Kaiyuan Wang, Xiaobei Zhang, Tingting Zhang, Hui Yue, Shan Sun, Hongwei Zhao, Peng Zhou
OBJECTIVES: The pectoral nerves (Pecs) II block is a technique that places local anesthetic between the thoracic muscles to block the axillary and breast regions. This study aimed to compare the quality of perioperative analgesia and side effects of the Pecs II block under general anesthesia versus general anesthesia alone in immediate unilateral breast reconstruction with an implant and latissimus dorsi (LD) flap after modified radical mastectomy. METHODS: Sixty-four patients scheduled for immediate breast reconstruction after modified radical mastectomy were randomly allocated into the Pecs II block under general anesthesia group (Group P, n=32) or the general anesthesia alone group (Group G, n=32)...

Clavicle fractures correspond to 35% of traumatic fractures of the shoulder girdle. Regional anaesthesia has shown better analgesic results than systemic treatment for perioperative management. Innervation of the clavicle is complex, at present its knowledge raises controversy. The lateral pectoral nerve through the innervating musculature predominantly participates in the lateral and anterior part of the clavicle. The following report of 7 cases describes the effective postoperative analgesia of modified PEC II block in patients with middle third clavicle fracture or acromioclavicular dislocation who underwent a modified PEC II block for postoperative pain management, in the context of a multimodal analgesia...

Regional anesthesia for non-obstetric surgery in parturients is a method to decrease patient and fetal risk during general anesthesia. Thoracic interfascial nerve block can be used as an analgesic technique for surgical procedures of the thorax. The Pecs II block is an interfascial block that targets not only the medial and lateral pectoral nerves, but also the lateral cutaneous branch of the intercostal nerve. Pecto-intercostal fascial block (PIFB) targets the anterior cutaneous branch of the intercostal nerve...

Ultrasound-guided Pecs block can provide perioperative analgesia for breast surgery. A single-injection technique (COMBIPECS) combines both Pecs 1 and Pecs 2 blocks in a single needle pass. This technique saves time and is equally effective as the modified Pecs block which uses 2 needle passes. We present a case series of 21 patients who received the COMBIPECS block as a part of multimodal analgesia for breast cancer surgery. The block was administered before the surgery after induction of general anesthesia...

The practice of regional anaesthesia is rapidly changing with the introduction of ultrasound into the working domain of the anaesthesiologist. New techniques are being pioneered. Among the recent techniques, notable are the truncal blocks, for example, the transversus abdominis plane block, rectus sheath block, hernia block and quadratus lumborum block in the abdomen and the pectoral nerves (Pecs) block 1 and 2, serratus anterior plane block and intercostal nerve block. This narrative review covers the brief anatomical discourse along with technical description of the ultrasound-guided truncal blocks...

The recently introduced pectoral nerve (Pecs) block is a simple alterative to the conventional thoracic paravertebral block or epidural block for breast surgery. It produces excellent analgesia and can be used to provide balanced anesthesia and as a rescue block in cases where performing a neuraxial blockade is not possible. In the thoracic region, a neuraxial blockade is often used to manage zoster-associated pain. However, this can be challenging for physicians due to the increased risk of hemodynamic instability in the upper thoracic level, and comorbid and contraindicated medical conditions such as coagulopathy...

BACKGROUND: Pectoral nerve block (PECS block) is first reported by Blanco et al, and mainly used for analgesia for breast surgery in Japan. However, the spread of PECS block is unclear. METHODS: Ultrasound guided PECS I and II blocks were performed in a cadaver, and the cadaver was dissected for evaluation of the spread of coloring matter. RESULTS: The coloring matter by PECS I block was spread to the axillary region between the major and minor pectoral muscles, while PECS II block remained over the fascia of the serratus muscle from mid-clavicular line to middle axillary line...

BACKGROUND: Persistent pain after breast cancer surgery (PPBCS) develops in 15% to 25% of patients, sometimes years after surgery. Approximately 50% of PPBCS patients have neuropathic pain in the breast, which may be due to dysfunction of the pectoral nerves. The Pecs local anesthetic block proposes to block these nerves and has provided pain relief for patients undergoing breast cancer surgery, but has yet to be evaluated in patients with PPBCS. METHODS: The aim of this pilot study was to examine the effects of the Pecs block on summed pain intensity (SPI) and sensory function (through quantitative sensory testing [QST]) in eight patients with PPBCS...

