Effects of supplemental oxygen on maternal and neonatal oxygenation in elective cesarean section under spinal anesthesia: a randomized controlled trial.

ABSTRACT: The use of supplemental oxygen in uncomplicated cesarean deliveries under spinal anesthesia has been thoroughly investigated during recent decades. The aim of this study was to determine the benefits for both mother and infant of administering supplemental, low-dose oxygen via a nasal cannula versus having no supplement (i.e., room air only). Healthy parturients at term undergoing elective cesarean section under spinal anesthesia were randomly allocated into two groups: an oxygen group (n = 170), who received 3 LPM oxygen via a nasal cannula; and a room-air group (n = 170), who were assigned to breathe room air. Maternal oxygen saturation was measured continuously by using pulse oximeter. The desaturation was determined by oxygen saturation <94% over 30 seconds. Umbilical cord gases and Apgar scores were collected followed delivery of the infant. All maternal desaturation events occurred in 12 parturients assigned to the room-air group. Most events were concurrent with hypotension. The umbilical venous partial pressure of oxygen was significantly higher in the oxygen group. The other blood gas measurements and Apgar scores were not significantly different between the two groups. Based on our findings, the use of supplemental oxygen could prevent maternal desaturation resulting from receiving sedation and intraoperative hypotension.

Project description:BACKGROUND:Anticoagulant therapy during pregnancy is widely used due to the increasing awareness of maternal hypercoagulability. Few studies have reported the use of minimally invasive spinal anesthesia in these parturients. The objective of this study was to evaluate the safety and feasibility of minimally invasive spinal anesthesia in parturients with anticoagulation therapy undergoing cesarean section. METHODS:This was a randomized, controlled study conducted in 239 parturients using anticoagulants and undergoing selective cesarean section. 37 parturients withdrew, and finally parturients received spinal anesthesia using 27gauge pen type fine spinal needles (experimental group, n?=?110) and 22gauge traditional spinal needles (control group, n?=?92). The primary efficacy outcomes included low back pain (LBP) and postdural puncture headache (PDPH) after delivery. Secondary efficacy outcomes included visual analogue scale during subarachnoid puncture (VASdural), difference between visual analogue scale (VAS) during peripheral venipuncture and VASdural (?VAS), VAS of back puncture point 24, 48 and 72?h after operation (VASdural-24?h, VASdural-48?h and VASdural-72?h, respectively), maternal satisfaction and hospitalization stay. RESULTS:No parturient had PDPH and was suspected with spinal or intracranial haematoma in two groups. There was no significant difference in VASlbp-24?h, VASlbp-48?h and VASlbp-72?h (P?=?0.056; P?=?0.813; P?=?0.189, respectively) between two groups. In experimental group, VASdural (P?=?0.017), ?VAS (P?=?0.001) and VASdural-24?h (P?<?0.0001) were lower, whereas maternal satisfaction was higher (P?=?0.046). There was no significant difference in VASdural-48?h, VASdural-72?h, urination function, strength recovery and hospitalization stay (P?=?0.069; P?=?0.667; P?=?0.105; P?=?0.133; P?=?0.754, respectively) between the two groups. CONCLUSIONS:Minimally invasive spinal anesthesia provided lower VASdural, VASdrual-24?h and a higher maternal satisfaction. Hence, it is considered as a safe, reliable and reasonable option for cesarean section parturients during maternal anticoagulation therapy with normal platelet count and coagulation time. TRIAL REGISTRATION:This study was registered at www.ClinicalTrials.gov at November 11th, 2016 ( NCT02987192 ).

Project description:BackgroundSpinal anesthesia is the standard technique for elective cesarean section, but the incidence of maternal hypotension in this setting is reportedly about 80%, without any prophylactic management. Vasopressors are the most reliable method for counteracting the hypotension induced by spinal anesthesia. However, studies investigating the effects of vasopressors have yielded inconsistent and debatable results. Therefore, we plan to conduct a systematic review and network meta-analysis to identify the most effective vasopressor to prevent maternal hypotension, and to decrease fetal acidosis in women undergoing spinal anesthesia for elective cesarean section.MethodsA systematic and comprehensive search to detect all the randomized controlled studies on vasopressors for the management of maternal hypotension during cesarean section under spinal anesthesia will be performed using information in the databases, MEDLINE, EMBASE, the Cochrane Central Register of Controlled Trials (CENTRAL), and Google Scholar, beginning from their inception to October 2018. We will conduct a network meta-analysis to combine the direct and indirect comparisons of the vasopressors. We will use the surface under the cumulative ranking curve (SUCRA) values and rankograms to present the hierarchy of vasopressors. A comparison-adjusted funnel plot will be used to assess the presence of small-study effects. The quality of the studies included will be assessed using the risk of bias tool. All statistical analyses will be performed using Stata SE version 15.0.Ethics and disseminationThis systematic review and meta-analysis will be published in a peer-reviewed journal. Ethical approval and informed consent are not required, as the study will be a literature review and will not involve direct contact with patients or alterations to patient care.Trial registration numberThe protocol for this review has been registered in the PROSPERO network (registration number: CRD42018111852).

Project description:BACKGROUND:Spinal anesthesia is a form of regional anesthesia frequently used in various lower abdominal, orthopedic, obstetric operations such as a cesarean delivery. The most common local anesthetic used for spinal anesthesia in obstetric and non-obstetric surgery is bupivacaine which can be utilized as an isobaric or hyperbaric solution, producing differences in maternal hemodynamic changes. Against this backdrop, the study aims to compare the effects of isobaric and hyperbaric bupivacaine on maternal hemodynamic alterations after administering spinal anesthesia for elective cesarean delivery at Gandhi Memorial Hospital, Addis Ababa, Ethiopia. METHODS:A hospital-based prospective cohort study design was employed for the period December 1, 2017 to January 30, 2018. A total of 100 parturient were involved, with one group exposed to isobaric bupivacaine and the other to hyperbaric bupivacaine to observe their effects on maternal hemodynamic changes post spinal anesthesia. The participants were selected through systematic random sampling. Data analysis was performed using SPSS (version 20) through descriptive statistic, independent sample t-test, Mann-Whitney U-test, Fisher's exact test, and Chi-square test were used. P values of <0.05 was assumed as statistically significant for all tests. RESULTS:The incidence of hypotension was found to be greater in isobaric than hyperbaric groups (82% vs. 60% respectively; p = 0.015). No statistical significant differences were found in mean arterial pressure value at baseline, but, statistically significant changes were observed among the groups (p <0.05) at all study timing after spinal anesthesia, except at 30thmin. No statistically significant differences were seen in the mean heart rate variability after spinal anesthesia at all periods, except the 15th minute (p = 0.033). A greater rate of vasopressor was used in the isobaric group as compared to the hyperbaric group (36% vs. 14% respectively; p = 0.011). CONCLUSION:Baricity is a significant factor in maternal hemodynamic changes in the parturient for elective cesarean section. Isobaric bupivacaine produces greater change in blood pressure and incidence of hypotension and entails a greater vasopressor requirement than hyperbaric bupivacaine after spinal anesthesia for elective cesarean section.
