A long-term survivor of Bland-White-Garland syndrome with systemic collateral supply: a case report and review of the literature.

BACKGROUND: Bland-White-Garland syndrome (anomalous origin of the left coronary artery from the pulmonary artery) is a rare disease which may result in myocardial infarction, congestive heart failure and sometimes death during the early infantile period. CASE PRESENTATION: A successfully treated case of a 45-year-old mother of 2 children with Bland-White-Garland syndrome and concomitant severe mitral regurgitation is presented. Subsequent therapy consisted of ligation of the anomalous origin of the left coronary artery, anastomosis of the left internal mammary artery to the left anterior descending branch and mitral valve replacement. Continuous blood flow from the left coronary artery ostium during extracorporeal circulation and aorta clamping suggested systemic collateral supply. CONCLUSIONS: Recognition and diagnosis of Bland-White-Garland syndrome is important due to its potentially life-threatening complications.

Preincisional local infiltration of levobupivacaine vs ropivacaine for pain control after laparoscopic cholecystectomy.

BACKGROUND: Postoperative pain is less intense after laparoscopic surgery than after open surgery. However, patients may gain additional benefit from a preincisional local infiltration of anesthetic. The aim of this study was to compare the analgesic efficacy of two local anesthetics, ropivacaine and levobupivacaine, for tissue infiltration as a means of improving postoperative pain control after laparoscopic cholecystectomy. METHODS: Using a randomized, double-blind study design, 57 American Society of Anesthesiologists (ASA) I and II patients scheduled for laparoscopic cholecystectomy were randomly assigned to receive local infiltration with 0.9% saline solution (Placebo group, n = 18), ropivacaine 1% (Rop group, n = 20), or levobupivacaine 0.5% (Lev group, n = 19). The local anesthetic was administered, prior to trocar placement, using the same technique and delivering the same volume (20 ml) for all three groups. The anesthetic technique was standardized for all groups. Postoperative pain was rated at 2 h, 4 h, and 24 h postoperatively by visual analogue scale (VAS) score. Cumulative analgesic consumption and adverse effects were also recorded. Data were analyzed by analysis of variance (ANOVA), followed by a post hoc test. RESULTS: The Lev and Rop groups did not differ significantly in their VAS scores at 2 h postoperatively, but the Lev group experienced significantly ( p < 0.001) less pain than the Placebo and Rop groups at 4 h and 24 h postoperatively. The Rop group registered significantly lower VAS scores ( p < 0.001) than the Placebo group at 4 h postoperatively. Additionally, the consumption of analgesics was significantly lower in the Lev group than in the Rop ( p < 0.01) and Placebo ( p < 0.001) groups, and patients in the Rop group consumed significantly less analgesics ( p < 0.001) than the to patients in the Placebo group. CONCLUSION: Local tissue infiltration with levobupivacaine is more effective than ropivacaine in reducing the postoperative pain associated with laparoscopic cholecystectomy.

Sufentanil or clonidine for blunting the increase in intraocular pressure during rapid-sequence induction.

BACKGROUND AND OBJECTIVE: The aim was to determine if the intravenous administration of sufentanil or clonidine before the induction of anaesthesia could obtund the increase of intraocular pressure associated with rapid-sequence induction. METHODS: Thirty-two ASA I-II patients with no history of eye illness scheduled for elective non-ophthalmic surgery were randomly assigned to receive either sufentanil 0.05 microg kg(-1) i.v. (Group A, n = 15) or clonidine 2 microg kg(-1) i.v. (Group B, n = 17) prior to induction. General anaesthesia was induced with thiopental (5 mg kg(-1)) followed by succinylcholine 1 mg kg(-1) to facilitate tracheal intubation. The general anaesthetic technique was standardized in both groups. Intraocular pressure was measured using the Schioetz tonometer just before the succinylcholine administration (t0), just before tracheal intubation (t1) and immediately after intubation (t2). Mean arterial pressure and heart rate were recorded at the same time intervals. RESULTS: Intraocular pressures were similar in both groups at t0, but the sufentanil group had significantly lower values compared with the clonidine group just before (t1) and immediately after tracheal intubation (t2). CONCLUSIONS: Sufentanil is effective in blunting the increase in intraocular pressure caused by rapid-sequence induction with succinylcholine, while clonidine did not seem to have any effect in intraocular pressures just before (t1) and just after (t2) intubation.

