Videolaryngoscopy during Urgent Cesarean Delivery: Association with Neonatal Intensive Care Unit Admission.

Parturients are at increased risk for difficult airway management with subsequent fetal complications. Videolaryngoscopy was opined to be the new standard of airway care to facilitate orotracheal intubation under urgent care conditions. We examined in parturients requiring general anesthesia for urgent cesarean delivery the association of the type of laryngoscopy technique and time required to facilitate orotracheal intubation with the incidence of subsequent neonatal intensive care unit (NICU) admission. Following institutional review board approval, 431 parturients aged 18 years and older who underwent urgent cesarean section requiring general anesthesia were entered into this study. Patient characteristics, maternal comorbidities, and indications for urgent cesarean delivery were collected from the electronic medical records from January 2013 to November 2018. Orotracheal intubation times by type of laryngoscopy (video or direct) and NICU admission rates also were collected. A measure of effect size, risk differences with 95% confidence intervals (CIs), were calculated for the likelihood of NICU admission by difficult orotracheal intubation and by type of laryngoscopy used to secure the airway. Videolaryngoscopy as the primary type of laryngoscopy was used in 24.1% (95% CI 20.3%-28.3%) of general anesthetics. The incidence of difficult orotracheal intubation was 4.4% (95% CI 2.8%-6.7%), with a higher incidence observed with videolaryngoscopy (8.7%) than with direct laryngoscopy (3.1%) and a risk difference of 5.6% (95% CI 0.001%-11.3%). The incidence of NICU admission was 38.4% (95% CI 34.0%-43.1%). Times for successful orotracheal intubation were longer with videolaryngoscopy. Videolaryngoscopy had a higher association for NICU admission (47%) than for direct laryngoscopy (36%), with a risk difference of 11.4% (95% CI 0.01%-22.3%). Videolaryngoscopy did not decrease the incidence of difficult orotracheal intubation, and it did not decrease the time associated with orotracheal intubation. Videolaryngoscopy was associated with a higher association of NICU admission. These results suggest that videolaryngoscopy does not supplant direct laryngoscopy as the standard of care for orotracheal intubation under urgent care conditions of general anesthesia for cesarean section.

Comparing the Effects of Midazolam and Ondansetron in Postoperative Nausea and Vomiting

Background: Nausea and vomiting after a cesarean section (CS) are among the common side effects that cause dissatisfaction among doctors. The aim of this study was to compare the effects of intravenous midazolam and ondansetron on the reduction of nausea and vomiting after spinal anesthesia in CS. Methods: This double-blind clinical trial study was conducted on CS candidates who underwent spinal anesthesia (N=80). After spinal anesthesia, the patients were randomly divided into two groups. Midazolam was administered to one group and ondansetron to the other group. The severity of nausea, the severity of vomiting, and the degree of satisfaction were recorded during surgery and recovery. Results: No significant difference was observed between the two groups in terms of the severity of nausea and vomiting. In addition, the results demonstrated that the level of satisfaction in the midazolam group was higher than that in the ondansetron group, but this difference was not statistically significant (P<0.05). Conclusion: The results of this study showed that midazolam can reduce nausea and vomiting. On the other hand, the results confirmed that both ondansetron and midazolam can have the same effects on reducing nausea and vomiting.

A Comparison of Norepinephrine versus Phenylephrine to Prevent Hypotension after Spinal Anesthesia for Cesarean Section: Systematic Review and Meta-Analysis.

This systematic review and meta-analysis aimed to compare the effects of using phenylephrine or norepinephrine on the pH and base excess (BE) of the umbilical artery and vein in parturients undergoing cesarean section. The study protocol was registered in INPLASY. Independent researchers searched Ovid-Medline, Ovid-EMBASE, and Cochrane Central Register of Controlled Trials (CENTRAL) databases and Google Scholar for relevant randomized controlled trials (RCTs). The primary outcome of this study was the umbilical artery (UA) or umbilical vein (UV) pH as neonatal condition at birth, and the secondary outcome was the UA or UV BE as an additional prognostic value over the measurement of umbilical pH. There was no evidence of a difference between phenylephrine and norepinephrine for overall, UA, and UV pH (mean difference (MD) -0.001, 95% confidence interval (CI) -0.004 to 0.007; MD 0.000, 95%CI -0.004 to 0.004; and MD 0.002, 95%CI -0.013 to 0.017). There was also no evidence of a difference between phenylephrine and norepinephrine for overall, UA, and UV BE (MD 0.096, 95% CI -0.258 to 0.451; MD 0.076, 95%CI -0.141 to 0.294; and MD 0.121, 95%CI; -0.569 to 0.811). A meta-regression showed that factors such as umbilical artery or vein, infusion method, single or twin, and the number of parturients per study had no effect on the UA pH, UV pH, UA BE, or UV BE. No evidence of publication bias was detected. There was no evidence of a difference between phenylephrine and norepinephrine for umbilical pH and BE. A subgroup analysis and meta-regression also did not show evidence of differences.

