Observational Study
Hypoxia inducible factor-1 alpha and prolinhydroxlase 2 polymorphisms in patients with severe sepsis: a prospective observational trial.
Hypoxia-inducible-factor-1α (HIF-1α) and HIF-1 degrading prolyl-hydroxylases (PHD) are key regulators of the hypoxic-inflammatory response. Functionally active genetic variants in the HIF-1α (C/T; Single Nucleotide Polymorphism (SNP) rs11549465) and the PHD2 gene (EGLN1; C/T; SNP rs516651 and T/C; SNP rs480902) are associated with altered HIF-1α mRNA nuclear translocation and an altered adaptation to hypoxia. Furthermore, the HIF system is important in surviving inflammatory disorders and sepsis. Thus, we tested the hypotheses, that SNPs in the HIF-1α or PHD2 genes are (1) common in Caucasians, with 2) the HIF-1α genetic variant being associated with an altered HIF-1α mRNA expression; and 3) independent risk factors for 30-day mortality in severe sepsis. ⋯ Genetic variants in HIF-1α and PHD2 genes exist in Caucasians but do not appear to alter 30-day mortality in sepsis.

Despite international data indicating that Enhanced Recovery After Surgery (ERAS) programs, which combine evidence-based perioperative strategies, expedite recovery after surgery, few centers have successfully adopted this approach within the U.S. We describe the implementation and efficacy of an ERAS program for colorectal abdominal surgery in a tertiary teaching center in the U.S. ⋯ These results confirm that a multidisciplinary, iterative, team-based approach is associated with a reduction in hospital stay and an acceleration in recovery without increasing readmission rates.

Randomized Controlled Trial Comparative Study
Dexmedetomidine versus remifentanil for sedation during awake intubation using a Shikani optical stylet: a randomized, double-blinded, controlled trial.
The purpose of this study was to compare the efficacy and safety of dexmedetomidine versus remifentanil for sedation during awake intubation using a Shikani optical stylet (SOS). ⋯ Both dexmedetomidine and remifentanil are effective sedatives for awake intubation using an SOS. Although the first attempt success rates were similar, patients sedated with remifentanil tolerated the tracheal tube better after intubation with moderately increased risk of desaturation.

Randomized Controlled Trial Comparative Study
Dexmedetomidine-ketamine versus Dexmedetomidine-midazolam-fentanyl for monitored anesthesia care during chemoport insertion: a Prospective Randomized Study.
Dexmedetomidine as a sole agent showed limited use for painful procedures due to its insufficient sedative/analgesic effect, pronounced hemodynamic instability and prolonged recovery. The aim of this study was to compare the effects of dexmedetomidine-ketamine (DK) versus dexmedetomidine-midazolam-fentanyl (DMF) combination on the quality of sedation/analgesia and recovery profiles for monitored anesthesia care (MAC). ⋯ The DK and DMF groups showed comparable recovery time, onset time, cardiorespiratory variables, and analgesia. However, the DMF group showed a better sedation quality and satisfaction scores despite the lower infusion rate of dexmedetomidine, and a higher incidence of BIS < 60 than the DK group.

Randomized Controlled Trial Comparative Study
Effects of remifentanil and remifentanil-alfentanil administration on emergence agitation after brief ophthalmic surgery in children.
Sevoflurane is commonly usedin pediatric anesthesia due to its non-irritating airway properties, and rapid induction and emergence. However, it is associated with emergence agitation (EA) in children. EA may cause injury to the child or damage to the surgical site and is a cause of stress to both caregivers and families. The efficacy of remifentanil and additional alfentanil on EA in the pediatric patients underwent ophthalmic surgery with sevofluraneanesthesiawas not well evaluated to date. This study was designed to compare the effects of remifentanil and remifentanil plus alfentanil on EA in children undergoing ophthalmic surgery with sevofluraneanesthesia. ⋯ The administration of remifentanil to children undergoing ophthalmic surgery undersevoflurane anesthesia reduced the incidence of EA without clinically significant hemodynamic changes. However, the addition of alfentanil(5 μg/kg)10 min before the end of surgery provided no additional benefit compared withremifentanil alone.
