Randomized Controlled Trial[Comparison of ultrasound-guided serratus anterior plane block and erector spinae plane blockperioperatively in radical mastectomy].
Objective: To compare the perioperative effects of ultrasound-guided serratus anterior plane block (SAPB) and erector spinae plane block (ESPB) in radical mastectomy. Methods: One hundred and fifty patients,undergoing radical mastectomy from May 2016 to Jan 2019,the Second Affiliated Hospital and Yuying Children's Hospital of Wenzhou Medical University, were randomly divided into SAPB group, ESPB group and control group. Patients in SAPB group and ESPB group were received corresponding blocks before induction of general anesthesia. ⋯ The incidences of skin itching and nausea in ESPB and SAPB groups were lower than those in control group (P<0.05). There was no difference in the incidence of vomiting among the three groups (P>0.05). Conclusions: Both SAPB and ESPB can provide good and safe analgesia for radical mastectomy,with equivalent performances in analgesia and adverse effect.

The outcome of upper limb tendon transfer surgery is improved when the patient is able to voluntarily contract specific muscles during the surgical procedure. Tumescent local anesthesia is suitable, but we describe an alternative option that involves the novel management of an axillary block. A 47-year-old man, injured in a motor vehicle crash, exhibited a thumb extensor deficit because of severe muscular trauma to the forearm. ⋯ First, individual injections of ropivacaine were performed around the musculocutaneous, radial, and ulnar nerves with ultrasound guidance. Second, a perineural catheter was placed near the median nerve and lidocaine injected. Voluntary flexor muscle contraction reappeared in time for the surgeon to adjust his suture tension.

Bilateral thoracic paravertebral block combined with general anesthesia vs. general anesthesia for patients undergoing off-pump coronary artery bypass grafting: a feasibility study.
Whether thoracic paravertebral block (PVB) is useful in patients undergoing off-pump coronary artery bypass grafting (OPCABG) remains unknown. This study aimed to investigate the feasibility of bilateral PVB combined with general anesthesia (GA) in patients undergoing OPCABG. ⋯ Nerve stimulator-guided bilateral thoracic PVB combined with GA in OPCABG is associated with a reduced rescue analgesia and morphine consumption, compared to GA.

Combined ultrasound and nerve stimulator-guided deep nerve block may decrease the rate of local anesthetics systemic toxicity: a randomized clinical trial.
Ultrasound guidance might decrease the incidence of local anesthetics systemic toxicity (LAST) for many peripheral nerve blocks compared with nerve stimulator guidance. However, it remains uncertain whether ultrasound guidance is superior to nerve stimulator guidance for deep nerve block of the lower extremity. This study was designed to investigate whether deep nerve block with ultrasound guidance would decrease the incidence of LAST compared with that with nerve stimulator guidance, and to identify associated risk factors of LAST. ⋯ Ultrasound guidance, HBV infection and the female sex were risk factors of LAST with LPBs and SNBs. For patients infected with HBV or female patients receiving LPBs and SNBs, we recommended that combined ultrasound and nerve stimulator guidance should be used to improve the safety.
