Analgesic effect of ultrasound-guided erector spinae plane block (espb) in general anesthesia for cesarean section: a randomized controlled trial

BackgroundThe analgesic effects of erector spinae plane block in general anesthesia for cesarean section and recovery from puerperae remain unclear.MethodsSixty patients with contraindications for spinal anesthesia who required general anesthesia for cesarean section were enrolled and randomly divided into the erector spinal plane block (ESPB) combined with the general anesthesia group (group E) and general anesthesia group (group G). Group E received bilateral ESPB (20 ml of 0.25% ropivacaine on each side) under ultrasound guidance 30 min before general anesthesia. The primary outcomes were the number of patient-controlled intravenous analgesia (PCIA) boluses, and Bruggemann comfort scale (BCS) scores at 2 h, 6 h, 12 h, and 24 h after operation. The second outcome was intraoperative anesthesia dosage, fetal delivery time, puerperae emergence time, visual analog scale (VAS) at 2 h, 6 h, 12 h, and 24 h after operation, and incidence of nausea and vomiting. Heart rate (HR) and mean arterial pressure (MAP) were recorded 10 min before the start of anesthesia (T0), at the induction of anesthesia (T1), at skin incision (T2), and fetal delivery (T3), and immediately after surgery (T4).ResultsThe number of PCIA boluses was lower in group E than in group G (P < 0.001). The BCS score increased at 2 h and 6 h after the operation in group E (P < 0.05), while the VAS score significantly decreased in group E at the same time (P < 0.05). Compared with group G, the doses of propofol and remifentanil were significantly decreased in group E (P < 0.001), the emergence time of puerperae was shortened (P = 0.003), and the incidence of nausea and vomiting was significantly decreased (P = 0.014).ConclusionUltrasound-guided ESPB applied to general anesthesia for a cesarean section can significantly reduce the required dose of general anesthetic drugs, shorten the recovery time of the puerperae, and improve postoperative analgesia.Trial registration:www.clinicaltrials.gov under the number ChiCTR2200056337 (04–02-2022).

The Use of Non-Invasive Continuous Blood Pressure Measuring (ClearSight®) during Central Neuraxial Anaesthesia for Caesarean Section—A Retrospective Validation Study

: BackgroundThe close monitoring of blood pressure during a caesarean section performed under central neuraxial anaesthesia should be the standard of safe anaesthesia. As classical oscillometric and invasive blood pressure measuring have intrinsic disadvantages, we investigated a novel, non-invasive technique for continuous blood pressure measuring. Methods: In this monocentric, retrospective data analysis, the reliability of continuous non-invasive blood pressure measuring using ClearSight® (Edwards Lifesciences Corporation) is validated in 31 women undergoing central neuraxial anaesthesia for caesarean section. In addition, patients and professionals evaluated ClearSight® through questioning. Results: 139 measurements from 11 patients were included in the final analysis. Employing Bland–Altman analyses, we identified a bias of −10.8 mmHg for systolic, of −0.45 mmHg for diastolic and of +0.68 mmHg for mean arterial blood pressure measurements. Pooling all paired measurements resulted in a Pearson correlation coefficient of 0.7 for systolic, of 0.67 for diastolic and of 0.75 for mean arterial blood pressure. Compensating the interindividual differences in linear regressions of the paired measurements provided improved correlation coefficients of 0.73 for systolic, of 0.9 for diastolic and of 0.89 for mean arterial blood pressure measurements. Discussion: Diastolic and mean arterial blood pressure are within an acceptable range of deviation from the reference method, according to the Association for the Advancement of Medical Instrumentation (AAMI) in the patient collective under study. Both patients and professionals prefer ClearSight® to oscillometric blood pressure measurement in regard of comfort and handling.

General anesthesia for cesarean section: are we doing it well?

Korea has a higher rate of cesarean sections under general anesthesia than in other countries. Neuraxial anesthesia is the gold standard for a cesarean section, but there are some cases in which general anesthesia is inevitable. Therefore, obstetric anesthesiologists should be familiar in performing general anesthesia for cesarean section. Rapid-sequence induction and intubation with cricoid pressure using thiopental-succinylcholine have been the standard for cesarean section under general anesthesia for a long time. Recently, with the introduction of new drugs (propofol, rocuronium, and sugammadex) and equipments (videolaryngoscopy and supraglottic airways), anesthesia methods have also gradually changed. Pursuing the safety of obstetric patients and anesthesiologists at the same time, this review will help update the knowledge or training in performing general anesthesia for cesarean section.

