    ABSTRACT: In this study, we compared pain scores after inguinal herniorrhaphy in patients treated by preincisional local anesthetic field block (PL), or PL combined with perioperative rofecoxib, with controls who received standard care. Seventy-five patients having herniorrhaphy under general anesthesia were randomly assigned to receive a placebo pill preoperatively, and for 5 days postoperatively (CONT); preoperative bupivacaine field block and perioperative placebo (PL); preoperative field block plus rofecoxib, 50 mg preoperatively and for 5 days postoperatively (PLR). Bupivacaine infiltration in the wound at closure, IV fentanyl and acetaminophen/oxycodone were administered postoperatively to all. Discharge time, pain scores (0-10), analgesic use, and satisfaction scores (1-6) were compared using analysis of variance. PLR patients had lower maximum pain scores (worst pain) in the postanesthesia care unit (3.7 versus 5.3, P = 0.02) and at 24 h (5.3 versus 6.8, P = 0.03), were discharged 38 min sooner (P = 0.01), required 28% less oxycodone 0-24 h after discharge (P = 0.04), and reported higher satisfaction scores compared with CONT. Pain in PL was less than CONT for 30 min. There were no differences among the 3 groups after 24 h postoperatively. We conclude that perioperative rofecoxib with PL reduces in-hospital recovery time, decreases pain scores and opioid use, and improves satisfaction scores in the first 24 h after surgery.

    ABSTRACT: We designed this study as a randomized comparison of postoperative pain after inguinal hernia repair in patients treated with triple preincisional analgesic therapy versus standard care. Triple therapy consisted of a nonsteroidal antiinflammatory, a local anesthetic field block, and an N-methyl-D-aspartate inhibitor before incision. The treatment group (n = 17) received rofecoxib, 50 mg PO, a field block with 0.25% bupivacaine/0.5% lidocaine, and ketamine 0.2 mg/kg IV before incision; controls (n = 17) received a placebo PO before surgery. The anesthetic protocol was standardized. Postoperative pain was treated by fentanyl IV and oxycodone 5 mg/acetaminophen 325 mg PO as required for pain. Pain scores (0-10) and analgesic were recorded for the first 7 days after surgery. Pain scores were 47% lower in the treatment group before discharge (3.1 +/- 0.6 versus 5.9 +/- 0.6, P = 0.0026) (mean +/- SE) and 18% less in the first 24 h after discharge (5.6 +/- 0.4 versus 6.8 +/- 0.5, P = 0.05); oral analgesic use was 34% less in the treatment group (4.6 +/- 0.8 doses versus 7.1 +/- 0.7 doses, P = 0.02) in the first 24 h after surgery. We conclude that triple preincisional therapy diminishes pain and analgesic use after outpatient hernia repair, and encourage further evaluation of this technique. IMPLICATIONS: Outpatients undergoing inguinal hernia repair under general anesthesia report moderate-to-severe pain after surgery. Triple preincisional therapy that included rofecoxib, 50 mg PO, ketamine, 0.2 mg/kg IV, and local anesthetic field block reduced pain scores and analgesic use in the first 24 h after discharge.

    ABSTRACT: To compare the onset and offset time (clinical duration), and intubating conditions obtained with rocuronium bromide 0.6 mg/kg and succinylcholine 1.0 mg/kg after induction with propofol and fentanyl; and to compare rocuronium with atracurium for maintenance during propofol anesthesia. Prospective, open-label, parallel group comparative, randomized study. Operating rooms of a university hospital. 30 ASA physical status I and II adult patients scheduled for elective surgeries with general anesthesia. Patients premedicated with midazolam 2 mg were anesthetized with fentanyl 2 microg/kg followed by propofol 2.5 mg/kg and muscle relaxants. Group 1 (n = 15) received succinylcholine 1.5 mg/kg and Group 2 (n = 16) received rocuronium bromide 0.6 mg/kg. Intubation was performed 60 seconds after the administration of muscle relaxant. Patients in Group 1 received atracurium and patients in Group 2 received rocuronium for maintenance if required. The ease of intubation was scored using a scale of 1 to 4. Onset and offset time monitored with evoked twitch response of the adductor pollicis were recorded. Intubation was successful in all patients and there was no difference in scores between the two groups. Although onset time was shorter with succinylcholine than with rocuronium, neuromuscular blockade was successfully antagonized in both groups, and the recovery profile was not different between the two groups. Rocuronium bromide at a dose of 0.6 mg/kg, when used with propofol and fentanyl for induction, provides intubating conditions similar to succinylcholine 1.0 mg/kg at 1 minute. The actual onset time and offset time, however, are significantly longer with rocuronium. There was no difference between atracurium and rocuronium as a maintenance drug. Rocuronium is suitable for surgical procedures greater than 30 minutes, eliminating the need for an additional relaxant to succinylcholine.

    ABSTRACT: This study was designed to test a treatment algorithm for management of bladder function after outpatient general or local anesthesia. Three hundred twenty-four outpatients, stratified into risk categories for urinary retention, were studied. Patients in category 1 were low-risk patients (n = 227) having non-pelvic surgery and randomly assigned to receive 10 ml/kg or 2 ml/kg of intravenous fluid intraoperatively. They were discharged when otherwise ready, without being required to void. Patients in category 2 (n = 40), also presumed to be low risk, had gynecologic surgery. High-risk patients included 31 patients having hernia or anal surgery (category 3), and 31 patients with a history of retention (category 4). Bladder volumes were monitored by ultrasound in those in categories 2-4, and patients were required to void (or be catheterized) before discharge. The incidence of retention and urinary tract symptoms after surgery were determined for all categories. Urinary retention affected 0.5% of category 1 patients and none of category 2 patients. Median time to void after discharge was 75 min (interquartile range 120) in category 1 patients (n = 27) discharged without voiding. Fluids administered did not alter incidence of retention or time to void. Retention occurred in 5% of high-risk patients before discharge and recurred in 25% after discharge. In reliable patients at low risk for retention, voiding before discharge appears unnecessary. In high-risk patients, continued observation until the bladder is emptied is indicated to avoid prolonged overdistention of the bladder.

