The general recommended strategy after arterial invasive procedures is a 4- to 6-hour bed rest that is associated with patient discomfort and increased medical costs. We hypothesized that mobilization of selected patients at the second hour would not increase vascular complications. Coronary angiography was performed through the femoral route via 6-Fr catheters. Homeostasis was achieved by manual compression and maintained with a compressive bandage. A total of 1,446 patients were ambulated at the second hour and 1,226 of them were discharged without complication. A total of 220 patients required further follow-up due to blood oozing; 154 patients were conventionally ambulated due to difficult arterial access, longer (>15 minutes) compression time, hematoma formation within 2 hours, or hypertensive state (blood pressure >180/100 mm Hg). Twenty-five (16%) of those patients developed minor bleeding after ambulation. No major bleeding or large hematoma was observed during in-hospital observation. Ecchymosis (10% [2-hour group] vs 21% [4-5 hour group]) and small hematomas (22% vs 9%) were the most frequent complications after discharge. Early mobilization of selected patients undergoing diagnostic heart catheterization through the femoral artery via 6-Fr catheters is safe and associated with acceptable bleeding complication rates.

Background: In this prospective, randomized, double-blind, controlled study, we investigated the sensory, motor and analgesic block characteristics of S(+) ketamine, fentanyl and saline given intrathecally (IT) in addition to 0.5% plain bupivacaine (10 mg) for spinal analgesia. Methods: Ninety ASA I or II adult patients undergoing Caesarean section were randomly allocated to receive 1.0 mL of 0.9% saline in Group S (n = 30), 0.05 mg kg-1 of S(+) ketamine (1.0 mL) in Group K (n=30) or 25 μg (1.0 mL) of fentanyl in Group F (n=30) following 10 mg of plain bupivacaine 0.5% IT. We recorded onset and duration of sensory and motor block, time to reach the maximal dermatomal level of sensory block and duration of spinal analgesia. Results: The onset time of sensory and motor block was significantly shorter in Groups K and F than in Group S (P < 0.014). Their duration was significantly longer in Group F than in Groups K and S (P < 0.009). The time to reach the maximal dermatomal level of sensory block was significantly shorter in Groups K and F than in Group S (P < 0.001). The duration of spinal analgesia was significantly longer in Group F than in Groups K and S (P < 0.001). Conclusion: In patients undergoing Caesarean section with spinal analgesia, the addition of S(+) ketamine (0.05 mg kg -1) IT to 10 mg of spinal plain bupivacaine (0.5%) led to rapid onset of both sensory and motor blockade and enhanced the segmental spread of spinal block without prolonging the duration of spinal analgesia, whereas fentanyl provided prolonged analgesia [ABSTRACT FROM AUTHOR]

Background and objective; To compare the antiemetic efficacy of ondansetron with two different hypnotic drugs (propofol 15 mg, midazolam 1 and 2 mg) for the treatment of established postoperative nausea and vomiting (PONV). Methods: Four-hundred-and-fifty-three patients scheduled for elective gynaecological or abdominal surgery were enrolled. One-hundred-and-twenty patients (26%) experienced postoperative emesis, and when nausea sczepinsores reached 2 or greater on a five-point scale, they were randomized to receive intravenously: propofol 15 mg (1.5 mL) in Group P, midazolam 1 mg in Group M l, midazolam 2 mg in Group M2 and ondansetron 4 mg in Group O. Results: Four patients (13.3%) in Group P, 13 patients (43.3%) in Group Ml, five patients (16.6%) in Group M2 and one patient (3.3%) in Group O required a second dose of the study drug. After administration of the study drugs, nausea scores were significantly lower in all groups than before these drugs were given. No patient had a sedation score over 3 (the patients remained awake and/or responded to verbal contact). The sedative effects of midazolam and proposal lasted tor a much shorter time than the antiemetic effects of these drugs, Conclusions: Propofol and midazolam used in subhypnotic doses were as effective as ondansetron in treating PONV in patients undergoing abdominal or gynaecological surgery without untoward sedative or cardiovascular effects.

The study examines the clinical characteristics of coronary artery ectasia (CAE) and its prognosis. Patients with CAE had higher incidence of hyperlipidemia, hypertension, and smoking than patients without CAE. The right coronary artery was the most commonly involved vessel among patients with CAE, while patients with isolated CAE had a dual involvement of the right coronary artery and left circumflex artery.
