의약품: 부피바카인

10밀리리터(ml)의 부피바카인 0.50%를 질 열상 부위에 주사합니다.

의약품: 에피네프린

질 열상 부위에 에피네프린(1:200,000)을 주사했습니다.

Time to First Analgesic

The average time to first analgesic (TFA), in minutes, will be evaluated as the duration interval from injection to administration of the first analgesic, as applicable.

Maternal Satisfaction

Maternal satisfaction will be assessed by participants' rating their ability to carry out their daily living activities. Participants will rate their ability to carry out these activities at 24 hours, 48 hours and 7 days using a 5-point scale (1 = very good; 2 = good; 3 = neutral; 4 = poor; or 5 = very poor) such that lower scores are indicative of increased ability to execute daily living activities. No descriptive statistics were completed given the small sample size.

Pain Score After Injection at Perineal Laceration

Participants will self-report measures of symptoms using the Visual Analog Scale (VAS) to determine acute and chronic pain. Participants record a single handwritten mark at one point along the length of a 10-cm line that represents a continuum between the two ends of a scale where "no pain" is on the left end (0 cm) of the scale and the "worst pain" is on the right end of the scale (10 cm). Measurements from the starting point (left end) of the scale to the patients' marks are recorded in centimeters and are interpreted as the intensity of pain. The values will be used to track pain progression for a patient and to compare pain between patients with similar conditions. No descriptive statistics were completed given the small sample size.
