Objectives: Articaine is a rapid-onset, short-duration, local anesthetic. The aim of this study was to study the effect of adding tramadol to articaine in an axillary block to prolong the analgesic effect.
Methods: This study was conducted with 60 patients of American Association of Anesthesiologists classification I or II and aged 18 to 60 years who underwent hand or forearm surgery with an axillary plexus block using a nerve stimulation technique. The patients were randomized into 2 groups: Group A (n=30) received 40 mL 1% articaine and Group AT (n=30) was administered 40 mL 1% articaine with 100 mg tramadol. The onset of sensory block, motor block, duration of sensorial block and motor block, duration of analgesia and hemodynamic parameters were recorded before the block and 5, 10, 20, 30, 60, 120, 180 minutes after the local anesthetic injection.
Results: The sensory block duration in Group AT (187.5±13.0 min) was significantly longer than that of group A (140.78±8.74 min) (p<0.02). The motor block duration in Group AT (137.4±3 min) was significantly longer than that seen in Group A (93.71±9.6 min) (p<0.01). The duration of analgesia was longer in Group AT (218.8±18.2 min) than in Group A (170.8±17.2 min) (p<0.05). In group AT, 2 patients experienced the side effect of nausea and 1 patient had hypotension in the postoperative period.
Conclusion: This study demonstrated that the addition of 100 mg of tramadol to articaine used for an axillary plexus block prolonged analgesia.

Efficacy of Dexamethasone as an Adjuvant for Scalp Nerve Blocks to Prolong Analgesia: A Prospective, Double-Blind, Randomized Controlled Study.

Background: Scalp nerve blocks (SNB) may significantly reduce post-craniotomy pain (PCP) but only for a short period of time. Dexamethasone, as an adjuvant to local anesthetics, was reported to prolong the analgesia duration of never block; however, the addition of dexamethasone to SNB is rare. We therefore tested the hypothesis that dexamethasone as an adjuvant to bupivacaine in SNB is positive after craniotomy.

Study Question: Does the use of slush nitrogen (SN) for embryo vitrification improve embryo transfer outcomes compared to liquid nitrogen (LN)?
Summary Answer: SN is a safe method for embryo preservation and significantly improves post-warming survival rates during repeated vitrification-warming cycles; however, after a single freeze-thaw cycle, pregnancy outcomes are not improved when embryos are vitrified with SN compared to LN.
What Is Known Already: SN is a combination of solid and LN, with a temperature lower than regular LN, and it is an alternative to conventional LN in achieving a faster cooling speed. Studies have shown that SN improves survival in non-human embryos and human oocytes.

Background: For surgical procedures of the upper limbs, ultrasound-guided supraclavicular brachial plexus block (SCBPB) represents a safe substitute for general anesthesia. The present study evaluated the effectiveness and safety of incorporating 1μg/kg dexmedetomidine (DEX) into 20 ml bupivacaine, as opposed to using 20 ml and 30 ml bupivacaine without additives, in SCBPB.
Methods: This randomized, controlled, double-blind study included 75 patients assigned to elective upper-limb surgery under the mid-humerus level.

Introduction: Breast cancer is the most common cancer in females. Surgery is the gold standard therapy, with modified radical mastectomy (MRM) being the most commonly performed procedure for breast cancer. Management of postoperative pain after MRM poses a clinical challenge and hence receives utmost priority.

Introduction: Laparoscopic cholecystectomy has evolved into a daycare procedure thanks to advancements in both surgical and anesthetic techniques. Regional anesthesia, specifically segmental thoracic spinal anesthesia (TSA), offers distinct benefits over general anesthesia, such as enhanced hemodynamic stability and quicker recovery, especially in high-risk patients. This study aims to compare the sensory and motor block characteristics, hemodynamic stability, and incidence of adverse effects between isobaric and hyperbaric 0.
