Brief summary

This study proposed applying intravenous Esketamine to cesarean section in parturient, detecting the plasma concentration of Esketamine in maternal blood, neonatal umbilical venous blood and umbilical arterial blood when the baby is delivered ketamine blood drug concentration, observing vital signs, adverse visual analog pain score (VAS), and sedation score (Ramsay) in parturient, neonatal Apgar score 1, 5 to 10 minutes after birth, the umbilical arterial blood gas and neurobehavioral scores (NBNA) 2, 24 hours after the birth. This study aims to address placental transfer, metabolism and analgesic and sedative effects in neonates and parturients of Esketamine so as to explore the feasibility, efficacy and safety of Esketamine as adjuvant medication for cesarean section.

Detailed description

1. case selection: A total of 600 patients (American Society of Anesthesiologists (ASA) grade I-II, aged 20-40 years,BMI 18.5-27) who underwent elective cesarean section were selected. 2. anesthesia methods: All patients were not given preoperative medication. After entering the operating room, peripheral venous connection was opened. Mindray multifunctional vital sign monitor continuously monitored electrocardiogram (ECG), heart rate (HR), pulse oxygen saturation (SpO2), systolic blood pressure (SBP), diastolic blood pressure (DBP) and Mean arterial pressure (MAP). After 5 minutes of waiting for patients with no obvious discomfort, 0.75% of ropivacaine was given 10ml before catheterization, and 0.75% of ropivacaine 3-5ml per hour maintained anesthesia 3. Grouping methods: A random number table was used to divide the patients into two groups with 300 patients in each group: The Esketamine group (group A) and the control group (group B) Esketamine group (Group A): at the beginning of the operation, 0.25mg/kg(2ml) Esketamine was administered intravenously as an adjuvant sedation and analgesia;Control group (Group B): 2ml normal saline was given intravenously at the beginning of the operation; 4. Observation items and methods 4.1 Forty patients were randomly selected from the Estroketamine group (group A) to detect the serum concentrations of Esketamine in umbilical vein blood and umbilical artery blood of neonates during fetal delivery. 4.2 maternal hemodynamic indexes such as heart rate (HR), mean arterial pressure (MAP) and respiratory mechanics indexes such as pulse oxygen saturation (SpO2) and shout at the end of the co2 partial pressure (PaCO2) are measured before anesthesia surgery at the beginning of the fetal childbirth at the end of the operation and operation after 1 hour when recording and compare the two groups of 4.3 maternal visual analog pain score (VAS) and sedation scores (Ramsay) and the time from uterine incision to fetal childbirth are measured before anesthesia surgery at the beginning of the fetal childbirthAt the end of the operation and operation after 1 hour record and compare the two groups of 4.4 respiratory system complications within 72 h in pregnant women (hypotension sinus bradycardia nausea and vomiting respiratory depression) are record. 4.5 Apgar score 1, 5, 10 minutes after birth, umbilical arterial blood gas and neurobehavioral scores (NBNA) 2 and 24 hours after the birth are record.

Design outcomes

Primary

MeasureTime frameDescription
Maternal pain intensityimmediately after fetal deliveryPain intensity was assessed with the numeric rating scale (NRS; an 11-point scale, with 0 indicating no pain and 10 indicating the worst pain)
Maternal sedation levelimmediately after fetal deliveryMaternal sedation level was assessed with Ramsay Sedation Scale (with 1 indicating restless; 2, completely awake, quiet, and cooperative; 3, drowsy but responding to verbal commands; 4, lightly asleep but responding to touch or pain; 5, asleep but slowly responding to touch or pain; and 6, deeply asleep and does not respond)

Secondary

MeasureTime frameDescription
Maternal sedation level at other timepointsbefore anesthesia, immediately after anesthesia, surgical incision, 5 minutes after study, end of surgery, 6 hours after surgery, and 12 hours after surgery. drug administration,Maternal sedation level at other timepoints were assessed with Ramsay Sedation Scale (with 1 indicating restless; 2, completely awake, quiet, and cooperative; 3, drowsy but responding to verbal commands; 4, lightly asleep but responding to touch or pain; 5, asleep but slowly responding to touch or pain; and 6, deeply asleep and does not respond)
systolic blood pressure, diastolic blood pressure, and mean blood pressurebefore anesthesia, immediately after anesthesia, at surgical incision, 5 minutes after study drug administration, immediately after fetal delivery, at end of surgery, and 1 hour after surgerysystolic and diastolic blood pressure were assessed by non-invasive blood pressure cuff,mean blood pressure was measured by the Calculation formula: Mean arterial pressure =(systolic pressure +2× diastolic pressure)/3
maternal heart ratebefore anesthesia, immediately after anesthesia, at surgical incision, 5 minutes after study drug administration, immediately after fetal delivery, at end of surgery, and 1 hour after surgerymaternal heart rate
Maternal pain intensity at other timepointsbefore anesthesia, immediately after anesthesia, surgical incision, 5 minutes after study, end of surgery, 6 hours after surgery, and 12 hours after surgery. drug administration,Maternal pain intensity at other timepoints were assessed with the numeric rating scale (NRS; an 11-point scale, with 0 indicating no pain and 10 indicating the worst pain)
Apgar score of newbornat 1 minute and 5 minute after birthApgar was assessed by appearance, pulse, grimace, activity, respiration. Each item was measured on a scale of 0, 1, and 2, respectively, with a maximum total score of 10.
postnatal umbilical vein blood gas pH valueResults of umbilical arterial blood gas analysis after birthpostnatal umbilical vein blood gas pH value

Other

MeasureTime frameDescription
Adverse events including hypotension, hypertension, bradycardia, tachycardia and desaturationAdverse events were recorded as Frequency of occurrence between the time the patient entered the operating room and the end of surgeryhypotension was defined as a systolic blood pressure decrease less than 20% of baseline, hypertension was defined as a systolic blood pressure increase greater than 20% of baseline, bradycardia was defined as a heart rate less than 60 beats per minute, tachycardia was defined as a heart rate greater than 100 beats per minute, and desaturation was defined as oxygen saturation less than 90%.
Mothers' memories of childbirthat 2 years after birthMothers' memories of childbirth was assessed by The Birth Memories and Recall Questionnaire (BirthMARQ),which focused on parents' positive, negative or mixed emotions at the birth/in recalling the event. Each item (e.g. 'my emotions at the time were extremely negative') was rated on a scale ranging from 1 (strongly disagree) to 7 (strongly agree).
offspring's neurodevelopment2 years after birthNeurodevelopment was measured by the Ages and Stages Questionnaire, third edition (ASQ-3).The ASQ-3 assesses 5 developmental domains: gross motor skills, fine motor skills, problem-solving ability, communication, and personal and social skills. Each domain is assessed by 6 questions ascertaining achievement of relevant skills and answered as yes (10 points), sometimes (5 points), or not yet (0 points). Scores for individual items are summed to give an overall continuous score for each of the 5 domains (possible range, 0-60).
