COMFORTABLE AND PROTECTIVE HYBRID WEFT-KNIT PLATED FABRIC FROM GLASS AND WOOL/ACRYLIC YARNS

In this study, hybrid weft-knit plated fabrics were produced by co-feeding glass and wool/acrylic blend yarns. While the wool/acrylic yarn in contact with skin is expected to provide comfort, the glass yarn next to the environment is to provide protection. The physical, structural, air permeability, bursting strength, and the protection against flame properties of glass plus wool/acrylic plated fabric were compared with the reference fabrics consisting completely of glass or wool/acrylic blend yarn. Two factors: the yarn composition and the cam setting of the knitting machine were considered. Two-ply of glass yarn was fed to the each face of the reference glass fabric, and a single-ply of wool/acrylic yarn was fed to the each face of the reference wool/acrylic fabric. On the other hand, while the hybrid plated fabric’s back face accommodated two-ply of glass yarn, its front face involved a single-ply of wool/acrylic yarn. Two different cam settings, loose and tight, were selected. The physical and the structural properties of the fabrics were measured. Then, air permeability, bursting strength, and the protection against flame tests were performed. Test results were subjected to detailed statistical data analysis and how they were affected by the yarn composition and the cam setting was presented with visual and self-explanatory graphs

The Comparison of Postoperative Analgesic Efficacy of Ultrasound-Guided Paravertebral Block and Mid-Point Transverse Process Pleura Block in Mastectomy Surgeries: A Randomized Study

Purpose/Aim of the study The purpose of this triple-blind randomized study is to compare the postoperative analgesic efficacy of Mid-Point Transverse Process Pleura Block (MTP) and Paravertebral Block (PVB) in patients undergoing breast surgery. Materials and Methods The study was retrospectively registered on ClinicalTrials.gov (NCT 05332028). A total of 64 patients undergoing unilateral simple mastectomy operation due to breast cancer were included in the study. Before the anesthesia procedure, participants were randomly assigned to one of two groups: Group 1: Participants undergoing PVB or Group 2: Participants undergoing MTP block. All block applications were performed using 20 mL of 0.25% bupivacaine. Routine general anesthesia protocol was performed on all patients. In the postanesthetic care unit, fentanyl infusion was given to all patients postoperatively via a patient-controlled analgesia device. Postoperative fentanyl consumption, time to the first request for analgesia, VAS score values at rest and in motion, and blocked dermatome areas were recorded. Results Postoperative total opioid consumption, the number of patients given rescue analgesia, the time requiring postoperative supplemental analgesia, postoperative pain scores at rest and in motion, and blocked dermatome areas at both anterior and posterior lower and upper limits were not different between groups (p > 0.05, for all). Conclusions It was concluded that ultrasound-guided PVB and MTP blocks have similar postoperative analgesic efficacy in patients undergoing breast surgery. The MTP block may be preferred as an alternative to PVB for breast surgeries with less risk of complications

Is Infusion of Subhypnotic Propofol as Effective as Dexamethasone in Prevention of Postoperative Nausea and Vomiting Related to Laparoscopic Cholecystectomy? A Randomized Controlled Trial

Background. Postoperative nausea and vomiting (PONV) is one of common complications in patients undergoing laparoscopic cholecystectomy (LC). Aim of this study was to compare the efficacy of subhypnotic (1 mg/kg/h) infusion of propofol with dexamethasone on PONV in patients undergoing LC. Methods. A total of 120 patients were included in this randomized, double-blind, placebo-controlled study. Patients were randomly assigned to 3 groups; patients of group dexamethasone (group D) were administrated 8 mg dexamethasone before induction of anesthesia, patients of group propofol (group P) were infused to subhypnotic (1 mg/kg/h) propofol during operation and patients of group control (group C) were applied infusion of 10% intralipid. The incidence of PONV and needs for rescue analgesic and antiemetic were recorded in the first 24 h postoperatively. Results. In the 0–24 h, the incidence of PONV was significantly lower in the group D and group P compared with the group C (37.5%, 40%, and 72.5%, resp.). There was no significant difference in the incidence of PONV and use of antiemetics and analgesic between group D and group P. Conclusion. We concluded that infusion of propofol 1 mg/kg/h is as effective as dexamethasone for the prevention of PONV during the first 24 hours after anesthesia in patients undergoing LC

Single-dose intravenous ibuprofen versus ultrasound‑guided bilateral superficial cervical plexus block for post‑thyroidectomy pain: A randomized study

Ibuprofen has been using for postoperative pain relief for many years. The bilateral superficial cervical plexus block has been performed for thyroid surgery safely and effectively. We propose to compare them regarding postoperative opioid consumption and pain scores. A total of 60 patients was randomized into two groups. The Ibuprofen group (Group I , n=30) recieved 800 mg intravenous ibuprofen in 100 mL saline 15 minutes before general anesthesia induction. The patients who randomized for bilateral superficial cervical plexus block group (Group S, n=30) were performed a bilateral superficial cervical plexus block group. Opioid consumption, pain scores, and side effects were recorded and data were analysed. The fentanyl consumption during 48 hours after surgery with PCA device was recorded. No significant difference was found. The mean pain scores were recorded at 30 min, 1 h, 2 h, 4 h, 8 h, 12 h, 24 h and 48 h after surgery. No significant difference was found at the first 8 hours between two groups. However, there was statistically significant difference at 12, 24 and 48th hours. No significant difference was found regarding adverse effects in both groups. Both ibuprofen and bilateral superficial cervical plexus block are used for post-thyroidectomy pain in the literature. Ibuprofen has promising effect on postoperative pain relief and opioid consumption. A single dose ibuprofen may prevent pain as successful as bilateral superficial cervical plexus block for 8 hours after surgery. [Med-Science 2019; 8(4.000): 857-60

Spinal anaesthesia at low and moderately high altitudes: a comparison of anaesthetic parameters and hemodynamic changes

Conclusions: Hemodynamic variations and more anaesthetic requirements following the spinal anaesthesia may be observed at moderately high altitudes compared to the sea level
