The goal of the present meta-analysis was to investigate postoperative analgesic properties of ketamine in pediatric patients.

Material and methods:

A comprehensive literature search was conducted to identify clinical trials that used ketamine as a perioperative analgesic compound in children and infants. Outcomes measured were postoperative analgesic consumption, pain intensity and duration of sensory block (when ketamine was used by caudal route) during HKI 272 the postoperative care unit (PACU) stay and the early postoperative period (6-24 h after leaving the operative room). The data from each

trial were combined to calculate the pooled odds ratios or standard mean differences and their 95% confidence intervals.

Results:

Thirty-five randomized, blinded controlled studies were retrieved from the literature. Systemic selleck inhibitor ketamine was effective in decreasing PACU pain intensity and analgesic

requirement but failed to influence early (6-24 h) pain intensity and analgesic requirement. Ketamine administered locally during tonsillectomy, decreased PACU and early (6-24 h) pain intensity and PACU analgesic requirements. Used as an adjuvant for caudal analgesia, ketamine increased the duration of sensory block and PACU analgesic requirement without impacting PACU pain intensity. Ketamine failed to exhibit a postoperative opioid-sparing effect.

Conclusions:

This meta-analysis found that administration of ketamine was associated with decreased PACU postoperative pain intensity and nonopioid analgesic requirement. However, ketamine

failed to exhibit a postoperative opioid-sparing effect.”
“The phase stability, nonstoichiometry, point defects, and magnetoresistance (MR) of polycrystalline Sr2FeMoO6-delta (SFMO) were studied. Thermogravimety Silmitasertib mw at 1200 degrees C in combination with x-ray diffraction shows that single-phase SFMO exists between -10.2 <= log p(O2) <= -13.7 at 1200 degrees C. At lower oxygen partial pressure mass loss signals reductive decomposition; at higher p(O2) a mass gain indicates oxidative decomposition into SrMoO4 and SrFeO3-x. The nonstoichiometry delta at 1200 degrees C was measured as function of p(O2) and oxygen vacancies were found to represent majority defects. The vacancy concentration increases with decreasing p(O2); a maximum nonstoichiometry of delta = 0.086 is observed close to the lower phase boundary. Samples with different delta were prepared at 1200 degrees C and various p(O2). The variation of structural parameters, magnetization, and MR is discussed in relation to oxygen nonstoichiometry delta. Maximum MR=6.5% at 298 K and 1 T is observed for samples with large delta.
