Role of Mifepristone in Induction of Labor in Full-Term Pregnancy.

Objective This study sought to evaluate the safety and efficacy of mifepristone as a uterine sensitizer in shortening induction to delivery time in term pregnancy. Study design A prospective study was carried out on primigravida with a singleton term pregnancy, cephalic presentation, 37 to 41 weeks gestation, Bishop score ≤6, and consented to the study. A total of 116 participants were divided into two groups by random computer-generated sequence. On admission, the Bishop score was assessed. Group A (n=58) received 200 mg of mifepristone. Group B (n=58) received a placebo orally. In both groups, a post-intervention assessment was done after 24 hours, intracervical dinoprostone gel was administered with a maximum of three doses, six hours apart, if the Bishop score was ≤6. The primary outcome was to evaluate the effectiveness of oral mifepristone based on Bishop score improvement, the need for dinoprostone gel, and induction to delivery time. The secondary outcome was to evaluate the safety of oral mifepristone based on cesarean section rate and fetomaternal outcome. Results The Bishop score markedly improved in group A after 24 hours of intervention. A total of 31 women delivered vaginally after receiving only mifepristone. Mean induction to delivery time significantly improved in group A at 23.22±12.57 hours as compared to that in group B at 38.79±7.32 hours. Cesarean delivery rate was lower in group A (27.59%) compared to group B (44.83%). Birth outcomes were consistent in both groups with no neonatal mortality. Conclusion Oral mifepristone has proved as a promising agent as a uterine sensitizer in inducing labor as it has significantly decreased induction to delivery time.

A Comparative Study of Fixed-Dose Dexmedetomidine and Propofol Infusions on Intraoperative Desflurane Consumption During Bispectral Index-Guided Laparoscopic Surgeries: A Randomized Controlled Study.

Background Desflurane is an excellent but expensive volatile anesthetic agent. Dexmedetomidine and propofol may decrease intraoperative desflurane consumption. This study aimed to compare the desflurane-sparing effect of dexmedetomidine and propofol in patients undergoing laparoscopic surgeries under bispectral index (BIS)-guided general anesthesia (GA). Methods Sixty-two adult patients, ASA (American Society of Anesthesiologists) physical status I or II, of either sex, aged between 18 and 60 years, were randomly allocated into group D or group P. Only group D patients received an intravenous (IV) bolus of dexmedetomidine (1 mcg/kg) over 15 minutes before induction. In both groups, GA was induced following the standard protocol with propofol infusion (0.5 mg/kg/min) until the BIS value dropped below 60. For maintenance, group D and group P patients received IV dexmedetomidine infusion (0.5 mcg/kg/h) and propofol infusion (50 mcg/kg/min), respectively. In both groups, desflurane dial concentration was adjusted between 3 and 8% to maintain the BIS within the range of 45-55. An hourly bolus of IV fentanyl (0.5 mcg/kg) and a half-hourly bolus of IV vecuronium (0.02 mg/kg) were administered. The total amount of desflurane consumed, duration of pneumoperitoneum, extra aliquots of propofol used during maintenance, number of boluses of IV atropine, fentanyl, and esmolol, time to attain Ramsay Sedation Score of 2 after extubation, time to first postoperative analgesic request at Numerical Rating Scale (NRS) score ≥ 4, time to reach a Modified Aldrete Score of ≥9, and incidence of any side effects were recorded. All the data were analyzed and compared using appropriate statistical tests, and a p-value of <0.05 was considered significant. Results The final data analysis was performed on 60 patients. The mean desflurane consumption was clinically higher in group P patients than in group D, but the difference was statistically insignificant (p-value > 0.05). The mean induction dose of propofol was significantly less in group D than in group P (p-value < 0.05). After extubation, the difference in time to the first analgesic request (NRS ≥ 4) between the groups was statistically significant (p-value < 0.05). Group D patients had a residual intraoperative analgesic effect. Conclusion The effects of dexmedetomidine and propofol infusions on desflurane consumption in laparoscopic surgeries are comparable, with minimal effects on intraoperative hemodynamics and postoperative recovery profiles.