Comparison of Spinal Versus General Anesthesia for Caesarean Section in Patients with Severe Preeclampsia

Comparison of Spinal Versus General Anesthesia for Caesarean Section in Patients with Severe Preeclampsia

Norepinephrine versus phenylephrine affects prethrombotic response in patients undergoing cesarean section under spinal anesthesia: a randomized, double-blind, controlled study.

Venous thromboembolism (VTE) is one of the most common and serious complications of cesarean section in parturients. Norepinephrine (NE) has been shown to activate coagulation. The aim of this study was to compare the effect of a fixed-rate prophylactic norepinephrine infusion and a fixed-rate prophylactic phenylephrine（PHE） infusion under spinal anesthesia for caesarean section on the prethrombotic response. Sixty-six women undergoing cesarean section under spinal anesthesia were randomly assigned to the NE group or PHE group, starting simultaneously with the administration of the subarachnoid solution, a "study drug" solution containing either NE or PHE was pumped intravenously at a constant rate of 15 ml/h until the end of the operation. Plasma coagulation factor VIII activity (FVIII: C), Fibrinogen, and D-dimer levels were measured in blood samples obtained on admission to the operating theatre and at the end of the procedure. Compared with preoperative levels, there were no significant differences in postoperative fibrinogen and D-dimer levels in the NE group, except for a decrease in FVIII: C levels (P = 0.003). However, postoperative levels of FVIII: C (P = 0.009), fibrinogen (P = 0.035) and D-dimer (P = 0.025) were increased in the NE group compared with postoperative levels in the PHE group. NE does not affect the maternal prethrombotic response and can be safely used in cesarean sections. Compared with PHE infusion, NE infusion increased the level of coagulation molecules, suggesting that NE maybe more beneficial for women with high intraoperative bleeding requiring hemostasis.

Peculiarities of anesthesia for caesarean section in patients with gestational diabetes mellitus

BACKGROUND: Women with gestational diabetes mellitus are at high risk of operative delivery. Meanwhile, hyperglycemia affects the metabolism of narcotic analgesics, while increasing their need. Thus, the anesthesiologist is faced with the question of what method of anesthesia to choose for a particular cesarean section. AIM: The aim of this study was to estimate the features of the perioperative period of cesarean section in patients with gestational diabetes mellitus. MATERIALS AND METHODS: This prospective, controlled, single-center study enrolled 101 patients who were delivered by planned cesarean sections from April to November 2023. Group 1 included patients with gestational diabetes mellitus on diet therapy (n = 28), group 2 comprised patients with gestational diabetes mellitus on insulin therapy (n = 29), and group 3 (control) included women with a normal pregnancy without carbohydrate metabolism disturbances (n = 44). RESULTS: The highest initial values of mean arterial pressure were in group 2 and amounted to 91.8 ± 7.0 mmHg. In group 1, the mean arterial pressure was within 89.1 ± 6.4 mmHg, and in group 3, that was 85.9 ± 9.1 mmHg, which was significant (p 0.05). The sympathetic block developed longer in patients of group 2. In group 1, the sensory block was recorded at the ThIV–ThV level after 10.1 minutes and the motor block (Bromage score 3) after 12.2 minutes compared to 7.8 and 8.6 minutes, respectively, in group 2, and 4.5 and 5.1 minutes, respectively, in group 3. In group 2, authors observed the most rapid regression of the block (79.4 minutes after the injection of local anesthetic), which required an earlier start of the transversus abdominis plane block (after 65.3 minutes). The sympathetic block regressed after 86.2 and 138.1 minutes in patients of groups 1 and 3, respectively (p 0.05), when the transversus abdominis plane block was performed. Thus, immediately after cesarean section, women with gestational diabetes mellitus (especially on insulin therapy) had a higher need for analgesics than those without gestational diabetes mellitus. CONCLUSIONS: During cesarean section under spinal anesthesia in patients with gestational diabetes mellitus, the rate of development of the sympathetic block is reduced (especially in women who received insulin therapy). At the same time, block regression in these patients occurs much faster, which requires an earlier start of postoperative anesthesia. An increased need for systemic analgesics has been demonstrated during the postoperative period in women with gestational diabetes mellitus, mainly with insulin therapy.

