Trans-abdominal fetal reduction in higher order multiple pregnancies: a pioneer cohort retrospective study in Nepal.

Objective: To share the initial experience of trans-abdominal multifetal pregnancy reduction (MFPR) in Nepal. Method: The procedure was performed in 108 patients in a private hospital over a period of 3 years. Under ultrasound guidance, intracardiac injection of 0.2-3.0 ml of 15% w/v (2 mEq/ml) potassium chloride (KCl) was administered via trans-abdominal route. Results: A total of 108 fetal reduction procedures were carried out at the seventh to fifteenth weeks of gestation, a maximum of 44 (40.7%) of which were done at the ninth to tenth weeks of gestation. A total of 123 fetuses were reduced. Out of total 108 multifetal pregnancies, 96 (88.8%) were due to in-vitro fertilization (IVF). Eighty-five pregnancies (78.7%) underwent reduction from triplet to twin. The second-time reduction was needed in five cases. Two attempts (in the same sitting) were required in three cases. The inadvertent demise of the second fetus was noted in three cases of dichorionic tri-amniotic triplet pregnancy. Conclusion: Ultrasound-guided trans-abdominal fetal reduction performed between the seventh and twelfth weeks of gestation is safe and effective.

κ-Carrageenan masking bitterness perception in surimi gels containing potassium chloride-based salt substitutes: Gel properties, oral processing, and sensory evaluation.

κ-Carrageenan (CG) was employed to mask the bitterness induced by 50% KCl in surimi gels to achieve salt reduction and gel performance improvement. The combination of KCl and CG (KCl + CG) yielded the increased textural characteristics and water-holding capacity (WHC) of surimi gels and facilitated the transition of free water to immobilized water. In addition, the KCl + CG supplement increased the turbidity and particle size of myofibrillar protein (MP) sols but decreased the surface hydrophobicity in a dose-dependent manner. The hydrophobic interactions and disulfide bonds played crucial roles in maintaining the stability of MP gels. The specific binding of potassium ions to the sulfate groups of CG limited the release and diffusion of potassium ions from the surimi gels during oral processing, effectively masking the bitterness perception and maintaining the saltiness perception. This study provides a promising strategy to reduce the utilization of sodium salt in surimi products.

Region and layer-specific expression of GABAA receptor isoforms and KCC2 in developing cortex.

Introduction: γ-Aminobutyric acid (GABA) type A receptors (GABAARs) are ligand-gated Cl-channels that mediate the bulk of inhibitory neurotransmission in the mature CNS and are targets of many drugs. During cortical development, GABAAR-mediated signals are significantly modulated by changing subunit composition and expression of Cl-transporters as part of developmental processes and early network activity. To date, this developmental evolution has remained understudied, particularly at the level of cortical layer-specific changes. In this study, we characterized the expression of nine major GABAAR subunits and K-Cl transporter 2 (KCC2) in mouse somatosensory cortex from embryonic development to postweaning maturity. Methods: We evaluated expression of α1-5, ß2-3, γ2, and δ GABAAR subunits using immunohistochemistry and Western blot techniques, and expression of KCC2 using immunohistochemistry in cortices from E13.5 to P25 mice. Results: We found that embryonic cortex expresses mainly α3, α5, ß3, and γ2, while expression of α1, α2, α4, ß2, δ, and KCC2 begins at later points in development; however, many patterns of nuanced expression can be found in specific lamina, cortical regions, and cells and structures. Discussion: While the general pattern of expression of each subunit and KCC2 is similar to previous studies, we found a number of unique temporal, regional, and laminar patterns that were previously unknown. These findings provide much needed knowledge of the intricate developmental evolution in GABAAR composition and KCC2 expression to accommodate developmental signals that transition to mature neurotransmission.

A Case Report and Literature Review of Death by Potassium Chloride: Is it a Forensic Medicine Enigma?

The diagnosis of death from potassium chloride (KCl) injection is complex because it is a natural ion, so it is very difficult to trace the exogenous administration of drugs containing potassium. In these cases, it is important to perform a careful cadaver inspection, with the collection of circumstantial data on the scene, and proper autopsy investigations, in order to avoid errors regarding the reconstruction of the cause of death. The aim of this paper is to propose a forensic protocol, including evidence collected from the literature, that could help the medical examiner to perform the correct diagnosis, and also encourage control measures to avoid similar events, especially in nosocomial environments. This is important, especially for health professionals who can easily access drugs containing potassium. For this reason, we need to strengthen control measures of these drugs by proposing a double check in cases of pharmacological use, specifying the volume taken with a double authorization signature and the reasons for the withdrawal.