Assessing the Anaesthetic Time on Operation Theatre Utilisation and Case Cancellation

The time to perform an anaesthesia-related procedure at induction and emergence is often overlooked as part of the operation theatre (OT) utilisation time. This prospective observational study aimed to assess the estimation done by the surgeons and anaesthetists on anaesthesia times and the overall OT utilisation in our centre. This prospective observational study included elective cases from 13 surgical disciplines. The trainees, specialists and consultants from surgical and anaesthesia teams estimated the anaesthesia times separately before the surgical procedures. The actual anaesthesia, surgical, total procedural and turnover durations taken to complete the cases were documented. Operation theatre utilisations of those various surgical disciplines involved in the study were also analysed. We analysed 128 elective cases. The average mean time spent for anaesthesia procedures was 28.4 ± 14.1 min, with the mean induction time was 16.0 ± 9.8 min and the mean emergence time was 12.5 ± 8.6 min. Both anaesthetists and surgeons overestimated the anaesthetic times, but anaesthetists estimated closer to the actual anaesthetic times (r = 0.64 vs r = 0.49, respectively). There was no significant difference in the estimated anaesthetic times between different experience levels. All the surgical disciplines had average OT utilisation exceeding 90%, indicating overutilisation. A total of 12 cases (7.1%) were cancelled. Most cases were cancelled due to exceeded allocated block OT times (7 cases) or unavailability of ICU beds (2 cases). We concluded that OTs exceeding the given OT time is the most frequent reason for cancelling elective surgical cases on the day of surgery.

Ketamine-butorphanol-medetomidine for the immobilisation of free-living hyenas (Crocuta crocuta).

Free-ranging spotted hyenas (Crocuta crocuta) are immobilised for a variety of purposes, including wildlife-human conflict mitigation, research, and veterinary treatment. Combinations of tiletamine-zolazepam (Zoletil) and medetomidine are commonly used for immobilisation of hyenas, however, recovery times are long. In this descriptive study, a total of 20 adult or subadult free-ranging hyenas were immobilised near Skukuza in the Kruger National Park using ketamine, butorphanol, and medetomidine. The goal of the study was to evaluate a suitable dose and measure cardiorespiratory effects of this combination. The quality of induction and recovery were scored using an established scoring system from 1 (excellent) to (poor). Twelve of the 20 hyenas were given an induction score of 1 (excellent), five an induction score of 2 (good), and three an induction score of 3 (fair). Of the animals with induction score = 1, the mean drug dose was 1.17 mg/kg ketamine, 0.25 mg/kg butorphanol and 0.03 mg/kg medetomidine, and the mean induction time and time to handling 6:25 minutes and 9:46 minutes respectively. The mean recovery time (from reversal to standing) was 10:16 min, which is shorter than what has been reported for tiletaminezolazepam- based combinations in hyenas. Most hyenas were bradycardic (< 40 beats per minute) and the mean PaO2 69.5 mmHg. Three hyenas, one with induction score = 2, and two with induction scores = 3 spontaneously recovered at 33, 44 and 56 minutes post approach respectively. Regardless of induction time, all hyenas reached a level of surgical anaesthesia while immobilised. Overall, ketamine-butorphanol-medetomidine (KBM) was effective in immobilising hyenas but induction times varied, and animals were bradycardic during immobilisation.

Blood collection under anesthesia, peripheral blood cells, plasma biochemistry, and plasma protein electrophoresis in a living fossil: the Spotted Ratfish (Hydrolagus colliei).

This report describes the safe and effective handling under anesthesia, blood collection and main clinical pathology values determination for three adult Spotted Ratfish (Hydrolagus colliei) (two males and one female) successfully maintained under human care for more than 20 years. The anesthetic MS-222 diluted in tamponed salt water at 50 ppm provided deep narcosis with mean induction and recovery times of 5 and 20 min, allowing safe handling and blood collection in the three animals sampled. Major leukocyte types were similar to other teleost and elasmobranch species, identifying lymphocytes as the predominant leukocyte (75.5%), followed by the fine eosinophilic granulocytes (10.25%), the coarse eosinophilic granulocytes (9.75%), and a small percentage of monocytes (5.50%). Plasma biochemistry values in this species were like those seen in elasmobranchs, with the highest levels of blood urea nitrogen described in any Chondrichthyes (mean 679.7 mmol/l). Plasma protein electrophoresis analysis in the Spotted Ratfish showed five consistent fractions, like those previously described in other fish species, with a negligible quantity of proteins migrating in the region equivalent to albumin, and with fraction 4 (mean 53.20%) as the predominant fraction. Despite the limitations imposed by the small sample size and the challenging access to the studied species under human care, this study will shed light on and enhance clinical knowledge regarding Ratfish handling, anesthesia, blood collection, and analysis. It aims to deliver a comprehensive clinical pathology description, presenting valuable data for professionals engaged in the care and management of Chimaerans.