Comparison of Fentanyl With Midazolam As Adjuvants to Levobupivacaine in Spinal Anesthesia for Cesarean Sections: A Randomized Controlled Trial.

Background and objectives Spinal anesthesia stands as a cornerstone for patients undergoing lower segment cesarean section (LSCS), offering advantages like faster onset and high block density. Levobupivacaine, known for its high potency and long-acting nature, has a slower onset. The safety of intrathecal fentanyl or midazolam is evaluated as an adjuvant to levobupivacaine in parturients. This study aims to compare the duration of postoperative analgesia provided by fentanyl or midazolam added to 0.5% hyperbaric levobupivacaine in elective cesarean sections. Secondary objectives include evaluating the onset and duration of sensory and motor blockade and the incidence of nausea and vomiting. Identifying the more effective adjuvant will help optimize spinal anesthesia protocols, improve postoperative outcomes, and enhance patient comfort and recovery. Methods This study was conducted at SRM Medical College Hospital and Research Centre, Chennai, India, over six months (May 1, 2023, to October 1, 2023). A total of 90 patients undergoing elective LSCS received spinal anesthesia in a prospective randomized double-blinded controlled trial. Patients were allocated to three groups: Group A received levobupivacaine with fentanyl, Group B received levobupivacaine with midazolam, and Group C received levobupivacaine with normal saline. Block characteristics, postoperative analgesia, hemodynamic stability, and complications were assessed. Assessments were conducted at specified time points: intraoperatively, every five minutes for the first 30 minutes, every 10 minutes for the next hour, every two hours for six hours, and every four hours up to 24 hours postoperatively. Statistical analysis utilized one-way analysis of variance (ANOVA). Results Group B (levobupivacaine with midazolam) exhibited a shorter time to sensory block onset (88 seconds) compared to Groups A and C (both 145 seconds) (p < 0.001). Group A (levobupivacaine with fentanyl) showed a shorter time to maximum motor block (p = 0.045) than Groups B and C. The sensory block duration was significantly longer in Group A (127.5 minutes) compared to Group B (60 minutes) and Group C (69 minutes) (p < 0.001). Motor block duration was also prolonged in Group A (251 minutes) compared to Group B (147 minutes) and Group C (177 minutes) (p = 0.045). The first analgesic requirement was delayed in Group A (248 minutes), whereas Groups B (115 minutes) and C (90 minutes) (p < 0.001) required more frequent analgesia. Group A experienced a higher incidence of postoperative nausea and vomiting. Conclusion Midazolam accelerated sensory block onset, while fentanyl prolonged anesthesia duration without significantly affecting motor block. Fentanyl delayed the first analgesic requirement, whereas midazolam reduced postoperative nausea, vomiting, and shivering.

Intravenous Dexamethasone versus intrathecal Dexamethasone in Prolonging the Duration of Spinal Anesthesia and Postoperative Analgesia in Elective Cesarean Section

