Investigation of bacteremia following nasotracheal intubation

Background : The aim of this study was to detect the risk of bacteremia from nasotracheal intubation in children undergoing dental treatment under general anesthesia.

The efficacy of caudal morphine or bupivacaine combined with general anesthesia on postoperative pain and neuroendocrine stress response in children.

Background : The aim of this study was to compare the effectiveness of caudal morphine and bupivacaine usage on surgical stress response in children undergoing abdominal and genitourinary surgery while keeping anesthesia depth constant utilizing the bispectral index analysis (BIS).

Laparoscopic cholecystectomy pain: effects of the combination of incisional and intraperitoneal levobupivacaine before or after surgery.

OBJECTIVES We aimed to investigate whether the timing of administration, using a combination of incisional and intraperitoneal levobupivacaine (0.25%), has an effect on the postoperative pain after laparoscopic cholecystectomy in a prospective, randomized, and controlled study. METHODS Sixty six patients were allocated to one of the three groups. Group BS received levobupivacaine before trocar site incision and intraperitoneal levobupivacaine immediately after pneumoperitoneum. Group AS received intraperitoneal levobupivacaine before trocars were withdrawn and incisional levobupivacaine administered at the end of surgery. Group C received no treatment. Data of intraoperative variables, postoperative pain relief, rescue analgesic consumption, and patient satisfaction were compared. RESULTS The intraoperative fentanyl consumption was found lower in Group BS, compared to Groups AS and C (p<0.05). VAS scores were lower in both Groups BS and AS, compared to Group C immediately after the operation (p<0.05). VAS scores were significantly decreased during the first two hours in Group AS, compared to Group C. The mean doses and number of patients needing rescue meperidine were lower in Group AS, compared to the Groups BS and C (p<0.05). CONCLUSION The combination of incisional and intraperitoneal levobupivacaine administered before or after surgery can reduce postoperative pain and analgesic and antiemetic consumption together with improved patient satisfaction. However, administering levobupivacaine before surgery might be advantageous for less intraoperative fentanyl consumption, while levobupivacaine after surgery is advantageous for less postoperative rescue analgesic requirement.

Tracheal intubation in intellectually disabled patients: Clinical usefulness of remifentanil and sevoflurane without a muscle relaxant:

Objective To compare two remifentanil doses (1 µg/kg and 2 µg/kg) in order to determine the preferred dose in intellectually disabled patients undergoing day care dental surgery under sevoflurane-induced general anaesthesia. Methods Patients were randomly assigned to receive either 1 µg/kg (group 1) or 2 µg/kg (group 2) remifentanil; both groups received 8% sevoflurane anaesthesia induction. All other conditions were identical in both groups. Heart rate (HR), mean arterial pressure (MAP) and intubation conditions were assessed. Results A total of 27/30 (90.0%) patients in group 1 and 29/30 patients (96.7%) in group 2 had acceptable intubation conditions. Remifentanil administration resulted in significant reductions in HR compared with baseline levels, in both groups. There were no significant between-group differences in HR at any timepoint. MAP decreased significantly compared with baseline in group 2 only. Conclusion Successful tracheal intubation in intellectually disabled patients can be accomplished with a combination of 1 µg/kg or 2 µg/kg remifentanil and 8% sevoflurane anaesthesia induction, without the requirement for neuromuscular blocking drugs.