    ABSTRACT: The goal of this study was to determine whether recovery room monitoring of bladder volume would affect patient outcome after ambulatory surgery. Incidence of urinary retention and times to void and to discharge were compared in 161 patients managed with ultrasound bladder monitoring versus 173 controls without bladder monitoring. Urinary retention was diagnosed by clinical means or by ultrasound, confirmed by bladder catheterization. Patients were required to void or were catheterized before discharge. In the control patients without underlying risk factors for retention, median time to void was 95 min, and retention occurred in 0.8%, which was not significantly different from the ultrasound group (80 min and 0%, respectively). After hernia/anal surgery or spinal/epidural anesthesia, voiding was delayed (130 and 213 min), incidence of retention was increased (17% and 13%), and there was a trend toward earlier voiding (168+/-99 vs. 138+/-68 min) with bladder monitoring. We conclude that most patients at low risk of retention void within 3 h of outpatient surgery; their outcome is unaffected by bladder monitoring. After hernia/anal surgery and spinal/ epidural anesthesia, the likelihood of urinary retention is increased, and ultrasound monitoring facilitates deciding whether such patients should be catheterized. IMPLICATIONS: Incidence of bladder catheterization and urinary retention were compared in patients managed with and without ultrasound monitoring of bladder volume after outpatient surgery. Monitoring did not alter outcome in patients at low risk of retention, but it facilitated determining when to catheterize patients at high risk of retention (hernia/anal surgery, spinal/epidural anesthesia).

    ABSTRACT: This experiment was undertaken for three purposes: (1) to determine a dose-response curve of acute steroid inhibition of wound contraction in the rat; (2) to confirm the results of our preliminary study that platelet-derived growth factor (PDGF) enhanced wound contraction in acutely steroid impaired rats; and (3) to examine the histology of the PDGF-treated wounds. To determine the dose-response of acute steroid inhibition of wound contraction, the rats were suppressed with daily doses of methylprednisolone and wound contraction was measured. Results demonstrated that significant glucocorticoid-induced inhibition of wound contraction begins with daily methylprednisolone doses of 2.0 mg/wound/day or 6.7 mg/kg/day. In an effort to confirm the results of our previous study of the effect of PDGF on wound contraction in acutely steroid-impaired rats and to study the histology of the PDGF-treated wounds, rats were suppressed with methylprednisolone or hydrocortisone and administered daily topical doses of rPDGF-BB. Wound contraction measurements revealed no improvement in the amount or rate of wound contraction. Histologically, the wounds were all very similar in the patterns of cellularity, granulation tissue maturity, collagen content, and epithelial migration. We have clarified the dose response of acute steroid inhibition of wound contraction in rats, data previously unavailable, and have concluded that PDGF in reasonable doses does not improve wound contraction in steroid-impaired rats nor does it alter the histology of the wounds.

    ABSTRACT: Using an illustrative case of severe closed head injury that resulted in a posterior fossa epidural hematoma (EDH) and supratentorial epidural/subdural hematomas (SDH), the massive blood losses associated with operative repair of the torn sigmoid sinus and the significant fluid losses associated with refractory diabetes insipidus were treated by the intraoperative use of the Rapid Infusion System (RIS, Haemonetics). The RIS can rapidly infuse warm blood, crystalloid, or colloid at rates up to 1.5 L/min, thereby limiting the commonly associated hypotension, hypothermia, and coagulopathies. During the suboccipital craniectomy for evacuation of the EDH and repair of the sigmoid sinus, the patient required 18 units of blood replacement secondary to a large tear in the sigmoid sinus. During a separate craniotomy for evacuation of the SDH, the patient also developed diabetes insipidus, which increased the operative fluid replacement to 39 L. Despite these massive blood and fluid losses, the RIS limited the hypotension to less than 2 min and prevented hypothermia and the frequently associated coagulopathies. When used in a neurosurgical setting associated with massive blood and/or fluid losses, the RIS accomplishes three important objectives: (1) rapid infusion of intravenous fluids for maintaining perfusion pressure, (2) rapid warming of fluids despite high intravenous infusion rates of cold crystalloids, thereby preventing intraoperative hypothermia, and (3) continuous monitoring of infusion rates and totals.

    ABSTRACT: Nine cases of traumatic aortic tear treated during 1986-1987 were reviewed. Two patients had functioning Gott shunts, six patients had simple crossclamp, and one patient had a Gott shunt placed which was nonfunctional. Anesthetic management was similar in all patients. Clamp times ranged in unshunted patients from 25 to 38 minutes, and in shunted patients from 42 to 50 minutes. The crossclamp time of the patient with the nonfunctional shunt was 42 minutes. Declamping was accompanied in unshunted patients by decreases in core temperature of up to 1 degree C and acute decreases in PaO2. Marked respiratory and metabolic acidosis occurred with declamping. Respiratory acidosis resolved within 30 minutes with hyperventilation, but metabolic acidosis persisted despite bicarbonate therapy (mean = 1.2 mEq/kg) up to 6 hours after declamping. Associated elevations in serum potassium resolved as pH returned to baseline. Acid-base and electrolyte abnormalities were less marked in patients who were shunted.