Bacterial heat shock protein genes during induction chemotherapy in pediatric patients with acute lymphoblastic leukemia.

Background: Heat shock proteins (HSP) protect cancer cells. Gastrointestinal bacteria contain HSP genes and can release extracellular vesicles which act as biological shuttles. Stress from treatment may result in a microbial community with more HSP genes, which could contribute to circulating HSP levels. Methods: The authors examined the abundance of five bacterial HSP genes pre-treatment and during induction in stool sequences from 30 pediatric acute lymphoblastic leukemia patients. Results: Decreased mean HTPG counts (p=0.0024) pre-treatment versus induction were observed. During induction, HTPG, Shannon diversity and Bacteroidetes decreased (p=7.5e-4; 1.1e-3; 8.6e-4), while DNAK and Firmicutes increased (p=6.9e-3; 9.2e-4). Conclusion: Understanding microbial HSP gene community changes with treatment is the first step in determining if bacterial HSPs are important to the tumor microenvironment and leukemia treatment.

One-day versus two-day mifepristone–misoprostol interval prior to initiation of misoprostol during late second trimester medication abortion: A cohort study

ObjectivesTo compare one-day versus two-day mifepristone–misoprostol interval in late second trimester medication abortion. Study designThis retrospective cohort study was conducted at St. Paul’s Hospital Millennium Medical College, in Ethiopia. Data were collected retrospectively and analysed with SPSS 23 using simple descriptive analysis, t-test, Chi-squared test, and regression analysis, as appropriate. P-value < 0.05 and adjusted odds ratio (AOR) with 95% CI were used to present results significance. ResultsA total of 282 women who had medication abortion in the late second trimester (167 with one-day and 115 with two-day mifepristone-misoprostol intervals) at 20–28 weeks of gestation were analysed. Both median and mean induction to expulsion interval (I-E) were much higher in the one-day mifepristone-misoprostol (mife-miso) interval than in the two-day mife-miso interval group. The median (and mean) I-E in the one-day interval group was 24 hours (21.9+/−6.6 hours) compared to 12 hours (14.6+/−8.8 hours) in the two-day mife-miso interval group (p-value < 0.001). Expulsion rate within 12 hours of starting misoprostol was significantly higher in the two-day cohort than in the one-day cohort (73% vs 25.6%, p-value < 0.001, aOR = 19.08 95%, CI = 5.1–70.7). ConclusionsFor second trimester medication abortion at later gestation, a two-day mifepristone-to-misoprostol interval significantly reduces induction to expulsion time compared to a one-day interval. ImplicationsCompared to one-day interval, administration of mifepristone two days prior to misoprostol initiation has a shorter interval of induction to expulsion and a higher rate of abortion completion within 12 hours of initiation of misoprostol during late second trimester medication abortion.

Comparison of the Efficacy and Safety of Sublingual Versus Oral Misoprostol for the Induction of Labor: A Randomized Open-Label Study.

Introduction Misoprostol (prostaglandin E1 analog) is being used for the induction of labor by vaginal, oral, and sublingual routes. Oral misoprostol is the preferred route for induction of labor, but the use of sublingual misoprostol appears promising due to a faster onset of action. This study was done to compare the efficacy and safety of oral and sublingual misoprostol for induction of labor in term pregnancy. Materials and methods One hundred and sixty patients were randomly allocated to one of the two groups to receive 50 micrograms oforal and sublingual misoprostol four hourly for a maximum of six doses. Primigravida at 37-42 weeks of gestation with singleton pregnancy, cephalic presentation, Bishop score (<5), and reassuring fetal heart rate were included in the study. Misoprostol dose was withheldif the active phase of labor was reached or if the cervixwas favorable for amniotomy (Bishop score greater than or equal to eight). The change in the Bishop score with misoprostol was studied along with adverse effects and neonatal outcomes. Results The mean number of 50 mcg misoprostol doses required was significantly less in the sublingual group (2.94±0.97 versus 2.13±0.92; p<0.0001). The rate of change of the mean Bishop score was faster in the sublingual group. After four hours of the first dose, the mean Bishop score changed to 3.52±2.14 versus 4.68±2.34 (p=0.001), and, similarly, after eight hours, it was 10.48±2.59 versus 11.39±2.06, and this difference was statistically significant (p=0.015). The mean induction delivery interval was significantly lower in the sublingual group. The need for labor augmentation, mode of delivery, andadverse effects were similar in both groups. The incidence of meconium-stained liquor and NICU admission was also similar in both groups. Conclusion Sublingmisoprostolstol has a short induction delivery interval and comparable side effects when compared to omisoprostolstol. Sublingmisoprostolstol is recommended for induction of labor at term.

