The continuous infusion fascia iliaca compartment block: a safe and effective analgesic modality in geriatric hip fracture patients.

OBJECTIVE: Hip fractures are common orthopaedic injuries in the elderly. Opioids can provide peri-operative pain relief in hip fracture patients, but may have side effects. Peripheral nerve blocks such as the fascia iliaca compartment block (FICB) have become an established part of the multimodal analgesic regime administered peri-operatively to hip fracture patients. We compare the efficacy of the continuous infusion FICB (CFICB) on peri-operative pain relief, opioid usage, its associated complications and the short as well as long term rehabilitation status in geriatric hip fractures patients. MATERIALS AND METHODS: In this retrospective matched case control study, 40 geriatric patients with hip fractures who had received the CFICB from Nov 2014 to April 2016 were matched in a 1:3 ratio with similar patients whom had not received the CFICB from our institution's hip fracture database of 913 patients. RESULTS: A total of 157 patients in both the CFICB group (N = 40) and the control group (N = 117) were studied. The post-operative pain scores and the total opioid consumption during the first 3 days in the CFICB group were significantly less than the control group (p < 0.0001, respectively). The systemic complications in the CFICB group were comparable with the control group. The CFICB group had slower rehabilitation at up to 2 weeks but there was no significant difference at 1 year post surgery in terms of function and mobility between the two groups. In both groups, better pre-fracture function was associated with faster short term rehab outcomes in post-operative patients. CONCLUSION: The CFICB provides safe and effective post-operative pain relief in geriatric hip fracture patients. Post-operative opioid usage is decreased in older hip fracture patients treated with CFICB. Rehabilitation milestones are slower in the short term, but have no significant difference at 1-year post surgery.

Management plan to reduce risks in perioperative care of patients with obstructive sleep apnoea averts the need for presurgical polysomnography.

INTRODUCTION: Obstructive sleep apnoea (OSA) is associated with increased perioperative morbidity and mortality. Patients at risk of OSA as determined by pre-anaesthesia screening based on the American Society of Anesthesiologists checklist were divided into 2 groups for comparison: (i) those who proceeded to elective surgery under a risk management protocol without undergoing formal polysomnography preoperatively and; (ii) those who underwent polysomnography and any subsequent OSA treatment as required before elective surgery. We hypothesised that it is clinically safe and acceptable for patients identified on screening as OSA at-risk to proceed for elective surgery without delay for polysomnography, with no increase in postoperative complications if managed on a perioperative risk reduction protocol. MATERIALS AND METHODS: A retrospective review of patients presenting to the preanaesthesia clinic over an 18-month period and identified to be OSA at-risk on screening checklist was conducted (n = 463). The incidence of postoperative complications for each category of OSA severity (mild-moderate and severe) in the 2 study groups was compared. RESULTS: There was no statistically significant difference in the incidence of cardiac (3.3% vs 2.3%), respiratory (14.3% vs 12.5%), and neurologic complications (0.6% vs 0%) between the screening-only and polysomnography-confirmed OSA groups respectively (P >0.05). There was good agreement of the OSA risk that is identified by screening checklist with OSA severity as determined on formal polysomnography (kappa coefficient = 0.953). CONCLUSION: Previously undiagnosed OSA is common in the presurgical population. In our study, there was no significant increase in postoperative complications in patients managed on the OSA risk management protocol. With this protocol, it is clinically safe to proceed with elective surgery without delay for formal polysomnography confirmation.

Postoperative pain control for total knee arthroplasty: continuous femoral nerve block versus intravenous patient controlled analgesia.

BACKGROUND: Pain after total knee arthroplasty is severe and impacts functional recovery. OBJECTIVES: We performed a retrospective study, comparing conventional patient control analgesia (PCA) modalities versus continuous femoral nerve blockade (CFNB) for 1582 post-TKA (total knee arthroplasty) patients. PATIENTS AND METHODS: Using our electronic acute pain service (APS) database, we reviewed the data of 579 patients who had received CFNBs compared with 1003 patients with intravenous PCA over 4 years. RESULTS: Our results show that the incidence of a severe pain episode was higher in the PCA compared with the CFNB group. Lower pain scores were observed in the CFNB group compared with the PCA group from postoperative day (POD) 1 to 3, primarily due to lower rest pain scores in the CFNB group. CONCLUSIONS: Our study shows that there is improvement in pain scores, at rest and on movement, as well as a reduction in incidence of severe pain, in patients who receive CFNB versus those who receive intravenous PCA.