Diagnosis, management and outcomes of primary hypokalemic periodic paralysis during pregnancy.

Primary hypokalaemic periodic paralysis during pregnancy has been rarely reported. Four pregnant women with the acute onset of flaccid paralysis presented between January 2018 and December 2021. Focussed history and physical examination helped an appropriate radiological and laboratory investigation plan to be made. All women recovered within 4-7 days of potassium supplementation. Supplemental potassium continued until delivery. A pain management plan with continuous epidural infusion helped in avoiding stress-induced hypokalaemia. None of the women developed an episode of muscle weakness during the intervening period. In conclusion, a focussed history and targeted laboratory investigation are needed to diagnose primary hypokalaemic periodic paralysis. Early administration of oral or intravenous potassium is crucial in improving fetomaternal outcomes.

Reduced Gene Expression of KCC2 Accelerates Axonal Regeneration and Reduces Motor Dysfunctions after Tibial Nerve Severance and Suturing.

Gamma-aminobutyric acid and glycine (GABA/Gly) are predominantly inhibitory neurotransmitters in the mature central nervous system; however, they mediate membrane potential depolarization during development. These differences in actions depend on intracellular Cl- concentrations ([Cl-]i), which are primarily regulated by potassium chloride cotransporter 2 (KCC2). After nerve injury, KCC2 expression markedly decreases and GABA/Gly mediate depolarization. Following nerve regeneration, KCC2 expression recovers and GABA/Gly become inhibitory, suggesting that KCC2 reduction and GABA/Gly excitation may be crucial for axonal regeneration. To directly clarify their involvement in regeneration, we analyzed recovery processes after tibial nerve severance and suturing between heterozygous KCC2 knockout mice (HT), whose KCC2 levels are halved, and their wild-type littermates (WT). Compared with WT mice, the sciatic functional index-indicating lower limb motor function-was significantly higher until 28 days after operation (D28) in HT mice. Furthermore, at D7, many neurofilament-positive fibers were elongated into the distal part of the sutured nerve in HT mice only, and myelinated axonal density was significantly higher at D21 and D28 in HT animals. Electron microscopy and galanin immunohistochemistry indicated a shorter nerve degeneration period in HT mice. Moreover, a less severe decrease in choline acetyltransferase was observed in HT mice. These results suggest that nerve degeneration and regeneration proceed more rapidly in HT mice, resulting in milder motor dysfunction. Via similar microglial activation, nerve surgery may reduce KCC2 levels more rapidly in HT mice, followed by earlier increased [Cl-]i and longer-lasting GABA/Gly excitation. Taken together, reduced KCC2 may accelerate nerve regeneration via GABA/Gly excitation.

Potassium Chloride as an Effective Alternative to Sodium Chloride in Delaying the Thermal Aggregation of Liquid Whole Egg.

The potential of potassium chloride (KCl) to be used as a substitute for sodium chloride (NaCl) was studied by monitoring the effects of salt treatment on thermal behavior, aggregation kinetics, rheological properties, and protein conformational changes. The results show that the addition of KCl can improve solubility, reduce turbidity and particle size, and positively influence rheological parameters such as apparent viscosity, consistency coefficient (K value), and fluidity index (n). These changes indicate delayed thermal denaturation. In addition, KCl decreased the content of ß-sheet and random coil structures and increased the content of α-helix and ß-turn structures. The optimal results were obtained with 2% KCl addition, leading to an increase in Tp up to 85.09 °C. The correlation results showed that Tp was positively correlated with solubility, α-helix and ß-turn but negatively correlated with ΔH, turbidity, ß-sheet and random coil. Overall, compared to NaCl, 2% KCl is more effective in delaying the thermal aggregation of LWE, and these findings lay a solid theoretical foundation for the study of sodium substitutes in heat-resistant liquid egg products.

A novel pathogenic SLC12A5 missense variant in epilepsy of infancy with migrating focal seizures causes impaired KCC2 chloride extrusion.