Comparison of induction-to-expulsion interval during second-trimester medication abortion in pregnancies with anencephaly and other congenital anomalies compared to those without anomalies: A retrospective cohort study

To investigate whether induction to expulsion interval during second-trimester medication abortion in pregnancies complicated by anencephaly or other fetal anomalies is prolonged compared to pregnancies without fetal anomalies STUDY DESIGN: This was a retrospective cohort study of women who had second-trimester medication abortion at St. Paul's Hospital Millennium Medical College (Addis Ababa, Ethiopia). We assigned subjects to one of three groups based on fetal diagnosis: 1) anencephaly group 2) other congenital anomaly group 3) no anomaly group. Data were collected by reviewing patients' charts. We used SPSS version 23 to analyze the data. Simple descriptive analysis and Chi-squared test were performed as appropriate. A total of 303 women had second trimester medication at 14-28 weeks, of which 58 had anencephaly, 19 had congenital anomalies other than anencephaly, and the remaining 226 had no fetal anomalies. There was no difference in induction to expulsion interval among the groups. The mean induction to expulsion interval was 18.4 hours in the anencephaly group vs, 19.4 hours in the other congenital anomaly group vs. 19.2 hours in those without anomaly (p-value=0.924). The 24-hours non-expulsion rate was also comparable among the groups, with 5.25% rate of non-expulsion in the anencephaly group vs 15.8% in the other congenital anomaly group vs 11.15 % in the no anomaly group, (p-value=0.594). In multivariable regression analysis after controlling for parity, the 24-hour non-expulsion rate was not significantly different. In this study, pregnancies undergoing second-trimester medication abortion for fetal anomalies had comparable induction to expulsion interval and 24-hour expulsion rates compared to those who had the same procedure for other or no anomalies. Second-trimester medication abortion procedure length in pregnancies complicated by anencephaly is similar to those pregnancies without anomalies. All data generated or analyzed during this study are included in this published article.

To Study the Efficacy of Intraamniotic Prostaglandin F2 Alpha versus Mifepristone and Misoprostol Combination for Mid-trimester Medical Termination of Pregnancy

Abstract Context: Aims: This study aims to compare the effectiveness, induction to abortion interval, blood loss, and side effect profile between administration of intraamniotic prostaglandin F2 alpha (PGF2α) with a combination of mifepristone and misoprostol for medical termination of pregnancy in mid-trimester. Prospective observational study. Subjects and Methods: The study was conducted by dividing the women with indicated mid-trimester abortions into two groups of 20 women each. Group-I received Tablet Mifepristone 200 mg orally on day 1 and then after 48 h, Tablet Misoprostol 400 μg given per vaginally every 4 h till abortion was completed or a maximum of 5 doses whichever was earlier. Group-II received a single injection of PGF2α (250 μg) intra-amniotically under ultrasonography guidance. Group comparisons were made using t-test/Mann–Whitney U-test for normally/nonnormally distributed continuous data, respectively, and Chi-square test for categorical variables. SPSS version 23 was used for analysis. P &lt; 0.05 was taken as the cut-off for statistical significance. Results: The success rate was 100% in both the groups. There was a significant difference in the mean induction to abortion interval between Group-I, the mean being 12.92 ± 2.68 h compared to Group-II being 33.08 ± 6.35 h (P &lt; 0.001). Group-I had a mean blood loss of 221 ± 55.15 mL, significantly more than Group-II 160 ± 25.13 mL (P &lt; 0.001). Twenty-five percent of the Group-I woman had retained products of conception with none in Group-II (P = 0.029). The pain score was better in Group II (pain score 4.4 vs. 5.7, P &lt; 0.001). Fewer women developed chills in Group II compared to Group I (0% vs. 50%, P &lt; 0.001). Conclusions: PGF2α is equally effective as a combination of Mifepristone and Misoprostol in mid-trimester abortion. Although it has a longer induction to abortion interval, it appears to be better with respect to the completeness of evacuation, lesser blood loss, and better patient tolerance.

