Objective The overall intubation conditions after tracheal intubation with remifentanil, propofol, and sevoflurane at 1.0 minimum alveolar concentration (MAC) are worse than with rocuronium at 0.45 mg/kg. Therefore, we compared the intubation conditions and laryngeal morbidity (vocal cord injuries, hoarseness, and sore throat) with sevoflurane at 1.2 and 1.4 MAC versus 1.0 MAC. Methods In this prospective clinical trial, 90 patients were randomized to 3 groups: the sevoflurane 1.0, 1.2, and 1.4 MAC groups. At 3 min, tracheal intubation was performed and the patients' intubation conditions were assessed. The vocal cords were examined for injury by videolaryngoscopy. Additionally, the incidence and severity of laryngeal morbidity were compared between women and men. Results Acceptable intubation conditions were seen in 72% of the patients without significant differences between the groups. Overall, vocal cord injuries (oedema) occurred in three (4%) patients. Women reported sore throat more often than men (51% vs. 21%, respectively). Conclusions Intubation conditions were not improved with higher sevoflurane concentrations. The incidence and severity of sore throat were greater in women than men.. ClinicalTrials.Gov: NCT 01896245.

Postoperative sore throat (POST) is a frequent complication caused by mucosal trauma to the pharyngeal, laryngeal, and tracheal airway after endotracheal intubation. We compared the effectiveness of Siccoral, Strefen, and Stomatovis treatments in alleviating POST.. This prospective, randomized, single-blinded, controlled trial compares the incidence of POST with Strefen lozenges, Siccoral spray, or Stomatovis gargle. Three hundred and twenty American Society of Anesthesiologists class I-III patients undergoing elective genitourinary surgery under general orotracheal anesthesia were randomly allocated to four groups of 80 patients each. In the postoperative awakening unit and during related services, POST was evaluated by a blinded anesthesiologist at 0, 1, 6, and 24 h post extubation.. The highest incidence of POST occured at 0 and 1 h post extubation in all groups (P = 0.002 × 10(-7), P = 0.004 × 10(-6), respectively). A significantly lower incidence of POST was observed in Strefen and Siccoral groups at 0 and 1 h compared to Control group (Strefen: P = 0.004 × 10(-2), P = 0.007 × 10(-4); Siccoral: P = 0.003 × 10(-8), P = 0.007 × 10(-5), respectively). A significantly lower incidence of POST was observed with Siccoral treatment at 0 h post extubation (P = 0.002 vs. Strefen treatment). Although POST incidence was not significantly different between the Stomatovis and Control groups, it was lower in the Stomatovis group at 0 and 1 h (P = 0.026 and 0.013, respectively). The incidence of POST was similar in all groups at 6 and 24 h post extubation (P = 0.141 and 0.426, respectively).. Siccoral and Strefen can be effective in relieving POST in the early hours after extubation.

The need for muscular relaxation to improve intubating conditions and to reduce the incidence of laryngeal morbidity is still controversial. The aim of this study was to determine the incidence of symptomatic laryngeal injuries (SLI) and of acceptable intubating conditions (including both good and excellent conditions), both with and without cisatracurium during induction of anesthesia, along with moderate doses of remifentanil and propofol.. In this prospective, randomized double-blind equivalence trial, the intubating conditions were compared in 130 ASA I or II female patients. All subjects received remifentanil 2 microg x kg(-1) i.v. and propofol 2.5 mg x kg(-1) i.v., with either cisatracurium 0.15 mg x kg(-1) i.v. (group Cisatracturium), or saline (group Placebo). Tracheal intubating conditions were assessed with the Copenhagen Score. A systematic screening for postoperative hoarseness and sore throat was performed 24 and 48 hr after anesthesia, followed by a nasofibroscopic examination when laryngeal symptoms persisted at 48 hr.. Twenty-four hr after anesthesia, the incidence of postoperative hoarseness and sore throat in the Cisatracurium and Placebo groups was 26.5% and 21.5%, respectively, and 48 hr after anesthesia, the incidence was 7.8% and 6.1%, respectively (P = 0.32 and P = 0.50 between groups, respectively). In the clinically evaluable population, the incidence of SLI, assessed at 48 hr by nasofibroscopy, was equivalent in both groups, 1.6% vs 1.5% in group Placebo and group Cisatracurium, respectively (P < 0.001 for equivalence test), as was the occurrence of acceptable intubating conditions (95.4% vs 100%, P < 0.05 for equivalence test). However, the occurrence of excellent intubating conditions was more frequent in group Cisatracurium than in group Placebo (P = 0.0003).. Following induction of anesthesia with propofol and moderate-dose remifentanil, cisatracurium did not confer a higher rate of good-to-excellent conditions for tracheal intubation, nor did muscle relaxation with cisatracurium decrease the rate of SLI after tracheal intubation.

The new fluoroquinolones WCK 771, WCK 1152 and WCK 1153 were developed to overcome quinolone resistance in Gram-positive bacteria. The activity of these new quinolones was tested against 159 clinical isolates of Streptococcus pneumoniae and 52 clinical isolates of Streptococcus pyogenes using the microbroth dilution method.. MIC50/MIC90 values (mg/L) of WCK 771, WCK 1152 and WCK 1153 for quinolone-susceptible S. pneumoniae (n = 119; 54 penicillin G-susceptible, 53 penicillin G-intermediate, and 12 penicillin G-resistant strains) were 0.25/0.5, 0.03/0.06 and 0.016/0.03, respectively. MIC50/MIC90 values (mg/L) for quinolone-resistant pneumococci (n = 40) increased to 4/16, 0.25/1 and 0.125/0.5, respectively. Against S. pyogenes, WCK 771, WCK 1152 and WCK 1153 were also highly active with MIC50/MIC90 values (mg/L) of 0.25/0.25, 0.03/0.06 and 0.03/0.03, respectively.. Overall, WCK 771 was highly active against quinolone-susceptible, but not against quinolone-resistant S. pneumoniae, whereas WCK 1152 and WCK 1153 were more potent and were able to overcome quinolone resistance in both S. pneumoniae and S. pyogenes.