Abstract Background Spinal anesthesia is the most commonly used technique for cesarean section as it is very economical and easy to administer. The short duration of action of local anesthetic drugs has created a matter of concern for anesthesiologists. Aim of the Work To compare the efficacy of intrathecal dexamethasone with intravenous dexamethasone as an adjuvant to prolong the sensory block obtained by spinal anesthesia and postoperative analgesia in cesarean section. Participants and Methods 66 pregnant women scheduled for cesarean section were randomly allocated to one of three groups including (22) patients each. All the patients received injection of heavy bupivacaine 0.5% 10 mg through spinal anesthesia, with adding 1 mL of 0.9% saline and normal saline 2 mL intravenously (control group), or 0.5 mL (2mg) dexamethasone diluted in 0.5 ml of 0.9% saline intrathecally with normal saline 2 mL intravenously (IT group ), or dexamethasone 2 mL (8mg) intravenously with intrathecal injection of heavy bupivacaine 0.5% 2 mL plus 1 mL of 0.9% saline (IV group ) with overall 3 ml volume intrathecally in each group. Duration of sensory block, postoperative analgesia, visual analog pain scale (VAS) score, time of rescue analgesia in the first 24 h, intra- and post-operative hemodynamics, and side effects if any were recorded. Results The study groups, There was significantly higher post-operative analgesic duration (8.73 ± 2.64) hours compared to addition of Intravenous Dexamethasone (4.91 ± 1.02) hours or using hyperbaric bupivacaine alone (3.43 ± 0.71) hours with p-value &amp;lt;0.001. There was no effect on the time of onset of sensory block with no significant complications were detected. Conclusion The addition of 2mg dexamethasone intrathecally as an adjuvant to spinal anesthesia during cesarean section prolong the duration of sensory block and postoperative analgesia.

Norepinephrine versus Ephedrine in Prevention of Hypotension after Spinal Anesthesia in Cesarean Section

Abstract Background Spinal anesthesia is the preferred anesthetic method for elective cesarean section in obstetric anesthesia practice. Cesarean sections normally require an anesthetic block at T4 level, so hypotension is reported in up to 80% of spinal anesthesia cases. Aim of the Work This study aims to compare norepinephrine versus ephedrine in Prevention of hypotension in CS under spinal anesthesia. Patients and Methods The study was a clinical Prospective, double–blinded and randomized study, the operating theatres of Ain Shams University Hospitals over one year. Results We administered the vasopressors by iv infusion when SBP drops 20% below the baseline. We found that no significant difference between both groups regarding fetal Apgar score. We compared two different vasopressors and we chose the regimen of iv infusion. Conclusion We found lower numbers of hypotension and hypertension episodes and less frequency of bradycardia and tachycardia in the patients treated with norepinephrine.

Comparison of intravenous bolus phenylephrine, ephedrine and mephentermine for maintenance of arterial blood pressure during spinal anaesthesia in caesarean section

Background: Subarachnoid block, although being highly efficient, often has limitation such as hypotension which can result in adverse maternal and fetal outcome, continues to be a matter of concern to the Anesthesiologist. The study was to compare the effect of phenylephrine, ephedrine and mephentermine, for maintenance of arterial pressure during spinal anaesthesia for caesarean section. Methodology: A prospective randomized double blinded study involving 90 patients with hypotension after subarachnoid block under spinal anesthesia was conducted, dividing them into three groups: P (Phenylephrine) 100 mcg, E (Ephedrine) 6 mg, and M (Mephentermine) 6 mg. Patients were compared based on age, weight, height, hemodynamic parameters, complications, and neonatal APGAR scores. Results: On inter-group comparison rise in systolic, diastolic and mean arterial blood pressure at 1,2,4 and 6min after drug administration were significantly high in phenylephrine group (p &lt;0.01) compared to ephedrine and mephentermine group. Thereafter the differences narrowed off. Heart rate was raised during episodes of hypotension. The mean heart rate was decreased significantly (p&lt;0.05) in phenylephrine group compared to other two groups. The neonatal APGAR score were &gt;/= 7 in the three groups at the 1st and 5th min. Conclusion: The study found that phenylephrine, ephedrine, and mephentermine effectively maintained arterial blood pressure in intravenous bolus form during subarachnoid block for caesarean section. Phenylephrine, a fast-acting, short-lived normotensive drug, significantly reduced heart rate compared to ephedrine and mephentermine, but did not cause significant adverse effects on mother and fetus.