Psychosomatic Strange Reactions in Pregnant Women Following Spinal Anesthesia for Cesarean Section

Psychosomatic Strange Reactions in Pregnant Women Following Spinal Anesthesia for Cesarean Section

Hemodynamic and analgesic effect of intrathecal fentanyl with bupivacaine in patients undergoing elective cesarean section; a prospective cohort study.

BackgroundSpinal anesthesia with bupivacaine has side effects such as hypotension, respiratory depression, vomiting, and shivering. The side effects are dose-dependent, therefore different approaches have been attempted to avoid spinal-induced complications including lowering the dose of local anesthetic and mixing it with additives like Neuraxial opioids.ObjectiveTo compare the Hemodynamic and analgesic effects of intrathecal fentanyl as an adjuvant with low and conventional doses of bupivacaine in patients undergoing elective cesarean section under spinal anesthesia.MethodologyAn institutional-based prospective cohort study was conducted on 90 patients. Data was collected with chart review, intraoperative observation, and postoperatively patient interview. Data was entered into EPI INFO and transport to SPSS version 23 for analysis of variables using one-way ANOVA, Kruskal Wallis H rank test, and chi-square.ResultHypotension but not bradycardia, was significantly frequent in a conventional dose of bupivacaine alone (CB) group and a conventional dose of bupivacaine with fentanyl (CBF) groups than that of the lower dose of bupivacaine with fentanyl (LBF) groups. Duration of analgesia was significantly longer in LBF (248± 35.6 minutes) and in CBF groups (260.3±40.3 minutes) than in CB group (167.10 ± 31.45 minutes). Time for the first analgesic request was significantly later in LBF (304±47.8 minutes) and CBF (294.6±99.5 minutes) groups than that in CB group (177±25.88 minutes).ConclusionThe Lower dose of bupivacaine is associated with less risk of hypotension and faster recovery. Adding fentanyl with the lower dose of bupivacaine in spinal anesthesia for cesarean section could provide comparable anesthesia with the lower risk of hypotension and longer postoperative analgesia.

Accuracy of Spinal Anesthesia Drug Concentrations in Mixtures Prepared by Anesthetists.

Medication errors include the indirect dosing of drugs. For spinal anesthesia mixtures of local anesthetics, opioids are drawn from ampoules and combined in a syringe, according to clinical practice. We set out to determine the accuracy of the drug mixtures. Physicians of our department were invited to prepare the mixture used for spinal anesthesia for cesarean section, consisting of 10-mg hyperbaric bupivacaine (2-mL volume), 20-μg fentanyl (0.4-mL volume), and 100-μg morphine (0.1-mL volume). Concentrations of these drugs were determined by means of high performance liquid chromatography. Interindividual and intraindividual variations were assessed. We analyzed 96 samples from 31 physicians. Fifty-one percent of the measured bupivacaine concentrations were in ±10% deviation range of the intended concentration; 17% of the fentanyl and 24% of the morphine concentrations were in this range. A total of 2.1% of the samples had a bupivacaine concentration corresponding to a dose of 8 mg or less, and 11.5% of the samples had a morphine concentration corresponding to a dose of 150 μg or greater. Intraindividual variations were 10.9% for bupivacaine, 24.7% for fentanyl, and 38.9% for morphine. Our results show a high deviation of the obtained from the intended concentrations. Two percent of the samples had bupivacaine concentrations that probably resulted into an insufficient analgesia, and 11% of the samples had morphine concentrations that, according to guidelines, would require a longer monitoring period than with the intended dose.