The potassium-chloride co-transporter 2, KCC2, is a neuron-specific ion transporter that plays a multifunctional role in neuronal development. In mature neurons, KCC2 maintains a low enough intracellular chloride concentration essential for inhibitory neurotransmission. During recent years, pathogenic variants in the KCC2 encoding gene SLC12A5 affecting the functionality or expression of the transporter protein have been described in several patients with epilepsy of infancy with migrating focal seizures (EIMFS), a devastating early-onset developmental and epileptic encephalopathy. In this study, we identified a novel recessively inherited SLC12A5 c.692G>A, p. (R231H) variant in a patient diagnosed with severe and drug-resistant EIMFS and profound intellectual disability. The functionality of the variant was assessed in vitro by means of gramicidin-perforated patch-clamp experiments and ammonium flux assay, both of which indicated a significant reduction in chloride extrusion. Based on surface immunolabeling, the variant showed a reduction in membrane expression. These findings implicate pathogenicity of the SLC12A5 variant that leads to impaired inhibitory neurotransmission, increasing probability for hyperexcitability and epileptogenesis.

Formulation and Characterization of Glucosamine Sulphate Potassium Chloride (GSPC) Loaded Emulgel for the Treatment of Osteoarthritis.

BACKGROUND: Osteoarthritis (OA) is becoming a major medical burden worldwide due to changing lifestyles and aging populations. Osteoarthritis is a disease characterized by a variety of anatomic and physiological changes to joints, including cartilage degradation, bone remodeling, and the formation of osteophytes. These changes cause pain, stiffness, swelling, and limitations in joint function. Glucosamine serves as a fundamental constituent for cartilage, the resilient connective tissue responsible for cushioning joints. Glucosamine Sulphate Potassium Chloride (GSPC) supplementation is widely employed to mitigate symptoms linked to osteoarthritis, a degenerative joint disorder hallmarked by cartilage degradation. AIM: Palliative care aims at minimizing pain and disability and improving function, performance, and quality of life. In this study, the emulgel formulation of GSPC was developed and checked for its potential. OBJECTIVE: Currently, OA does not have a definitive treatment. Since conventional dosage forms cannot deliver the active drug content at a predefined target site in a predictable manner throughout the treatment period, a new carrier system is always required. Considering their reduced size, targeting potential, and site specificity, nanocarrier-based approaches could hold an answer to shortcomings associated with conventional routes. Thus, the objective of the current study was to formulate and characterize glucosamine sulphate potassium chloride-loaded emulgel for the treatment of osteoarthritis. METHODS: Microemulsion of glucosamine sulphate potassium chloride was formulated using a spontaneous emulsification method comprising of oleic acid (oil phase), Tween 80, Tween 20 (surfactant) and PEG 400, Span 80 (co-surfactant), and distilled water (aqueous phase). The microemulsions were evaluated for surface morphology, globule size, poly-dispersibility index (PDI), zeta potential, and viscosity, and the final batch of microemulsions was selected. RESULT: The optimized microemulsion contained 35% co-surfactant (propylene glycol), 20% surfactant (Tween 20), and 15% oil (oleic acid) and glucosamine sulphate potassium chloride in a dose of 60 mg, which has sufficient drug loading capacity with a droplet size of 182 nm for optimized formulation. The optimized microemulsion formulation was added to gel prepared by Carbopol 934 in a 1:1 (w/w) ratio, leading to the formulation of glucosamine sulphate potassium chloride- containing emulgel. The prepared emulgel was further evaluated for viscosity, drug content, pH, and in-vitro drug release. Emulgel formulation (F6) showed 88% drug release after 6 hours, and it followed the Higuchi model. CONCLUSION: Glucosamine Sulphate Potassium Chloride (GSPC) is used in the treatment of OA by increasing the production of proteoglycans, which can cause the cartilage to break down. Emulgel formulation (F3) showed 75.41% drug release, and formulation (F6) showed 88% drug release after 6 h. Therefore, it may be concluded that an emulgel of GSPC can be used as a controlled-release dosage form of the drug for local application in OA.

The potential for current sodium and potassium production to support a global switch to the use of potassium-enriched salt: a desktop research study.