A MIXTURE OF NALBUPHINE, AZAPERONE, AND MEDETOMIDINE FOR IMMOBILIZING RINGTAILS (BASSARISCUS ASTUTUS).

We evaluated a combination of nalbuphine HCl (40 mg/mL), azaperone tartrate (10 mg/mL), and medetomidine HCl (10 mg/mL), a combination known as NAM or NalMed-A, in 23 ringtails (Bassariscus astutus) during 29 handling events for a radio-collaring study in southern Oregon, US, from August 2020 to March 2022. The combination was delivered to ringtails by hand injection at 0.075 mL NAM per estimated 1 kg body mass. The mean (± standard deviation, SD) dosage calculated post hoc was 3.366 (±0.724) mg/kg nalbuphine, 0.841 (±0.181) mg/kg medetomidine, and 0.841 (±0.181) mg/kg azaperone. All captured ringtails were effectively immobilized with a mean (SD) induction time of 13.24 (±3.57) min. The medetomidine and nalbuphine components were antagonized with a combination of atipamezole and naltrexone HCl with a mean (SD) recovery time of 2.48 (±1.94) min. This combination appeared to be safe and effective for immobilizing ringtails with a low volume dose, smooth antagonism, and rapid recovery. In addition, NAM does not contain any drugs that are US Drug Enforcement scheduled, which makes it useful for immobilization procedures by wildlife professionals in the US.

Induction of labor via Foley balloon catheter placement for 6 vs 12 hours in women with 1 previous cesarean delivery and unfavorable cervices: a randomized controlled trial

Induction of labor in women with 1 previous cesarean delivery and unripe cervices is a high-risk process, carrying an increased risk of uterine rupture and the need for cesarean delivery. Balloon ripening is often chosen as prostaglandin use is associated with an appreciable risk of uterine rupture in vaginal birth after cesarean delivery. A shorter duration of placement of the balloon typically expedites delivery; however, this has not been evaluated in induction of labor after 1 previous cesarean delivery. This study aimed to compare Foley balloon catheter placement for 6 vs 12 hours in induction of labor after 1 previous cesarean delivery. A randomized controlled trial was conducted in a university hospital in Malaysia from January 2022 to February 2023. Eligible women with 1 previous cesarean delivery admitted for induction of labor were enrolled. Participants were randomized after balloon catheter insertion for 6 or 12 hours of passive ripening before balloon deflation and removal to check cervical status for amniotomy. The primary outcome was the induction of labor to delivery interval. The secondary outcomes were largely derived from the core outcome set for trials on induction of labor (Core Outcomes in Women's and Newborn Health [CROWN]). The Student t test, Mann-Whitney U test, chi-square test, and Fisher exact test were used as appropriate for the data. Overall, 126 women were randomized, 63 to each intervention. The mean induction of labor to delivery intervals were 23.0 (standard deviation, ±8.9) in the 6-hour arm and 26.6 (standard deviation, ±7.1) in the 12-hour arm (mean difference, -3.5 hours; 95% confidence interval, -6.4 to -0.7; P=.02). The median induction of labor (Foley balloon catheter insertion) to Foley balloon catheter removal intervals were 6.0 hours (interquartile range, 6.0-6.3) in the 6-hour arm and 12.0 hours (interquartile range, 12.0-12.5) in the 12-hour arm (P<.001). The median induction of labor to amniotomy intervals were 14.1 hours (interquartile range, 9.3-21.8) in the 6-hour arm and 19.0 hours (interquartile range, 15.9-22.0) in the 12-hour arm (P=.02). The usage rates of epidural analgesia in labor were 46.0% (29/63) in the 6-hour arm and 65.1% (41/63) in the 12-hour arm (relative risk, 0.71; 95% confidence interval, 0.51-0.98; P=.03). Spontaneous balloon catheter expulsion rates were 22.2% (14/63) in the 6-hour arm and 17.5% (11/63) in the 12-hour arm (relative risk, 1.27; 95% confidence interval, 0.63-2.58; P=.50), and additional ripening use rates (Foley reinsertion) were 46.0% (29/63) in the 6-hour arm and 31.7% (20/63) in the 12-hour arm (relative risk, 1.45; 95% confidence interval, 0.92-2.27; P=.10). The results were not different. Moreover, maternal satisfaction scores (0-10 numerical rating scale) of 9 (range, 8-10) in the 6-hour arm and 9 (range, 8-10) in the 12-hour arm (P=.41) were not different. Other secondary maternal and neonatal outcomes were not significantly different either. Foley balloon catheter placement for 6 hours hastened birth and reduced epidural analgesia use in labor without a change in maternal satisfaction.