Evaluation of Hemodynamic changes in Elective Cesarean section under Spinal Anesthesia

Background: Spinal block provides excellent anesthesia for cesarean section, but it is frequently accompanied byhypotension, which if untreated can pose serious risks to mother and baby. Over the years, many interventions have beentried to prevent hypotension, but no single technique has proven to be effective and reliable. This study was carried outwith the aim to find if wrapping the legs with elastic crepe bandage in addition to traditional methods was effective inpreventing post spinal hypotension.Materials and Methods: A total of 60 full-term parturients with an uncomplicated pregnancy belonging to AmericanSociety of Anesthesiologists I or II were allocated randomly (30 in each group) to have their legs wrapped with elasticcrepe bandage or no wrapping was done. All patients received intravenous (IV) crystalloid (20 ml/kg) 15 min priorto spinal injection and were placed in left lateral position. Electrocardiography and oxygen saturation was monitoredcontinuously and heart rate, blood pressure was measured every 2 min until delivery of baby and every 5 min thereafteruntil end of cesarean section. Significant hypotension was treated with IV phenylephrine 50 μg bolus doses.Results: The frequency of hypotension was significantly less (P = 0.009) in Group B (legs wrapped group) 3 (10%) patientswhen compared with Group A (nonleg wrapped) 13 (43.33%). In Group A 10 (33.33%) patients and in Group B 3 (10%)patients required rescue dose with phenylephrine which was statistically significant (P = 0.0003). Difference in the “meanchange of arterial pressure” between Group A and B was highly significant (P &lt; 0.001) recorded at 4, 6, and 8 min.Conclusion: Incidence of hypotension can be reduced by wrapping the legs with elastic crepe bandage with a subsequentreduction in the use of potent vasopressor. Since leg wrapping with crepe bandage is cheap, easy, readily available,noninvasive, and nonpharmacological method, it can be recommended for preventing post spinal hypotension in adeveloping country like ours.

Pituitary Apoplexy and Subdural Hematoma after Caesarean Section

Pituitary apoplexy can occur postpartum, and subdural hematoma following epidural anesthesia is a rare complication. Cooccurrence of these two complications is extremely rare and has not been previously reported in the literature. In this article, we present a case of pituitary apoplexy along with intracranial subdural hematoma happening two days after spinal anesthesia for cesarean section. The patient presented with peripheral facial nerve paralysis accompanied by headache, eye pain, and blurred vision and was diagnosed by imaging modalities. The patient made a good recovery with conservative treatment without serious health events.

Association of General Anesthesia and Neuraxial Anesthesia in Caesarean Section with Maternal Postpartum Depression: A Retrospective Nationwide Population-Based Cohort Study

Although cesarean section (CS) has become a common method of child delivery in recent decades, the choice between general anesthesia (GA) and neuraxial anesthesia (NA) for CS must be carefully considered. Depending on the type of anesthesia used in CS, a major outcome observed is the occurrence of postpartum depression (PPD). This study investigated the association between PPD risk and the anesthesia method used in CS by using data from three linked nationwide databases in Taiwan, namely, the National Health Insurance Research Database, the National Birth Reporting Database, and the National Death Index Database. After propensity score matching by baseline depressive disorders, maternal demographics, status at delivery, infant’s health, maternal diseases during pregnancy, and age of partner, we included women who had natural births (n = 15,706), cesarean sections with GA (n = 15,706), and cesarean sections with NA (n = 15,706). A conditional logistic regression was used to estimate the odds ratios and 95% confidence intervals (CIs) of PPDs, including depression, sleep disorder, and medication with hypnotics or antidepressants, under anesthesia during CS. The prevalence rates of combined PPDs were 26.66%, 43.87%, and 36.30% in natural births, CS with GA, and CS with NA, respectively. In particular, the proportions of postpartum use of hypnotic drugs or antidepressants were 21.70%, 39.77%, and 31.84%, which were significantly different. The aORs (95% CIs) were 2.15 (2.05–2.25) for the included depressive disorders, 1.10 (1.00–1.21) for depression, 1.03 (0.96–1.11) for sleep disorder, and 2.38 (2.27–2.50) for medication with hypnotics or antidepressants in CS with GA compared with natural births. Women who underwent CS with GA had a significantly higher risk of depressive disorders and a higher need for antidepressants for sleep problems than those who underwent CS with NA. The risks of PPD were significantly associated with the anesthesia method, especially GA. Our results can assist physicians in carefully considering the appropriate anesthesia method for CS delivery, particularly with regard to postpartum drug abuse and drug safety.