OBJECTIVE: Switching regular salt (sodium chloride) to salt enriched with potassium chloride (25 % potassium chloride, 75 % sodium chloride) has been shown to reduce blood pressure and the risk of cardiovascular diseases. We sought to define the potential for the current production of sodium chloride and potassium chloride to support a global switch to the use of potassium-enriched salt. DESIGN: We summarised data from geological surveys, government reports and trade organisations describing the global production and supply of sodium chloride and potash (the primary source of potassium chloride) and compared this to potential requirements for potassium-enriched salt. SETTING: Global. PARTICIPANTS: Not applicable. RESULTS: Approximately 280 million tonnes of sodium chloride were produced in 2020 with China and the USA the main producers. Global production of potash from which potassium chloride is extracted was about forty-four million tonnes with Canada, Belarus, Russia and China providing 77 % of the world's supply. There were forty-eight countries in which potassium-enriched salt is currently marketed with seventy-nine different brands identified. Allowing for loss of salt between manufacture and consumption, a full global switch from regular salt to potassium-enriched salt would require about 9·7 million tonnes of sodium chloride to be replaced with 9·7 million tonnes of potassium chloride annually. CONCLUSIONS: Significant upscaling of the production of potassium chloride and the capacity of companies able to manufacture potassium-enriched salt, as well as a robust business case for the switch to potassium chloride, would be required.

The review defines fetal reduction and underscores its significance in mitigating risks associated with heterotopic pregnancies, including the threat of rupture, maternal morbidity, and adverse outcomes. The analysis encompasses the background, methods, efficacy, ethical considerations, and future directions related to the procedure. Findings highlight the efficacy and safety of potassium chloride infusion, emphasizing the importance of proper patient selection and counseling. Implications for clinical practice underscore the procedure's viability in specific cases where the benefits outweigh the associated risks. The review concludes with recommendations for future studies, encouraging further research on procedural techniques, alternative methods, and the psychosocial impact on patients. This work is a foundation for advancing the management of unruptured heterotopic pregnancies, providing insights for clinicians and researchers to improve clinical outcomes and patient care.

A strategy for the investigation of toxic mechanisms and protection by efflux pumps using Schizosaccharomyces pombe strains: Application to rotenone.

Effects not related with the inhibition of complex I of the mitochondrial electron transport chain are studied in S. pombe, which lacks it. This study aims: First, the use of a strategy with S. pombe strains to investigate the toxicity, mechanisms of action, interactions and detoxication by efflux pumps. Second, to investigate the mechanisms of toxic action of rotenone. In the dose-response assessment, the yeast presented a good correlation with the toxicity in Daphnia magna for 15 chemicals. In the mechanistic study, the mph1Δ strain presented marked specificity to the interaction with microtubules by carbendazim. DNA damage caused by hydroxyurea, an inhibitor of deoxynucleotide synthesis, was identified with marked specificity with the rad3Δ strain. The sty1Δ strain was very sensitive to the oxidative and osmotic stress induced by hydrogen peroxide and potassium chloride, respectively, being more sensitive to oxidative stress than the pap1Δ strain. The protection by exclusion pumps was also evaluated. Rotenone presented low toxicity in S. pombe due to the lack of its main target, and the marked protection by the exclusion transporters Bfr1, Pmd1, Caf5 and Mfs1. Marked cellular stress was detected. Finally, the toxicity of rotenone could be potentiated by the fungicide carbendazim and the antimetabolite hydroxyurea. In conclusion, the use of S. pombe strains is a valid strategy to: a) assess global toxicity; b) investigate the main mechanisms of toxic action, particularly spindle and DNA interferences, and osmotic and oxidative stress not related to complex I inhibition; c) explore the detoxication by efflux pumps; and d) evaluate possible chemical interactions. Therefore, it should be useful for the investigation of adverse outcome pathways.

"Five birds one stone" tri-modal monitoring driven lab-on-magnetic aptasensor for accurate pathogen detection and enhanced germicidal application.

