Type or insert the letter, number or symbol that you want to change to superscript. For example, if you want to make an x-squared character, start by using regular letters and numbers -- so type x2 into your document. Take care to highlight only the character you want to format.
Procedures such as laceration repair, which at one time required the use of painful infiltrative anesthetics, can now be accomplished safely and comfortably with the use of topical anesthetics. An additional advantage of topical anesthetics in laceration repair is that wound margins are not distorted.
Sixty-one women with either an episiotomy or a perineal laceration after vaginal delivery were assigned randomly to receive either the application of EMLA cream (n = 31) or infiltration with mepivacaine (n = 30) before perineal suturing. Primary outcome was pain during perineal repair.he findings of this study suggest that a topically applied anesthetic, such as EMLA cream, is more effective in the relief of pain that is experienced during repair of perineal trauma after childbirth than conventional infiltrative anesthesia.
