTRACT
Objective To observe the analgesia efficacy of continuous fascia iliaca compartment block (FICB) and adductor canal block (ACB) on elderly patients undergoing total knee arthroplasty (TKA) with multimodal analgesia and their early rehabilitation. Methods Sixty TKA patients (26 female and 34 male, 60-75 years old) were randomly divided into two groups and received ultrasound-guided either continuous FICB (n=30) or continuous ACB (n=30) using 0.25% ropivacaine for controlled analgesia. All the patients had no previous experiences of knee surgery. Quality of analgesia was assessed by dynamic and static visual analogue scale (VAS) based on pain intensity. In addition, rehabilitation training compliance, range of motion (ROM) and knee function were assessed at different times after rehabilitation training. Results No significant differences were found in VAS scores during resting and passive functional exercise at 6, 12, 24, 48 h after TKA surgery (P>0.05); ACB group had significant differences in rehabilitation training compliance, knee ROM and HSS scores in comparison with FICB group (P<0.05). Conclusions Ultrasound-guided continuous ACB with multimodal analgesia could promote early rehabilitation after TKA．