Critical analysis of misoprostol versus mifepristone with misoprostol in medical termination of pregnancy

Termination of pregnancy by any method before the viable period is called abortion. Medical methods can avoid complications of surgical method of abortion which has many disadvantages like perforation of uterus, hemorrhage, sepsis and increased morbidity. The WHO has approved mifepristone and misoprostol combination for medical abortion. 1. To compare the efficacy of Misoprostol versus combination of mifepristone with Misoprostol. 2. To asses the side effects of Misoprostol and combinationion of Mifepristone and Misoprostol.It is prospective observational study consisting of two groups with each 61 subjects of MTP patients. Group A (Misoprostol alone): Receive tablet misoprostol 600 microgram start placed per vaginally followed by 400 microgram misoprostol tablet placed per vaginally every 4 hourly up to maximum five doses. In case of first trimester cases 800 microgram tablet misoprostol placed per vaginally followed by 400 microgram misoprostol tablet placed per vaginally every 4 hourly up to maximum four doses. Group B (Mifepristone and Misoprostol): Receive tablet mifepristone 200mg orally on empty stomach. After 24 hours will receive tablet misoprostol as mentioned in group A. Misoprostol alone has success rate of 78.69% whereas combination with Mifepristone success was 93.44%. The mean Induction - abortion interval in misoprostol alone group was 11.803 hours and with mifepristone combination it was B5.623 hours. Medical termination of pregnancy by sequential administration of mifepristone with misoprostol has less induction abortion interval compared to using misoprostol alone. This combination has more success rate and also has lesser side effects.

Cryptococcal Meningitis in Young, Immunocompetent Patients: A Single-Center Retrospective Case Series and Review of the Literature.

Cryptococcal meningitis is an uncommon but serious infection with high mortality and morbidity. Classically described in immunocompromised patients, including those with solid organ transplants or HIV/AIDS, cryptococcosis has also been reported in young and otherwise healthy patients, albeit rarely. We retrospectively searched for all cases of cryptococcal meningitis in young (≤50 years) and previously healthy patients with no known immunocompromising conditions from January 2015 to January 2022 at Indiana University Health (IU Health). Additionally, a PubMed literature review was performed with the keywords "cryptococcal meningitis" and "immunocompetent" from January 1988 to January 2022. Clinical courses, including outcomes and treatment regimens, were evaluated. We identified 4 local cases of cryptococcal meningitis in otherwise healthy patients age ≤50 years. Three cases were due to Cryptococcus neoformans, with 1 experiencing a postinfectious inflammatory response syndrome (PIIRS). The PubMed search identified 51 additional cases, with 32 (63%) being caused by Cryptococcus neoformans and 8 (17%) by Cryptococcus gattii. Of the 51 cases, only 2 resulted in death directly due to cryptococcosis. Fifteen (29%) had PIIRS, with steroid treatment documented in 11 of 15. Antifungal induction regimens and duration were varied but predominately consisted of amphotericin and flucytosine, with a mean induction duration of 5.0 weeks. Cryptococcal meningitis in young, previously healthy patients is likely under-recognized. PIIRS (akin to immune reconstitution inflammatory syndrome observed in HIV/AIDS) with prolonged recovery should be of concern. Determining risk factors for cryptococcosis in these patients remains elusive.