The effective combination of ultra-precise detection and on-demand sterilization stands out as one of the most valuable antifouling methods to combat pathogenic bacteria source and ensure the environment and food safety. Herein, an innovative "five birds one stone" aptasensor has been reported. It integrates magnetic separation, tri-modal precision detection, and efficient sterilization for monitoring of Staphylococcus aureus. Firstly, as a switch of the aptasensor, aptamer-modified potassium chloride-doped carbon dots (apt/KCl@CDs) could be adsorbed onto the surface of magnetic multi-walled carbon nanotube composites (M-MWCNTs) through π-π stacking, which could be replaced by the specific binding of the target bacteria to the aptamer. The mutual interference between the nanomaterials could be eliminated by this reverse magnetosorption strategy, enhancing the test sensitivity. In addition to the fluorescence properties, the peroxidase activity possessed by apt/KCl@CDs enables the conversion of the (3,3',5,5'-tetramethylbenzidine) TMB-H2O2 colorimetric system to a photothermal modal. Then, the ultra-precision detection in the assay was achieved by the fluorescence-colorimetric-photothermal tri-modal sensing from the formation of S. aureus-apt/KCl@CDs in the supernatant. Besides, the efficient sterilization could be ensured by adsorbing the apt/KCl@CDs on the surface of S. aureus, generating toxic •OH for direct attacking cells. This was the first report that was more beneficial for bacterial eradication. The detection limits of fluorescence, colorimetric and photothermal modals were 4.81 cfu/mL, 3.40 cfu/mL and 6.74 cfu/mL, respectively. The magnetic nanoplatform integrating tri-modal detection-sterilization meets the demand for highly sensitive and precise detection in different scenarios, providing immediate control for pathogens and broad application prospects.

[Inability of hospital computerised physician order entry systems to secure the use of concentrated potassium intravenous solutions]. / Incapacité des logiciels d'aide à la prescription hospitaliers à sécuriser l'utilisation des solutions concentrées de potassium injectable.

OBJECTIVES: To determine whether hospital computerised physician order entry (CPOE) systems contribute to securing intravenous potassium chloride (KCl) prescriptions with reference to the recommendations issued by French healthcare agencies. METHODS: We sent a questionnaire to the members of the Association pour le Digital et l'Information en Pharmacie. RESULTS: More than three quarters of the 84 responses received involving 23 CPOE systems indicate that it is possible to: prescribe an ampoule of concentrated potassium chloride 10% 10mL intravenously without any diluents (80%); prescribe 4g of KCl in a bag of 500mL of NaCl 0,9% (98%); prescribe a solution that contains 6 grams of KCl per liter (94%); prescribe the administration of an injectable ampoule orally by means of a free text comment (83%). Nearly half of the responses indicate that it is possible to prescribe: concentrated KCl ampoules as administration solvent (50%); an injectable vial to be administered by oral route (52%). CONCLUSION: At least 23 hospital CPOE systems are unable to secure the prescriptions of injectable KCl. This finding lifts the veil on an unthought, namely the role of CPOE systems in securing high-risk medications. In order to solve this problem, it should be mandatory that health information technology vendors pay particular attention to these drugs. With regard to injectable KCl, the utilisation of a dilution vehicle, maximum concentration and maximum infusion flow rate are the first four constraints to be satisfied.

Case Report of an exceptional spontaneous abdominal heterotopic pregnancy with superfetation: Diagnosis and treatment: Heterotopic pregnancy with superfetation (8+1 WG & 5+4 WG).

Heterotopic pregnancy is an extremely rare condition in which an intrauterine and an extrauterine pregnancy co-exist. In spontaneous conceptions, heterotopic pregnancy occurs in only 1/30 000 pregnancies. The treatment of heterotopic pregnancy must be as minimally invasive as possible to preserve the development of the intrauterine pregnancy. Superfetation, defined as the coexistence of 2 or more foetuses of different gestational ages, remains particularly exceptional and poorly explained (second ovulation? embryonic diapause?). Here, we present an extremely rare case of a spontaneous heterotopic evolutive pregnancy with superfetation, consisting of an embryo in the pouch of Douglas estimated at 8 + 1 weeks of gestation (WG) and a progressive intrauterine pregnancy estimated at 5 + 4 WG. We treated the extrauterine pregnancy with an intra-cardiac injection of potassium chloride echo-guided via the vaginal route, and the patient then underwent exploratory laparoscopy 9 days later and lavage and aspiration of the abdominal heterotopic pregnancy due to pain and biological inflammatory syndrome probably caused by pelvic mass syndrome and peritoneal irritation from the foetal necrosis. She has not yet given birth and is currently at 36 WG.

Feticide Before Termination of Pregnancy in Singleton Pregnancy - Trends in England and Wales 2012-2020, a Cross-sectional Study.