BACKGROUND: The pectoral nerves (Pecs) block types I and II are novel techniques to block the pectoral, intercostobrachial, third to sixth intercostals, and the long thoracic nerves. They may provide good analgesia during and after breast surgery. Our study aimed to compare prospectively the quality of analgesia after modified radical mastectomy surgery using general anesthesia and Pecs blocks versus general anesthesia alone. METHODS: One hundred twenty adult female patients scheduled for elective unilateral modified radical mastectomy under general anesthesia were randomly allocated to receive either general anesthesia plus Pecs block (Pecs group, n = 60) or general anesthesia alone (control group, n = 60)...

A 71-year-old man was scheduled to undergo cardiac resynchronization therapy device (CRTD) implantation. He was combined with severe chronic heart failure due to ischemic heart disease. NYHA class was 3 to 4 and electrocardiogram showed non-sustained ventricular. Ejection fraction was about 20% revealed by transthoracic echocardiogram. He was also on several anticoagulation medications. We planned to implant the device under the greater pectoral muscle. As general anesthesia was considered risky, monitored anesthesia care utilizing peripheral nerve block and slight sedation was scheduled...

OBJECTIVE: The Pecs block (pectoral nerves block) is an easy and reliable superficial block inspired by the infraclavicular block approach and the transversus abdominis plane blocks. Once the pectoralis muscles are located under the clavicle the space between the two muscles is dissected to reach the lateral pectoral and the medial pectoral nerves. The main indications are breast expanders and subpectoral prosthesis where the distension of these muscles is extremely painful. MATERIAL AND METHODS: A second version of the Pecs block is described, called "modified Pecs block" or Pecs block type II...

Fenoterol has been reported to be a potent and selective β(2)-adrenoceptor agonist and is currently used clinically to treat asthma. Electrical field stimulation (EFS) of isolated urinary bladder mimics the voiding contraction by stimulating parasympathetic nerves, resulting in neurogenic contractions. To determine if stimulation of β(2)-adrenoceptors can inhibit this response, fenoterol was tested against EFS-induced contractions in human isolated urinary bladder and compared with mouse and rat. Bladder strips were mounted in organ baths and reproducible contractions induced by EFS...

The aims of the present study were to determine the angiotensin II (AngII) receptor subtype(s) involved in vasoconstriction and enhancement of sympathetic neurotransmission in rat isolated mesenteric arteries. Vasoconstriction was assessed in mesenteric artery ring preparations suspended under 0.5 g of tension in a myograph. In control arteries, with an intact endothelium, AngII (1 nmol/l-3 micromol/l) caused a concentration-dependent contraction. The pEC(50) for AngII was 7.6 +/- 0.2 and the maximum response of 0...

We aimed to study 5-HT(4) receptors in canine stomach contractility both in vivo and in vitro. In anaesthetized Beagle dogs, the selective 5-HT(4) receptor agonist prucalopride (i.v.) induced dose-dependent tonic stomach contractions under isobaric conditions, an effect that was antagonized by the selective 5-HT(4) receptor antagonist GR 125487 (10 microg kg(-1), i.v.). Electrical field stimulation (EFS) of corpus longitudinal muscle strips resulted in atropine- and tetrodotoxin-sensitive contractions (L-NOARG (0...

In the present study, the vasodilator actions of methanandamide and capsaicin in the rat isolated mesenteric arterial bed and small mesenteric arterial segments were investigated. Methanandamide elicited concentration-dependent relaxations of preconstricted mesenteric arterial beds (pEC(50)=6.0+/-0.1, E(max)=87+/-3%) and arterial segments (pEC(50)=6.4+/-0.1, E(max)=93+/-3%). In arterial beds, in vitro capsaicin pre-treatment blocked vasorelaxation to 1 and 3 microM methanandamide, and reduced to 12+/-7% vasorelaxation to 10 microM methanandamide...