Posterior Reversible Encephalopathy Syndrome After Inadvertent Dural Puncture Vs Bupivacaine-Induced Adverse Drug Reaction: A Case Report

A case involving a 29-year-old female patient with a known case of hypothyroidism at 38 weeks gestation. She developed a fronto-occipital, postural type of headache. This ensued on the second postoperative day after undergoing an unintended dural puncture with the introducer needle during spinal anesthesia for an elective cesarean section. It was initially treated as a post-dural puncture headache until she developed generalized tonic–clonic seizures the next day. Magnetic resonance imaging (MRI) of the brain exhibited features of posterior reversible encephalopathy syndrome (PRES). With anticonvulsants and antibiotics, the neurological symptoms subsided, and the patient was discharged home symptom-free. We call attention to the importance of suspecting PRES in obstetric cases with an inadvertent dural puncture in a normotensive patient. Neuroimaging plays a crucial role in making a diagnosis of headaches, especially during the peripartum period. Lastly, keeping in view, the potential medicolegal implications in such cases, further research seems vital, especially in the Asian population.

Continuous Spinal Anesthesia for Cesarean Section in a Parturient with Peripartum Cardiomyopathy

Height Adjusted Dose versus Height-Weight Adjusted Dose of Intrathecal Hyperbaric Bupivacaine for Caesarean Delivery for Preventing Maternal Hypotension: A Prospective, Double-Blinded, Randomized Controlled Study

Background: Spinal anesthesia for cesarean section is associated with significant hypotension due to sympathetic blockade and can cause adverse maternal and fetal outcomes. Although hypotension is considered to be dose-dependent, choosing a dose of bupivacaine to achieve an adequate level of blockade without causing hypotension is a challenge. Methods: Ninety-six eligible parturients posted for elective cesarean section under spinal anesthesia were divided into two groups. Group H received intrathecal bupivacaine dose calculated as per patients’ height and Group HW received intrathecal bupivacaine dose calculated as per patients’ height and weight chart. Heart rate and mean blood pressure were monitored in both groups. Time required to achieve sensory block up to T6, complete motor block, the dose of ephedrine required to treat hypotension, the incidence of complications, and neonatal appearance, pulse, grimace, activity, respiration (APGAR) scores were noted. Results: Hypotension occurred in 35.56% of parturients in Group H and 16.28% of parturients in Group HW, which was statistically significant. The mean dose of 0.5% bupivacaine was 9.12 mg in Group HW and 9.4 mg in Group H (P value = 0.02). The mean dose of Ephedrine was 12 ± 5.8 mg in Group H compared to 6.0 mg in Group HW, which was statistically significant. The time needed to achieve sensory and complete motor block were comparable in both groups. Conclusion: Height-weight-adjusted intrathecal hyperbaric bupivacaine achieved comparable sensory and motor block with lesser incidence and severity of hypotension compared to height-adjusted dose.

Comparison of Prophylactic Phenylephrine Infusion and Rescue Bolus Administration for Maintaining Blood Pressure During Spinal Anaesthesia for Caesarean Delivery in Obese Parturient: A Randomised Control Trial.

Phenylephrine (PE) is one of the vasopressor used to treat hypotension during anaesthesia. The primary aim of this study was to compare the effect of prophylactic infusion and rescue bolus of PE on the haemodynamic changes during spinal anaesthesia (SA) for Caesarean section (CS) in obese parturients. A total of 74 obese parturients scheduled for elective CS under SA were randomised into two groups; Group A (n = 37) received prophylactic PE infusion starting at 50 μg min-1 and adjusted according to the given algorithm and Group B (n = 37) received 100 μg PE bolus to treat hypotension. The measured parameters were systolic blood pressure (SBP), diastolic blood pressure (DBP), mean arterial pressure (MAP), the total requirement of PE and neonatal Apgar score. Six patients were excluded from the analysis due to missing data and only 68 were analysed. Group A showed significantly higher SBP, DBP and MAP than Group B (P < 0.05). The requirement of PE was higher in Group A than Group B [817.7 (265.7) μg versus 360.6 (156.0) μg; P = < 0.05]. Both groups had no difference in terms of the neonatal Apgar score. Prophylactic PE infusion provided better haemodynamic control than therapeutic boluses in obese parturients undergoing CS under SA.

Effect of intravenous palonosetron on hypotension induced by spinal anesthesia for cesarean section: A randomized controlled trial.

