Background: In our experience, for all surgeries in the hand, the optimal epinephrine effect from local anesthesia-producing maximal vasoconstriction and visualization-is achieved by waiting significantly longer than the traditionally quoted 7 min from the time of injection. Methods: In this prospective comparative study, healthy patients underg...

The randomized controlled trial is a reliable study design for assessing the effectiveness of a surgical intervention, provided it is adequately powered. This systematic review examines the appropriateness of reporting of power and sample size in randomized controlled trials within the plastic surgery literature. Original randomized controlled tria...

... Keep in mind that, in cases done with pure WALANT, it takes about 30 minutes after administration for the chemical tourniquet effect of epinephrine to be optimal. 19 In the authors' clinic workflow (Fig. 2), surgeries are scheduled at the beginning or end of a clinic day. An alternative model is to schedule surgery-only days. ...
... By adding epinephrine to the local anesthesia, a vasoconstrictive effect is created, which causes minor blood loss during surgery. 5 Several studies have been conducted on the effects of tourniquet use on perioperative pain. [6][7][8][9][10] A systematic review by Evangelista et al 2 examined whether there was a difference in WALANT technique versus regional and local anesthesia with tourniquet concerning perioperative and short-term outcomes. ...
... Sex was categorized into female and male groups, among which, 100 were males (55%) and 83 were females (45%). Too small sample sizes could reduce the power of the study and increase the probability of error, which can render the study meaningless (Ayeni et al., 2012). Thus, statistical power analysis was performed for estimating sufficient sample sizes to achieve adequate power (Billoir et al., 2015;Blaise et al., 2016). ...
... Tumor surgery and radiotherapy may lead to multiple injuries with craniocerebral trauma or partial scalp necrosis. It has been reported widely on various methods of repairing scalp avulsion/defect, including anastomotic vessels for total scalp avulsion, and dermal grafts (skin grafting, latissimus dorsi or anterior serratus flap, "visor flap" repair, etc.) [1][2][3][4][5][6]. However, the long-term retrospective study with large sample size remains rare; and there is no report on decision-making tree for repairing emergency scalp avulsion/defects under critical conditions. ...
