Randomized Controlled Trial
Perianal block with ropivacaine as a supplement to anaesthesia in proctological surgery: double-blind randomized placebo-controlled trial (PERCEPT).
The benefit of a perianal block as an adjunct to general or regional anaesthesia is debated. This RCT aimed to compare pain at 24 h and up to 14 days after proctological surgery in patients with and without a perianal block. ⋯ Perianal block as an adjunct to general or regional anaesthesia should be recommended for proctological surgery. It yields a reduction in pain, a reduced need for opioids, and a faster recovery with minimal risk of adverse events. Registration number: NCT03405922 ( http://www.clinicaltrials.gov).

Femoral nerve block (FNB) is a popular technique for reducing postoperative pain in patients with anterior cruciate ligament reconstruction (ACLR), but it is also linked to a number of adverse effects, such as quadriceps weakness, antalgic ambulation, and increased fall risk. Adductor canal block (ACB) has been offered as a motor nerve-sparing alternative to FNB. ⋯ This systematic review suggests that when compared with FNB, ACB preserves quadriceps function in the early postoperative period after ACLR while providing a similar level of analgesia. Limitations of this study include the use of various functional measures and limited long-term follow-up. More research evaluating long-term functional outcomes with standardized measures is needed to draw adequate conclusions regarding the effects of ACB and FNB on function after ACLR.

Randomized Controlled TrialAwake fiberoptic intubation in patients with stenosis of the upper airways: Utility of the laryngeal nerve block.
Awake fiberoptic intubation (AFOI) is mandatory to manage difficult airways. Superior laryngeal nerve block (SLNB) could reduce risks and improve patient comfort. The aim of this study is to assess the procedural comfort of SLNB during AFOI in a population of patients undergoing upper airway oncological surgery. ⋯ Intubation was faster in L-SLNB (47.45 ±15.38 sec) than S-SLNB (80.15 ±37.91 sec) (p <0.001). The SLNB procedure during AFOI is a safe and comfortable procedure in a population of patients undergoing upper airways surgery. Time to intubation was shorter in L-SLNB than in S-SLNB.

Comparison of Adductor Canal Block and Femoral Triangle Block for Total Knee Arthroplasty.
Adductor canal block (ACB) could provide effective postoperative pain control for patients after total knee arthroplasty (TKA). However, some authors pointed out that the ACB as originally described may be more similar to a femoral triangle block (FTB). Recent neuroanatomic evidences made the authors conjecture that the "true" ACB would provide superior analgesia compared with FTB. Therefore, the study was designed to determine the hypothesis that postoperative analgesia after TKA could be improved by a "true" ACB compared with FTB. ⋯ ACB can provide superior analgesia and preserve more quadriceps strength than FTB. ACB facilitates functional recovery in the early stages and is compatible with the highly recognized concept of rapid rehabilitation, which should be promoted in the clinic.

Peripheral Nerve Blocks for Analgesia after Elective Total Hip Arthroplasty.
A significant subgroup of patients suffer from moderate or severe pain after total hip arthroplasty (THA). Regional analgesia has the potential to reduce post-operative pain and thereby spare patients from opioids, but regional analgesia of the hip is complicated as the area is innervated by multiple nerves. ⋯ A femoral nerve block is known to reduce pain after THA, but is unfortunately accompanied by an increased risk of fall. We have developed a novel nerve block-the iliopsoas plane block (IPB)-that has the potential to anaesthetize the hip articular sensory branches of the femoral nerve without causing motor blockade.
