Effect of an oxytocin protocol on secondary uterotonic use in patients undergoing Cesarean delivery.

PURPOSE: Protocol-driven oxytocin regimens can reduce oxytocin administration compared with a nonprotocol free-flow continuous infusion. Our aim was to compare secondary uterotonic use between a modified "rule of threes" oxytocin protocol and a free-flow continuous oxytocin infusion after Cesarean delivery. METHODS: We conducted a retrospective before-and-after study to compare patients who underwent Cesarean delivery between 1 January 2010 and 31 December 2013 (preprotocol) with patients who underwent Cesarean delivery between 1 January 2015 and 31 August 2017 (postprotocol). The preprotocol group received free-flow oxytocin administration and the postprotocol group received oxytocin according to a modified rule of threes algorithm. The primary outcome was secondary uterotonic use and the secondary outcomes included blood transfusion, hemoglobin value < 8 g·dL-1, and estimated blood loss. RESULTS: In total, 4,010 Cesarean deliveries were performed in 3,637 patients (2,262 preprotocol and 1,748 postprotocol). The odds of receiving secondary uterotonic drugs were increased in the postprotocol group (odds ratio [OR], 1.33; 95% confidence interval [CI], 1.04 to 1.70; P = 0.02). Patients in the postprotocol group were less likely to receive a blood transfusion. Nevertheless, the two groups were similar for the composite end point of transfusion or hemoglobin < 8 g·dL-1 (OR, 0.86; 95% CI, 0.66 to 1.11; P = 0.25). The odds of an estimated blood loss greater than 1,000 mL were reduced in the postprotocol group (OR, 0.64; 95% CI, 0.50 to 0.84; P = 0.001). CONCLUSIONS: Patients in the modified rule of threes oxytocin protocol group were more likely to receive a secondary uterotonic than those in the preprotocol group. Estimated blood loss and transfusion outcomes were similar.

RéSUMé: OBJECTIF: Les schémas thérapeutiques d'ocytocine basés sur un protocole peuvent réduire l'administration d'ocytocine par rapport à une perfusion continue en débit libre hors protocole. Notre objectif était de comparer l'utilisation secondaires d'agents utérotoniques entre un protocole modifié d'ocytocine en « règle de trois ¼ et une perfusion continue d'ocytocine à débit libre après un accouchement par césarienne. MéTHODE: Nous avons mené une étude rétrospective avant-après pour comparer les personnes ayant bénéficié d'une césarienne entre le 1er janvier 2010 et le 31 décembre 2013 (pré-protocole) avec les personnes ayant subi une césarienne entre le 1er janvier 2015 et le 31 août 2017 (post-protocole). Le groupe pré-protocole a reçu une administration d'ocytocine en débit libre et le groupe post-protocole a reçu de l'ocytocine selon un algorithme de règle de trois modifié. Le critère d'évaluation principal était l'utilisation secondaire d'agents utérotoniques et les critères d'évaluation secondaires incluaient la transfusion sanguine, un indice d'hémoglobine < 8 g·dL­1 et les pertes de sang estimées. RéSULTATS: Au total, 4010 accouchements par césarienne ont été réalisés chez 3637 patient·es (2262 pré-protocole et 1748 post-protocole). Les chances de recevoir des médicaments utérotoniques secondaires étaient plus élevées dans le groupe post-protocole (rapport de cotes [RC], 1,33; intervalle de confiance [IC] à 95 %, 1,04 à 1,70; P = 0,02). Les patient·es du groupe post-protocole étaient moins susceptibles de recevoir une transfusion sanguine. Néanmoins, les deux groupes étaient similaires en ce qui touchait au critère d'évaluation composite de transfusion ou d'hémoglobine < 8 g·dL­1 (RC, 0,86; IC 95, 0,66 à 1,11; P = 0,25). Les risques d'une perte de sang estimée supérieure à 1000 mL ont été réduits dans le groupe post-protocole (RC, 0,64; IC 95 %, 0,50 à 0,84; P = 0,001). CONCLUSION: Les patient·es du groupe du protocole d'ocytocine en règle de trois modifiée étaient plus susceptibles de recevoir un utérotonique secondaire que les personnes du groupe pré-protocole. Les pertes sanguines estimées et les résultats transfusionnels étaient similaires.

Intravenous Dexmedetomidine as an Adjunct to Neuraxial Anesthesia in Cesarean Delivery: A Retrospective Chart Review.

BACKGROUND: Dexmedetomidine is a selective α-2 agonist commonly used for sedation that has been used in obstetric anesthesia for multimodal labor analgesia, postcesarean delivery analgesia, and perioperative shivering. This study evaluated the role of intravenous dexmedetomidine to provide rescue analgesia and/or sedation during cesarean delivery under neuraxial anesthesia. METHODS: We conducted a single-center, retrospective cohort study of all parturients undergoing cesarean delivery under neuraxial anesthesia between December 1, 2018, and November 30, 2019, who required supplemental analgesia during the procedure. Patients were divided into two groups: patients who received intravenous dexmedetomidine (Dexmed group) and patients who received adjunct medications such as fentanyl, midazolam, ketamine, and nitrous oxide (Standard group). Primary outcome was incidence of conversion to general anesthesia. RESULTS: During the study period, 107 patients received adjunct medications. There was no difference in conversion to general anesthesia between the Dexmed group and the Standard group (6% (4/62) vs. 9% (4/45); p=0.718). In the Dexmed group, the mean dexmedetomidine dose received was 37 µg (range 10 to 140 µg). While the use of inotropic/vasopressor medications was common and similar in both groups, there was an increase in the incidence of bradycardia (Dexmed 15% vs. Standard 2%; p=0.042) but not hypotension (Dexmed 24% vs. Standard 24%; p=1.00) in the Dexmed group. CONCLUSION: In patients who required supplemental analgesia for cesarean delivery, those who received dexmedetomidine versus other medications had a similar rate of conversion to general anesthesia, a statistically significant increase in bradycardia, but no difference in the incidence of hypotension.

Creating a more quit-friendly national workforce? Individual layoff history and voluntary turnover.

Although Bureau of Labor Statistics data reveal that U.S. employers laid off over 30 million employees since 1994, virtually no research has addressed the behavior of layoff victims upon reemployment. In a first step, we investigate how layoffs shape voluntary turnover behavior in subsequent jobs. Utilizing a recently developed fixed effects specification of survival analysis, we find that a layoff history is positively associated with quit behavior. This effect is partially mediated by underemployment and job satisfaction in the postlayoff job. The remaining direct effect is consistent with the notion that layoffs produce a psychological spillover to postlayoff employment, which then manifests in quit behavior. We also find that layoff effects on turnover attenuate as an individual's layoffs accumulate and vary in magnitude according to the turnover "path" followed by the leaver.