A PROSPECTIVE STUDY TO COMPARE COMBINED USE OF INTRAVAGINAL MISOPROSTOL AND INTRACERVICAL FOLEY CATHETER VERSUS INTRAVAGINAL MISOPROSTOL ALONE FOR TERMINATION OF MID-TRIMESTER PREGNANCY IN DEPARTMENT OF OBSTETRICS AND GYNAECOLOGY SMS MEDICAL COLLEGE, JAIPUR

Aims and Objectives: The aims and objectives of the study are to compare the mean induction to abortion interval and efficacy of intra-vaginal misoprostol alone versus combined use of intravaginal misoprostol and intracervical Foley catheter in termination of mid-trimester pregnancy. Methods: This was prospective, comparative study conducted during March 2021 to April 2022 at Department of Obstetrics and Gynaecology, SMS Medical College, Jaipur. The study included sample size of 60 cases (30 cases in each group). 60 cases were randomly allocated to either intravaginal misoprostol alone (Group A) or combined use of intravaginal misoprostol and Foley catheter (Group B) for termination of mid-trimester pregnancy. The study included all pregnant females between 14 and 20 weeks of gestation who were admitted for termination of pregnancy. Results: Mean induction to abortion interval±standard deviation for Group A was 20.79±2.01 h and for Group B, it was 17.29±3.58 h. Mean dose of tablet misoprostol required for Group A±standard deviation was 1453.3±267.47 mcg and for Group B, it was 1053.33±267.47 mcg. Conclusion: In this study, we found that with the combined use of intravaginal misoprostol and intracervical Foley catheter, there was a significant reduction in duration of induction to abortion, total dose misoprostol required, and hospital stay than in intravagnial misoprostol alone in termination of mid-trimester pregnancy.

COMPARISON OF KETAMINE-MIDAZOLAM AND KETAMINE-MIDAZOLAM-BUTORPHANOL PREMEDICATION PRIOR TO SEVOFLURANE ANESTHESIA IN WOODCHUCKS (MARMOTA MONAX).

Cardiovascular disease is a frequent cause of death in the critically endangered Vancouver Island marmots (Marmota vancouverensis). This warrants the use of anesthetic protocols with minimal cardiovascular adverse effects. In this study, 12 adult male woodchucks (Marmota monax) were used as models for Vancouver Island marmots. The objective was to compare the physiological effects of two premedication protocols during induction and maintenance of anesthesia with sevoflurane. The two premedications were ketamine 10 mg/kg and midazolam 0.5 mg/kg (KM) or ketamine 10 mg/kg, midazolam 0.5 mg/kg, and butorphanol 1.0 mg/kg (KMB), administered intramuscularly prior to mask induction. Each marmot underwent three anesthetic events and protocols were assigned using a blinded randomized crossover design. Heart rate, respiratory rate, oxygen saturation, and body temperature were recorded throughout, and blood gases were assessed following induction. Resistance to induction was scored and time to induction was recorded. Although mask induction with sevoflurane was successful in all events (mean induction time of 2.1 min), KMB premedication resulted in a faster induction (mean induction time reduced by 1.2 ± 0.3 min) and lower resistance scores. Both protocols resulted in significant cardiovascular and respiratory depression; however, animals that received KMB were more hypercapnic than KM by 8.8 ± 2.8 mm Hg (P = 0.03) (mean venous partial pressure of carbon dioxide [PvCO2] for all: 79.9 mm Hg). In conclusion, if shorter induction times are desired, KMB premedication is preferred. However, cardiorespiratory variables including blood pressure should be monitored, and endotracheal intubation is recommended to allow for ETCO2 monitoring and provision of intermittent positive pressure ventilation.

Immobilization of Raccoons (Procyon lotor) with Nalbuphine, Medetomidine, and Azaperone.

Chemical immobilization is widely used by wildlife and veterinary professionals for the safe handling of animals. A combination of nalbuphine (40 mg/mL), azaperone (10 mg/mL), and medetomidine (10 mg/mL), known as NAM, is a low-volume combination with field immobilization practicality and fewer regulations restricting its use in the US than some other drug combinations. We evaluated the safety and effectiveness of NAM as an immobilizing agent for raccoons (Procyon lotor). From May 2021 to February 2022, 16 adult raccoons were captured in cage traps and immobilized with 0.3 mL NAM intramuscularly (12 mg nalbuphine, 3 mg medetomidine, and 3 mg azaperone, regardless of body weight). After administration, time to sedation was measured; body temperature, heart rate, respiratory rate, and oxygen saturation were monitored and recorded every 5 min for 20 min. Each raccoon was weighed; the dose administered was calculated (range 2.2-4.1 mg/kg, mean 3 mg/kg). Mean induction time was 6 min (4-17 min); time to recovery following administration of 15 mg atipamezole, 7.5 mg naltrexone for reversal, was 10 min (6-18 min). Heart rate, oxygen saturation, and respiration rate remained steady during immobilization. Rectal temperature steadily declined. Overall, NAM appeared to be a practical option for raccoon immobilization, providing rapid induction and reversal as well as adequate sedation for short-term handling and minimally invasive sampling.

