PEC II Block

Boohwi Hong, Seok-Hwa Yoon, Ann Misun Youn, Bum June Kim, Seunghyun Song, Yeomyung Yoon
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...

A 22-years-old female patient at 171 cm and 67 kg visited the Department of Breast Surgery of the hospital with a mass accompanied with pain on the left side breast as chief complaints. Since physical examination revealed a suspected huge mass, breast surgeon decided to perform surgical excision and requested anesthesia to our department. Surgery of breast tumor is often under local anesthesia. However, in case of big size tumor, surgery is usually performed under general anesthesia. The patient feared general anesthesia...

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: 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)...

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...

BACKGROUND/AIM: Both superior parietal lobule (SPL) of dorsolateral hemispheric surface and precuneus (PEC) of medial surface are the parts of posterior parietal cortex. The aim of this study was to determine the numerical density (Nv) of pyramidal neurons in the layer V of SPL and PEC and their potential differences. METHODS: From 20 (40 hemispheres) formaline fixed human brains (both sexes; 27- 65 years) tissue blocks from SPL and PEC from the left and right hemisphere were used...

BACKGROUND: The susceptibility of porcine endothelial cells (pEC) to human natural killer (NK) cells is related to the failure of human major histocompatibility complex (MHC)-specific killer inhibitory receptors to recognize porcine MHC class I molecules. The aims of this study were (i) to assess the protection of pEC against xenogeneic NK-mediated cytotoxicity afforded by the stable expression of HLA-E single chain trimers (SCT) composed of a canonical HLA-E binding peptide antigen, VMAPRTLIL, the mature human beta2-microglobulin, and the mature HLA-E heavy chain, and (ii) to test whether HLA-E expression on pEC and porcine lymphoblastoid cells affects the adhesion of human NK cells...

BACKGROUND: Thy-1.1 transgenic mice develop hypercellular focal and segmental glomerulosclerosis (FSGS) lesions that mimic human collapsing FSGS, in 7 days after injection with anti-Thy-1.1 antibodies. These lesions consist of proliferating parietal epithelial cells (PECs). We questioned whether the angiotensin converting enzyme inhibitor (ACE), captopril, could prevent the development of FSGS and if protection is related to the timing of drug administration. METHODS: First, we compared the effect of captopril treatment with angiotensin II-(ANGII) independent antihypertensive therapy (triple therapy)...

BACKGROUND: Angiotensin II (Ang II) is a potent vasoconstrictor and a deleterious factor in cardiovascular pathophysiology. Ang II receptor blockers (ARBs) have recently been introduced into clinical practice for treatment of hypertension and congestive heart failure. AIMS: This study was undertaken to evaluate the inhibitory effects of ARBs on vasoconstriction in humans. METHODS: Vasomotor tone was analyzed in endothelium denuded, human coronary artery (HCA) segments...

1. Human urotensin-II (hU-II), a cyclic undecapeptide, is amongst the most potent mammalian vasoconstrictors identified, suggesting that hU-II and its G-protein-coupled receptor (UT) may regulate cardiovascular homeostasis. Such a hypothesis would benefit greatly from the development of selective UT antagonists. 2. Although the somatostatin (SST) antagonist SB-710411 (Cpa-c[D-Cys-Pal-D-Trp-Lys-Val-Cys]-Cpa-amide) is purported to block U-II-induced contractions in rat isolated aorta, little is known about its specific pharmacological properties...

Urotensin II is a cyclic undecapeptide which activates the GPR14 receptor and exerts potent vasoconstrictor effects in some species of fish and mammals. The present study intended to investigate isolated vessels from various species in an attempt to find sensitive preparations to be used in studies of the human urotensin (hU-II)/GPR14 system. Contractile responses evoked by noradrenaline (NA), angiotensin II (Ang II), endothelin 1 (ET-1) and hU-II were measured in large vessels (aorta and some large arteries and veins) of rats, guinea pigs, rabbits, pigs and humans...

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...

ACE inhibitors block B(2) receptor desensitization, thereby potentiating bradykinin beyond blocking its hydrolysis. Angiotensin (Ang)-(1-7) also acts as an ACE inhibitor and, in addition, may stimulate bradykinin release via angiotensin II type 2 receptors. In this study we compared the bradykinin-potentiating effects of Ang-(1-7), quinaprilat, and captopril. Porcine coronary arteries, obtained from 32 pigs, were mounted in organ baths, preconstricted with prostaglandin F(2alpha), and exposed to quinaprilat, captopril, Ang-(1-7), and/or bradykinin...

1. The contribution of endothelin-1 (ET-1) to angiotensin II (Ang II)-mediated contraction of the isolated rat tail artery was assessed with measurements of tension, and cytosolic calcium ([Ca(2+)](i)). The distribution of the AT(1) receptor was studied with RT - PCR and immunohistochemistry. 2. Ang II induced an endothelium-independent contraction (pEC(50) 7.95+/-0.06 and E(max): 0.46 g+/-0.05 with endothelium vs 7.81+/-0.02 and 0.41 g+/-0.07 without endothelium; P>0.05). Ang II (0.003 - 0.3 microM)-induced a non-sustained contraction of endothelium-intact preparations which was not antagonized by BQ-123 (1 microM), but was inhibited by losartan (10 nM)...

T cells primed specifically for the envelope glycoprotein of Friend murine leukemia helper virus (F-MuLV) were prepared by immunizing mice with a recombinant vaccinia virus that expressed the entire env gene of F-MuLV. Significant proliferative responses of F-MuLV envelope-specific, H-2a/b T cells were observed when the T cells were stimulated with antigen-pulsed peritoneal exudate cells (PEC) having the b allele at the K, A beta, A alpha, and E beta loci of the H-2. On the other hand, PEC having only the kappa allele at these loci did not induce the envelope-specific T cell proliferation, even when the PEC had the b allele at the E alpha, S, or D loci...

MRL-lpr mice and their congenic counterparts MRL-+ spontaneously develop an autoimmune disease that resembles systemic lupus erythematosus in humans. The two strains, although congenic, differ by a considerable number of disease parameters, reflecting the expression of the lpr autosomal recessive gene. One paradox that has developed out of the work utilizing the congenic mice is that the gene responsible for lymphoproliferation also appears to be responsible for the inability of T cells to respond to proliferative signals in vitro...

Guinea pig proliferating T cell colonies were isolated from T cell populations stimulated during the syngeneic mixed leukocyte reaction (SMLR) or following positive selection of immune T lymphocytes specific for pork insulin (PI) or the copolymer of L-glutamic acid, L-lysine (GL). SMLR-responding T cell colonies could be isolated in the absence of any extrinsic antigen and were strictly restricted to the recognition of Ia molecules on stimulator peritoneal exudate cells (PEC) and required both stimulator cells and interleukin 2-enriched fluids for optimal proliferative responses...