The aim of this study was to evaluate the impact of intravenous palonosetron compared to ondansetron on hypotension induced by spinal anesthesia in women undergoing cesarean section. Fifty-four women scheduled for elective cesarean section were, randomly allocated to ondansetron group (n = 27) or palonosetron group (n = 27). Ten minutes prior to the administration of spinal anesthesia, participants received an intravenous injection of either ondansetron or palonosetron. A prophylactic phenylephrine infusion was initiated immediately following the intrathecal administration of bupivacaine and fentanyl. The infusion rate was titrated to maintain adequate blood pressure until the time of fetal delivery. The primary outcome was total dose of phenylephrine administered. The secondary outcomes were nausea or vomiting, the need for rescue antiemetics, hypotension, bradycardia, and shivering. Complete response rate, defined as the absence of postoperative nausea and vomiting and no need for additional antiemetics, were assessed for up to 24 hours post-surgery. No significant differences were observed in the total dose of phenylephrine used between the ondansetron and palonosetron groups (387.5 μg [interquartile range, 291.3-507.8 μg versus 428.0 μg [interquartile range, 305.0-507.0 μg], P = 0.42). Complete response rates also showed no significant differences between the groups both within two hours post-spinal anesthesia (88.9% in the ondansetron group versus 100% in the palonosetron group; P = 0.24) and at 24 hours post-surgery (81.5% in the ondansetron group versus 88.8% in the palonosetron group; P = 0.7). In addition, there was no difference in other secondary outcomes. Prophylactic administration of palonosetron did not demonstrate a superior effect over ondansetron in mitigating hemodynamic changes or reducing phenylephrine requirements in patients undergoing spinal anesthesia with bupivacaine and fentanyl for cesarean section.

Comparative Effects of Target-Controlled Infusion of Propofol Versus Spinal and Thiopental-Sevoflurane Anesthesia on Lipid Peroxidation in Elective Cesarean Section: A Prospective, Open-Label Study.

During pregnancy, physiological changes can increase oxidative stress (OS) in both mothers and fetuses. The use of anesthesia for cesarean sections (CSs) could exacerbate this stress due to its impact on the ischemia-reperfusion effect. Our study aimed to explore the effects of target-controlled infusion of propofol on OS during CSs, and to compare these effects with those of spinal and thiopental-sevoflurane anesthesia. The study included ninety parturients undergoing elective CS, allocated into three groups: Group S (spinal) (n = 30), Group P (propofol) (n = 30), and Group TS (thiopental-sevoflurane) (n = 30). Venous blood samples were taken from mothers at three time points, before, during, and after surgery, and one sample was taken from the umbilical vein after delivery. Blood samples were analyzed with the thiobarbituric acid reactive substances (TBARS) assay and blood gas analysis. A statistical comparison between groups was obtained by one-way analysis of variance (ANOVA) and the Wilcoxon test where appropriate. Levels of TBARS after the induction of anesthesia were lower in all groups compared to values preoperatively. In Group P, TBARS levels started to decrease in the first five minutes after the induction (1.90 ± 0.47; P < 0.001) and had significantly lower values compared to Group S (2.22 ± 0.21) and Group TS (2.40 ± 0.20). Two hours after surgery, TBARS values were the lowest in Group P (1.76 ± 0.15, P<0.001), compared to Group S (2.18 ± 0.24) and Group TS (2.41 ± 0.21). TBARS value in umbilical venous blood was significantly lower in Group P (1.56 ± 0.16, P < 0.001) compared to Group S (2.18 ± 0.17) and Group TS (2.09 ± 0.09). Umbilical cord venous blood gas values (pH, PCO2, HCO3, lactates, and base excess (BE)) were not different between the groups, except for PO2, which was significantly lower in Group S (20.5 ± 5.0; P < 0.001) compared to Group P (36.5 ± 19.2) and Group TS (33.5 ± 10.1). Target-controlled infusion of propofol anesthesia could beadvantageous for parturients with compromised oxidative status, especially those undergoing emergency CSs when general anesthesia is required.