Differences in induction phase outcomes of acute lymphoblastic leukemia between well-nourished and malnourished pediatric patients

Background Leukemia is the most common malignancy in childhood. Malnutrition is the main nutritional disorder occurring in children with cancer. Nutritional supportive care is a medical modality that has been associated with improved tolerance to chemotherapy, survival, and quality of life, as well as decreased risk of infection in children undergoing cancer therapy.&#x0D; Objective To examine differences in induction phase outcomes in well-nourished and malnourished pediatric acute lymphoblastic leukemia (ALL) patients.&#x0D; Methods This prospective study was conducted in newly-diagnosed ALL patients aged 1 to 18 years who underwent induction phase chemotherapy at Haji Adam Malik General Hospital, Medan, North Sumatera. Mid-upper arm circumference (MUAC) was used to determine nutritional status. Patient characteristics such as complete blood count (CBC) at the time of diagnosis, occurrence of febrile neutropenia, duration of induction, length of hospital stay, and remission status were collected. We analyzed differences in CBC, frequency of febrile neutropenia, as well as duration of induction and hospital stay between well-nourished and malnourished patients. We also assessed the difference in remission attainment between the two groups.&#x0D; Results There were 21 subjects in each group. Compared to well-nourished subjects, malnourished ones had a higher median incidence of febrile neutropenia [1 (range 0 to 30) vs. 3 (range 0 to 4); P=0.04], longer mean induction duration [64.2 (SD 11.5) vs. 71.2 (SD 10.6) days; P=0.046], and longer median hospital stay [30 (range 19 to 56) vs. 36 (range 22 to 49) days; P=0.001] compared to well-nourished subjects. There was no significant difference in CBC parameters and remission status after induction between the two groups.&#x0D; Conclusion Malnourished pediatric ALL patients had a significantly higher incidence of febrile neutropenia, duration of induction phase, and duration of hospital stay compared to well-nourished ALL patients.

The effect of induced fetal demise on induction to expulsion interval during later medication abortion: A retrospective cohort

ObjectivesTo investigate the effect of induced fetal demise on the induction to expulsion interval during later trimester medication abortion. Study designThis retrospective cohort was conducted at St. Paul’s Hospital Millennium Medical College, Ethiopia. Later medication abortion cases that had induced fetal demise were compared to matching cases with no induced fetal demise. Data were collected by reviewing maternal charts and analyzed using SPSS version 23. Simple descriptive analysis, χ2 test, and multiple logistic regression analysis were used as appropriate. Odds ratio, 95% CI, and p-value<0.05 were used to present the significance of the findings. ResultsA total of 208 patient charts were analyzed. Seventy-nine patients were provided with intra-amniotic digoxin, 37 patients were provided with intracardiac lidocaine, and 92 had no induced demise. The mean induction to expulsion interval was 17.8 hours in the intra-amniotic digoxin group, which is not statistically different than 19.3 hours in the intracardiac lidocaine and 18.5 hours in the group without induced fetal demise (p-value = 0.61). Expulsion rate after 24 hours was not statistically different among the three groups (5.1% in the digoxin group vs 10.6% intracardiac lidocaine group vs 7.8% in the no induced fetal demise group, p-value = 0.82). Multivariate regression analysis demonstrated that inducing fetal demise was not associated with successful expulsion at<24 hours (adjusted odds ratio [AOR] = 0.19, 95% CI, 0.03–1.29 and AOR = 0.62, 95% CI, 0.11–3.48, for digoxin and lidocaine, respectively) from induction. ConclusionsIn this study, inducing fetal demise using digoxin or lidocaine prior to later medication abortion was not associated with a reduction in the induction to expulsion interval. ImplicationsDuring later medication abortion with mifepristone and misoprostol, inducing fetal demise may not be associated with a change in the length of the procedure. Induced fetal demise may be required for other reasons.