Tramadol vs. pethidine to control perioperative shivering in cesarean section under spinal anesthesia: a double-blind study

Background &amp; objective: Perioperative shivering after spinal anesthesia for cesarean section is a common and unpleasant complication. Currently pethidine is being used but the search continues to look for other agents with faster action and with fewer side effects. Tramadol is a potential anti-shivering drug with modulation of central thermoregulation.&#x0D; We compared the efficacy of tramadol versus pethidine in the treatment of perioperative shivering of patients undergoing cesarean section under spinal anesthesia.&#x0D; Methodology: After institutional ethical review committee approval, 42 patients undergoing cesarean section under spinal anesthesia, who experienced shivering, were randomized into two groups, Group T (n = 21) received 1 mg/kg tramadol and Group P (n = 21) received 0.5 mg/kg pethidine. The outcome measures included the time taken to cessation of shivering after the medication, recurrence of shivering and the incidence of side effects.&#x0D; Results: The parturients with mean age 30.2 ± 5.2 y and body mass index (BMI) 29.9 ± 4.9 kg/m2 were recruited with comparable data between the two groups. Median time taken from drug administration until cessation of shivering of the tramadol group was faster than the pethidine group (7 min vs 13 min, P = 0.049). However, there was no significant difference in terms of the number of recurrences of shivering (P = 0.606) and incidence of nausea (P = 0.19) between the two groups.&#x0D; Conclusion: Intravenous tramadol has faster alleviation of perioperative shivering than intravenous pethidine in the treatment of perioperative shivering.&#x0D; Key word: Tramadol; Pethidine; Cesarean section; Shivering; Anesthesia, Spinal&#x0D; Citation: Yaakop AF, Hassan MH, Omar SC, Mazlan MZ, Mukmin LA, Hassan WNW.

A Height-Based Dosing Algorithm of Bupivacaine in Spinal Anesthesia for Decreasing Maternal Hypotension in Cesarean Section Without Prophylactic Fluid Preloading and Vasopressors: A Randomized-Controlled Non-Inferiority Trial.

BackgroundThere is a high incidence of maternal hypotension in spinal anesthesia for cesarean section. The aim of the study is to investigate whether there is a height-based dosing algorithm of bupivacaine that provides adequate anesthesia with less maternal hypotension.MethodsThere were 2 groups of 280 parturients who did not receive prophylactic fluid preloading: Test and Conventional group. In Test group, a height based dosing algorithm was used to confirm the dose of bupivacaine in parturients without prophylactic vasopressors. In the Conventional group, a constant dose of bupivacaine was used. The complications and quality of anesthesia were evaluated.ResultsIn the Conventional group, the shorter participants had higher incidence of hypotension, faster sensory block time, and more participants with complete motor block (p = 0.030, 2.957 × 10−14, and 0.012). In the Test group, the incidence of hypotension, sensory block time, and number of participants with complete motor block did not change with height (p = 0.199, 0.617, and 0.209). The height-based dosing algorithm of bupivacaine decreased the incidence of hypotension (p = 0.004), induced lower sensory block level and less degree of motor block (p = 3.513 × 10−7 and 5.711 × 10−11). The quality of analgesia, quality of muscle relaxation, and degree of intraoperative comfort were similar in both groups (p = 0.065, 0.498, and 0.483).ConclusionsThe height influences the dose of bupivacaine in spinal anesthesia; without prophylactic fluid pre-loading and vasopressors, the height-based dosing algorithm of bupivacaine is suitable, and meets the cesarean section' requirement with less maternal hypotension.Clinical Trial Registrationwww.ClinicalTrials.gov, identifier: NCT03497364.