Tropisetron vs ondansetron for prevention of postoperative nausea and vomiting after laparoscopic cholecystectomy: a randomized double-blind, placebo-controlled study.

BACKGROUND: Postoperative nausea and vomiting are observed in increased frequency after laparoscopic surgery. This study was performed in order to compare the efficacy of two 5-hydroxytryptamine-3 (5-HT3) receptor antagonists, ondansetron and tropisetron, in preventing postoperative nausea and vomiting (PONV) after laparoscopic cholecystectomy. METHODS: Using a randomized, double-blind study design, 87 ASA I and II patients scheduled for laparoscopic cholecystectomy were randomly assigned to receive 4 mg ondansetron (Group A, n = 29), 5 mg tropisetron (Group B, n = 31), or placebo (Group C, n = 27) intravenously (IV) before induction of anesthesia. The end points evaluated were frequency of nausea, nausea intensity rated on a scale from 1 (mild) to 5 (most severe), frequency of vomiting, and need for rescue antiemetics. These parameters were measured immediately after surgery (0 h), at 3 h, 6 h, and 12 h postoperatively. RESULTS: The frequency of nausea was significantly higher in group A (31.2%) compared to group B (14%) at 12 h postoperatively (p <0.01). However, patients of group A had significantly lower nausea scores at 3 h postoperatively compared to group B. Postoperative vomiting occurred in 13.8% of patients in group A and 9.6% of patients in group B throughout the whole study period (p = n.s.). The need for rescue antiemetics was similar between groups A and B. Both groups were superior to placebo concerning all studied parameters. CONCLUSION: Our results show that ondansetron may be more effective in controlling nausea intensity during the first 3 h after laparoscopic cholecystectomy, while tropisetron has a longer-acting activity, with a major impact on nausea frequency at 12 h postoperatively.

Preincisional intravenous low-dose ketamine and local infiltration with ropivacaine reduces postoperative pain after laparoscopic cholecystectomy.

BACKGROUND: The preincisional use of ketamine combined with local tissue infiltration with Ropivacaine may reduce noxious input during surgery. The goal of this study was to examine whether this combination improves postoperative pain control after laparoscopic cholecystectomy. METHODS: A total of 55 patients were randomly assigned to one of three groups. Group 1 received placebos preincisional. Group 2 received preincisional saline IV and local infiltration with 20 ml ropivacaine (10 mg/ml). Group 3 received preincisional ketamine 1 mg/kg IV and local infiltration with 20 ml ropivacaine (10 mg/ml). Postoperative pain was rated at 0, 3, 6, 12, 24, and 48 h postoperatively by visual analogue scale scores (VAS). Cumulative analgesic consumption and time until first analgesic medication request were recorded. RESULTS: Group 3 experienced significantly (p < 0.05) less pain than group 2 at 6 h and 12 h postoperatively. Groups 2 and 3 did not differ significantly by VAS at 0 h, 3 h, 24 h, and 48 h. Group 1 had significantly higher VAS scores than groups 2 and 3 at 0 h, 3 h, 6 h, 12 h, and 24 h postoperatively. The consumption of analgesics was significantly higher in group 1 than in groups 2 and 3. Although the consumption of analgesics was higher in group 3 than in group 2, this difference did not reach statistical significance. The time to first request for analgesics was significantly longer in groups 2 and 3 than in group 1, with no statistical difference between groups 2 and 3. CONCLUSION: Preincisional treatment with low-dose IV ketamine and local infiltration with ropivacaine 1% reduces postoperative pain after laparoscopic cholecystectomy.