Feticide is the practice of inducing fetal demise before the termination of pregnancy. In England and Wales, it is recommended for terminations of pregnancy beyond 21+6 weeks of gestation. This project analyses the trends in feticide in singleton pregnancy in England and Wales between 2012 and 2020. This project was a retrospective study that analysed data extracted from the Health and Social Act 4 (HSA4) forms submitted to the Department of Health and Social Care (DHSC). The data extracted by the DHSC included the prevalence of feticide, methods of feticide and termination, statutory grounds, gestation, service provider, maternal age, ethnicity and obstetric history. In addition, data analysis was carried out to identify trends. Between 2012 and 2020, there were 9310 feticides in England and Wales, undertaken in 0.5% of all abortions. The prevalence of feticide fluctuated; however, there was an overall decrease from 1084 cases in 2012 to 1000 cases in 2020. Intracardiac injection of potassium chloride was the most frequent method of achieving feticide (67.2%). Just over half (55.8%) of feticides took place under Ground E of the Abortion Act 1967, with the main indication being congenital malformations of the nervous system. Two-fifths (40.2%) of feticides took place at 23 weeks, 22.8% at 22 weeks and 13.5% between 20 and 21 weeks. The remainder occurred at later gestations: 17.5% at 24-29 weeks and 5.9% beyond 29 weeks. During our study period, it was more common for feticides to be carried out as part of a medical termination than a surgical termination and 60.3% occurred in NHS hospitals. Women undergoing feticide were mostly aged 30-34 years (38.3%) and of White ethnicity (78.6%). Feticide is an essential component of comprehensive abortion care for women undergoing late second and third-trimester abortions. This study provides insight into how feticide is carried out in England and Wales and demonstrates the effect of the COVID-19 pandemic on reducing feticide prevalence. Future research should analyse in more detail the use of the different methods of feticide.

Effects of Different Flotation Agents on the Nucleation and Growth of Potassium Chloride.

The flotation agent is an important collector in the production of potassium chloride and is brought into the crystallization stage with the reflux of the mother liquor. Octadecylamine Hydrochloride (ODA), 1-Dodecylamine Hydrochloride (DAH) and Sodium 1-dodecanesulfonate (SDS) were selected to study their effect on the nucleation of potassium chloride. Focused Beam Reflectance Measurement was used to collect the nucleation-induced periods of KCl in the presence of flotation agents at different supersaturations. Then, empirical equations, classical nucleation theory and growth mechanism equations were employed for data analysis. It was found that the presence of flotation agents increased the nucleation sequence m, and m(ODA) > m(SDS) > m(DAH) > m(H2O). In addition, the interfacial energy data obtained using classical nucleation theory suggest that the flotation agents used in our paper promoted the homogeneous nucleation of KCl (reduced from 5.3934 mJ·m-2 to 5.1434 mJ·m-2) and inhibited the heterogeneous nucleation of KCl (increased from 2.8054 mJ·m-2 to 3.6004 mJ·m-2). This investigation also revealed that the growth of potassium chloride was consistent with the 2D nucleation-mediated growth mechanism, and the addition of flotation agent did not change the growth mechanism of potassium chloride. Finally, the particle size distribution results were exactly consistent with the order of nucleation order m. The study of nucleation kinetics and growth mechanisms of different flotation agents on potassium chloride can provide guidance for optimizing the production process of potassium chloride and developing new flotation agents.

An unusual stroke mimic: A case report.

Hypokalaemic paralysis is a rare disorder characterized by rapid onset of symmetrical flaccid skeletal muscle weakness in the presence of reduced serum potassium levels. It is categorized as primary or secondary depending on the aetiology. Asymmetric or unilateral muscle weakness in hypokalaemic patients is a rare presentation. In patients with comorbid cardiovascular risk factors, this atypical manifestation can mimic acute stroke. Only a few of such cases have been reported in the literature. This report discusses the case of a 46-year-old hypertensive Ghanaian woman who presented to a District Hospital with sudden-onset right-sided flaccid weakness and a high blood pressure. Acute stroke was ruled out with computed tomography scan of the brain. Further laboratory evaluation demonstrated reduced serum potassium level, which was corrected with subsequent dramatic resolution of the muscle weakness.

Successful Non-surgical Management of Cesarean Scar Pregnancy.

Ectopic pregnancy in the scar of a previous cesarean section contributes to significant maternal morbidity in the first trimester due to a significantly higher risk of uterine rupture if left undetected. The routine scans done in the first trimester serve as an important screening tool in the detection of such an ectopic pregnancy. Early detection can aid in making a paradigm shift from a surgical to a more conservative approach for the management of such pregnancies. Here, we report a case of a cesarean scar pregnancy diagnosed in the sixth week of gestation which was managed non-surgically with methotrexate and intracardiac potassium chloride injection.