COMPARISON OF TWO DIFFERENT DOSAGES OF COMBINATION OF INTRAVENOUS GRANISETRON WITH INTRAVENOUS DEXAMETHASONE AS A PROPHYLAXIS FOR NAUSEA AND VOMITING IN CAESAREAN SECTION WITH SUBARACHNOID BLOCK

Granisetron can be used to treat and prevent nausea and vomiting in patients receiving chemotherapy or radiotherapy, as well as during or after surgery. To compare the effects of two doses of intravenous granisetron on nausea and vomiting in Caesarean section with subarachnoid block. This study was a randomized double-blind clinical trial. Subjects were randomized into two groups: Granisetron 10 mcg/kg (GD10) and granisetron 25 mcg/kg (GD25). Dexamethasone 0.1 mg/kg was also administered to all subjects. A total of 21 subjects were included for each group. Data was analyzed using Mann Whitney U test. The results When comparing the incidence of nausea and vomiting in the GD10 and GD25 groups, there was a significant difference in the incidence of nausea (p = 0.001). In the GD10 group, there were nine participants who experienced nausea, whereas the GD25 group had none. Neither of the groups experienced vomiting, hence no additional therapy given to both groups. Granisetron is a selective 5-HT3 receptor antagonist and an effective antiemetic during and after neuraxial anesthesia for Caesarean section. The combination of granisetron and dexamethasone has been reported to be more potent than granisetron alone. Administration of granisetron 25 mcg/kg had a positive impact on patients, with no incidence of nausea and vomiting compared to administration of granisetron 10 mcg/kg.

Effect of Intravenous Calcium Gluconate on Prevention of Post Spinal Hypotension during Spinal Anaesthesia for Caesarean Section: A Randomized Double-Blind Controlled Study.

Calcium, a physiological ion, causes vasoconstriction and has a positive ionotropic action on heart. Its use to prevent post-spinal hypotension has been suggested but never formally evaluated for patients undergoing caesarean section. This study investigated the hemodynamic effects of calcium administration in parturients with the primary aim of comparing the incidence of post-spinal hypotension. Sixty healthy full-term pregnant patients scheduled for caesarean section were randomly allocated to two equal groups to receive either calcium gluconate or normal Saline bolus over 20min by syringe infusion pump under electrocardiography monitoring immediately after the patient was turned supine following spinal anaesthesia. Blood pressure and heart rate were recorded at baseline, and at regular intervals following spinal. Maternal calcium levels were estimated before and after infusion. Neonatal blood gas analysis and calcium level were analyzed. Total mephentermine requirement was recorded in both groups. The heart rate values remained comparable to baseline value in group calcium gluconate while in group normal Saline, it decreased significantly at 8,12 and 16min. Blood pressure decreased significantly as compared to the baseline value from 4min onwards in both the groups. However, it was comparable in the two groups at all time points(0.622). Nineteen patients(63.33%) required mephentermine infusion in group calcium gluconate as compared to 23 patients(76.6%) in group normal Saline for maintenance of systolic blood pressure.(p=0.791) Umbilical venous pH (p=0.038) and partial pressure of carbon dioxide(p=0.038) were significantly better in group calcium gluconate. Calcium used for prophylaxis of hypotension in healthy parturients undergoing caesarean section reduced the vasopressor requirements and total mephenteramine dose, but the difference did not attain statistical significance.

P08 The difficulty of Pseudomonas aeruginosa eradication in a post-spinal anaesthesia meningitis

BackgroundMeningitis and ventriculitis due to Pseudomonas aeruginosa are uncommon. They are commonly secondary hospital-onset and typically related to neurosurgical procedure. Previous studies have shown P. aeruginosa to be responsible for 1%–18% of nosocomial meningitis cases. Both treatment failure and relapses are known to occur, and the recorded mortality is high, approaching 80% in some studies.ObjectivesWe report a case of P. aeruginosa meningitis in a 26-year-old woman following spinal anaesthesia for caesarean section, its clinical characteristics, treatment challenges in the era of high generation antibiotics and the outcomes.ResultsA 26-year-old woman was hospitalized after 1 week of her third child delivery by caesarean section with spinal anaesthesia and 3 days after high fever and headache. Lumbar puncture was performed immediately, and leucocyte cell count was 723 cell/dL with 94% segmented neutrophils. CSF glucose was very low, and protein was 420 mg/dL. P. aeruginosa was isolated and it was susceptible to all antibiotics of standard panel. Cranial and lumbar region CT scans were normal. We modified empirical treatment and started ceftazidime and gentamicin. Three days after de-hospitalization in improved condition, she had high fever and strong headache and came back to hospital. We started treatment with imipenem and ciprofloxacin and 2 months after we performed several lumbar punctures, cranial MRIs and changed different antibiotic regimens with third generation cephalosporins, aminoglycosides, carbapenems and colistin; her clinical situation such as headache and fever and CSF did not show any sign of improvement. Susceptible P. aeruginosa was isolated each time we examined her CSF. She decided to leave the hospital and 2 weeks after her headache worsened and a convulsive attack happened. The cranial MRI showed hydrocephaly and a white precipitate (pus) in the left lateral ventricle. An extraventricular drain helped to resolve hydrocephaly and intraventricular colistin was injected until CSF was sterilized. After 1 month she was in a very good condition and a ventriculo-peritoneal shunt was placed.Conclusions P. aeruginosa meningitis was associated with some treatment difficulties. Even after an early nosological and microbiological diagnosis and an appropriate choice of antibiotics, based on bacterial meningitis treatment criteria and antibiogram, we couldn't eradicate the bacteria from CSF. To achieve success in this nosocomial infection from a not careful asepsis, sometimes a prolonged antibiotic and local treatment with intraventricular or intrathecal therapy is needed.