Correlation between peripheral perfusion index and total vasopressor dose, nausea/ vomiting, and uterine contraction after spinal anesthesia in cesarean section: A correlative cross-sectional observational study

Background and AimsHypotension and other complications following spinal anaesthesia, such as nausea, vomiting, and poor uterine contractions during caesarean section, are common. There is no tool to predict the possibility of hypotension, nausea and vomiting, and poor uterine contractions to make proper anticipations. Peripheral Perfusion Index (PPI) is a noninvasive monitoring tool using an oximeter and can be used to indicate a patient's Systemic Vascular Resistance (SVR). This study aimed to find the correlation between pre-anaesthesia PPI and total vasopressor administration, nausea and vomiting, and uterine contraction using Linear Analogue Scale (LAS) after spinal anaesthesia for caesarean section. MethodsThe research subjects were 65 pregnant patients with the American Society of anaesthesiology II (ASA II) who underwent caesarean section at Hasan Sadikin General Hospital, Bandung, from November 2022 to April 2023. PPI was measured before spinal anaesthesia, and monitoring of nausea and vomiting, vasopressor administration, and LAS was performed intraoperatively. ResultsThe results of this study showed that PPI had a strong positive correlation (r = 0.795) with total vasopressor administration, a moderate positive correlation (r = 0.506) with nausea and vomiting, and a moderate negative correlation (r = 0.574) with LAS. The AUC analysis revealed an excellent hypotension prediction with a cut-off value of 3.5 (AUC 0.868; CI 95%). ConclusionWe conclude that PPI can be used as a predictor of vasopressor administration, nausea and vomiting, and uterine contractions.

Pregnancy complicated by severe osteogenesis imperfecta poses a challenge for the anaesthetist: A case report.

Pregnant women with severe osteogenesis imperfecta (OI) are uncommon, and there are limited data regarding anaesthesia for caesarean section in these high-risk individuals. The presence of anatomical and physiological abnormalities can pose technical challenges for the anaesthetist. This report describes the successful implementation of epidural anaesthesia in a parturient with severe OI. To our knowledge, this is the first documented use of ultrasound-assisted neuraxial anaesthesia and wrist blood pressure monitoring in such patients undergoing caesarean section. Understanding the pathophysiological changes associated with OI is crucial for ensuring safe administration of anaesthesia to these women.

Changes in Compression Pressure of Elastic Stockings for the Lower Limbs During Cesarean Section: A Prospective Observational Study.

Background Postpartum peripheral nerve injuries can impact recovery. Elastic stockings are recommended for thromboembolism prevention, although concerns about entrapment neuropathy exist. In this prospective observational study, we investigated the differential compressions caused by wearing elastic stockings before and after anesthesia, as well as changes in the diameters of the lower leg and ankle in parturient women undergoing spinal anesthesia for elective cesarean section (CS). Methods Eighteen pregnant women, classified by the American Society of Anesthesiologists as having physical status 2, underwent lower leg measurements taken before a CS. Elastic stockings were applied, and compression pressure was measured at pre-anesthesia, post-surgery, and six hours post-return to a hospital room. Fluid, blood loss, urine output, and neuropathy presence were recorded. For all parameters, changes at the three time points were compared for the primary analysis. For secondary analysis, participants were categorized as having intraoperative blood loss greater than (group P) or less than 1,000 g (group N), and factors were compared with pre-anesthesia and six hours post-return to a room. Data were analyzed and presented using a one-way analysis of variance with Bonferroni correction for multiple comparisons or unpaired two-tailed t-tests for pairwise comparison. Results None of the women had postoperative entrapment neuropathy. Six patients had >1,000 g of blood loss. Compression significantly increased from pre-anesthesia (left 13.6 ± 2.4, 95% CI: 12.18 to 14.52; right 13.4 ± 2.4, 95% CI: 12.41 to 14.69) to post-surgery (left, 17.4 ± 2.6, 95% CI: 15.68 to 18.12; right, 16.9 ± 2.6, 95% CI: 16.20 to 18.70) (p < 0.01). Compression pressure at post-surgery differed significantly between group P (left, 15.3 ± 1.3; right, 14.7 ± 1.8; 95% CI: -4.98 to -0.32) and group N (left, 18.1 ± 2.9; right, 17.8 ± 2.4; 95% CI: -5.38 to -0.26) (p < 0.05). The results are expressed as mean ± standard deviation, with P-values <0.05 indicating statistical significance. Conclusions In this study, no neuropathy occurred; however, over-compression risk with elastic stockings, especially when exceeding recommended pressure levels, was highlighted. Balancing thromboembolism prevention and over-compression risks is crucial for patients undergoing CSs with spinal anesthesia.
