BACKGROUND This prospective double-blinded, randomized controlled trial compared adductor canal block (ACB) with femoral nerve block (FNB) in patients undergoing total knee arthroplasty. The authors hypothesized that ACB, compared with FNB, would exhibit less quadriceps weakness and demonstrate noninferior pain score and opioid consumption at 6 to 8 h postanesthesia. METHODS Patients received...

Both obturator and sciatic nerve block in combination with femoral nerve block (FNB) have been suggested to be useful in relieving pain after total knee arthroplasty (TKA), compared with FNB alone. We compared their efficacy in this retrospective study. For six consecutive months, patients undergoing unilateral TKA under general anesthesia with continuous FNB plus obturator nerve block (n = 8) ...

Femoral nerve blocks (FNB) can provide effective pain relief but result in quadriceps weakness with increased risk of falls following total knee arthroplasty (TKA). Adductor canal block (ACB) is a relatively new alternative providing pure sensory blockade with minimal effect on quadriceps strength. The meta-analysis was designed to evaluate whether ACB exhibited better outcomes with respect to ...

Background Sciatic and femoral nerve blocks (SNB and FNB) result in effective lower limb analgesia. Classical SNB and FNB require patient repositioning which can cause pain and discomfort. Alternative approaches to sciatic and femoral nerve blocks in supine patients can be useful. Materials and Methods Neurostimulator-guided SNB and FNB from the lateral supratrochanteric approach were perform...

BACKGROUND Femoral nerve blockade (FNB) is a common method of analgesia for postoperative pain control after total knee arthroplasty. We conducted a systematic review to compare the analgesia outcomes in randomized controlled trials that compared FNB (with and without sciatic nerve block) with epidural and patient-controlled analgesia (PCA). METHODS We identified 23 randomized controlled tria...

This study encourages the use of percutaneous FNB to diagnose and stage advanced lung cancer in patients with palpable metastases in supraclavicular lymph nodes or soft tissues. Percutaneous FNB of metastases is much easier to learn than transthoracic needle aspiration: the superficial target is anchored and sampled with multiple passes using a short needle grasped directly in the fingers. It i...

BACKGROUND/AIMS Although the diagnostic accuracy of endoscopic ultrasound with fine needle aspiration (EUS-FNA) in pancreas adenocarcinoma is high, endoscopic ultrasound with fine needle biopsy (EUS-FNB) is often required in other lesions; in these cases, it may be possible to forgo initial EUS-FNA and rapid on-site cytology evaluation (ROSE). The aim of this study was to compare the diagnostic...

BACKGROUND AND STUDY AIMS Techniques to optimize endoscopic ultrasound-guided tissue acquisition (EUS-TA) in a variety of lesion types have not yet been established. The primary aim of this study was to compare the diagnostic yield (DY) of endoscopic ultrasound-guided fine needle aspiration (EUS-FNA) to endoscopic ultrasound-guided fine needle biopsy (EUS-FNB) for pancreatic and non-pancreatic ...

BACKGROUND The quality of liver biopsy specimens obtained with different fine needle biopsy (FNB) techniques has not been compared. OBJECTIVES This study was performed to evaluate the diagnostic quality of three different liver FNB biopsy techniques. MATERIALS AND METHODS Two sequential biopsy series were performed on piglets. Three biopsy techniques were compared: capillary-FNB, core-FNB (...