Synergistic effect of inthrathecal fentanyl and bupivacaine in spinal anesthesia for cesarean section in Baghdad city

Background: Potentiating the effect of intrathecal local anesthetics drugs by addition of intrathecal opiods for intra-abdominal surgeries had been used lately. In this study by addition of fentanyl, we tried to minimize the dose of bupivacaine thereby reducing the side effect caused by higher doses of intrathecal bupivacaine in cesarean section, and to improve the quality of block.Methods: Study was performed on sixty patients underwent cesarean section they were divided into 6 groups as B10, B 12.5, B15 mg of bupivacaine and FB10, FB12.5, FB15 received a combination of 25 µg intrathecal fentanyl respectively, the parameter taken into consideration were visceral pain, hemodynamic stability (hypotension and bradycardia) intra operative sedation, nausea, vomiting and post-operative pain. Results: Onset of sensory block to T6 occurred faster with increasing bupivacaine doses in bupivacaine only groups and bupivacaine fentanyl combination groups. Alone lower concentration of bupivacaine could not completely remove the visceral pain. Blood pressure declined with increasing the concentration of bupivacaine and fentanyl. The incidence of nausea and vomiting was reduced significantly while post-operative pain relief and hemodynamics stability increased by adding fentanyl. Pruritis, maternal respiratory depression and changes in APGAR score of babies did not occur with fentanyl. Conclusions: Spinal anesthesia among the neuro axial blocks in obstetric patients’ needs strict dose calculation because minimal dose changes results in more complications and side effects Here the synergistics potentiating effects of fentanyl (an opiod) on bupivicaine (local anesthetic) in spinal anesthesia for cesarean section is presented. Fentanyl is able to reduce a dose of bupivicaine and therefore its harmful effect.

Effect of dexmedetomidine on oxytocin-induced uterine contraction during optimal caesarean section anaesthesia.

Numerous drugs are used during caesarean sections to provide regional and general anaesthesia. Dexmedetomidine has been used in some recent obstetric trials, but there are concerns about postpartum changes in uterine contractions. This study evaluated the effect of dexmedetomidine on oxytocin-induced uterine contractions in women undergoing caesarean section. Sixty women undergoing caesarean section in Lianyungang Second People's Hospital were randomly assigned to dexmedetomidine (group D, n = 30) or saline (group C, n = 30) groups. Equal volumes of saline or dexmedetomidine were administered intravenously (IV). During the intraoperative delivery of the foetus and placenta, oxytocin was administered to promote contractions. Heart rate (HR), systolic blood pressure (SBP), diastolic blood pressure (DBP) and mean arterial pressure (MAP) were compared. The Ramsay scale was used to assess sedation, while the Tsai and Chu methods assessed shivering. Adverse intraoperative events were observed. All variables fluctuated significantly after anaesthesia onset in both groups but were most pronounced in group D. The VAS, Ramsay and shivering scores were significantly lower in group D compared to group C. During rapid IV infusion of oxytocin after foetal delivery, the incidence of nausea, vomiting, chest tightness and hypotension was significantly lower in group D than in group C.

Effect of Cardamom Inhalation Therapy on Intra-and Postoperative Nausea and Vomiting of Mothers Undergoing Spinal Anesthesia for Elective Cesarean Section

This study aimed to determine the effect of cardamom inhalation on intra and postoperative nausea and vomiting (IONV/PONV) of mothers undergoing spinal anesthesia for elective cesarean section. A single-blind, randomized, placebo-controlled clinical trial study. Seventy eligible participates were equally randomized to the intervention or placebo group. The demographic and clinical characteristics questionnaire, a 100 mm Visual Analogue Scale (VAS) to measure the severity of nausea; and the mothers' emetic episodes checklist were used. Upon the first episode of nausea, participants inhaled through a plastic bag containing distilled gauze pads in normal saline with or without Cardamom essential oil. Following the intervention, nausea severity in placebo (25.28 ± 32.38) and cardamom (13.14 ± 19.96) groups declined (P < .001), however after controlling the initial severity of nausea, the declining extent was more noticeable in the intervention group than in the placebo group. The episodes of nausea (37.1% vs 65.7%, P=.006), and retching (20% vs 45.7%, P=.028) were significantly lower in the intervention group than in the placebo group. Administration of antiemetic medications was lower in the intervention than the placebo group (37.1% vs 65.7%, P=.009). Cardamom aromatherapy was effective in alleviating mothers' experience of nausea and retching across the cesarean surgical continuum. As such, it can be considered as a palliative treatment for IONV/PONV in Cesarean section surgeries.

Study of pain scores and need for rescue analgesia with intrathecal fentanyl as an adjuvant with 0.5% hyperbaric bupivacaine for cesarean section

Background: Cesarean section contributes to the major part of surgeries taking place in any hospital now a days. Hence, improving anesthesia in cesarean section is of paramount importance. Intrathecal fentanyl can produce rapid, profound analgesia for cesarean section, early labor with minimal side effects. It also has minimal respiratory depressant effect on fetus. Present study was aimed to study pain scores and need for rescue analgesia with intrathecal fentanyl as an adjuvant with 0.5% hyperbaric bupivacaine for cesarean section. Aims and Objectives: Primary Objective was to evaluate intrathecal fentanyl as an adjuvant with 0.5 % hyperbaric Bupivacaine for caesarean section. The secondary objective was to compare onset and duration of sensory and motor blockade as well as to assess pain scores, analgesic requirements and side effects. Materials and Methods: The present study was hospital-based randomized double-blind control study conducted in pregnant women of 18–35 years age, 50–70 kg weight, ASA-II, posted for elective cesarean section. 60 patients were randomly divided into Group I (study group, n=30, receiving 0.5 % hyperbaric bupivacaine 1.6 ml+intrathecal fentanyl 0.4 ml/20 mcg) and Group II (control group, n=30, receiving 0.5% hyperbaric bupivacaine 1.6 ml+0.4 ml normal saline). Results: The difference in mean time for onset of sensory block, onset of motor block, maximum time taken to achieve highest level of sensory analgesia, total duration of motor block, and degree of motor block was statistically insignificant. The difference in mean duration of time to sensory regression was statistically highly significant (P&lt;0.0001). VAS score was used to assess pain postoperatively initially every 5 min then every 30 min up to 5 h. VAS score in post-operative period was less in Group I and difference was statistically significant. Mean Apgar Score at 1 and 5 min were comparable in both the groups with no statistically significant difference. Diclofenac consumption was significantly decreased in Group I as compared to group II. Conclusion: We conclude that the 0.5% hyperbaric Bupivacaine 8 mg with Fentanyl 20 μg is safe, effective, superior for spinal anesthesia, provided more longer duration of analgesia and significantly reduced number of rescue analgesia doses in cesarean section.

Anaesthesia for caesarean section in a morbidly obese parturient with history of lignocaine allergy: A case report

Morbidly obese obstetric patients present multiple challenges to the anaesthetist for labour analgesia and anaesthesia for caesarean section. The superiority of regional anaesthesia (RA) using local anaesthetics (LA) to all other techniques in the obese parturient, as well as avoiding complications of general anaesthesia (GA) in a caesarean delivery makes LA allergy in parturients an important issue. We report the first known case of lignocaine allergy in a morbidly obese parturient.
