Uso de ibuprofeno en el tratamiento de pacientes pediátricos con poliuria y disnatremia. Reporte de una serie de casos / Ibuprofen use for the treatment of pediatric patients with polyuria and dysnatremia. A case series report

Los niños con lesiones selares y/o supraselares pueden presentar diabetes insípida central con posterior secreción inadecuada de hormona antidiurética. Nosotros observamos, en algunos casos, aumento de la incidencia de poliuria, natriuresis e hiponatremia, tríada diagnóstica del síndrome cerebral perdedor de sal. Aquí comunicamos la evolución de 7 pacientes con antecedentes de daño agudo del sistema nervioso central y diabetes insípida central seguida por síndrome cerebral perdedor de sal. Como tratamiento aportamos secuencialmente fluidos salinos parenterales, cloruro de sodio oral, desmopresina, mineralocorticoides e incluso tiazidas. Ante la persistencia de poliuria con hiponatremia, agregamos ibuprofeno. Como resultado de este esquema terapéutico secuencial, este grupo redujo significativamente los valores de diuresis diaria de 10 ml/kg/h a 2 ml/kg/h en un tiempo promedio de 5 días, normalizando también las natremias (de 161 mEq/L a 143 mEq/L) en un tiempo promedio de 9 días. En ningún caso observamos efectos adversos asociados al tratamiento.

Children with sellar and/or suprasellar lesions may develop central diabetes insipidus with subsequent inappropriate antidiuretic hormone secretion. An increased incidence of polyuria, natriuresis, and hyponatremia has been reported in some cases, which make up the diagnostic triad of cerebral salt wasting syndrome. Here we report the clinical course of 7 patients with a history of acute central nervous system injury and central diabetes insipidus followed by cerebral salt wasting syndrome. Treatment included the sequential use of parenteral saline solution, oral sodium chloride, desmopressin, mineralocorticoids, and even thiazides. Due to persistent polyuria and hyponatremia, ibuprofen was added. As a result of this sequential therapeutic regimen, daily urine output reduced significantly from 10 mL/ kg/h to 2 mL/kg/h over an average period of 5 days, together with a normalization of natremia (from 161 mEq/L to 143 mEq/L) over an average period of 9 days. No treatment-related adverse effects were observed in any case.

Poliuria post-obstructiva. Análisis fisiopatológico de un caso / Post-obstructive polyuria. Pathophysiological analysis of a case

The relief of the impediment to urinary flow is the treatment of acute kidney failure due to urinary tract obstruction. However, there is a risk of inducing massive polyuria, which can be self-limited or produce severe contraction of the intravascular volume with pre-renal acute kidney failure and alterations in the internal environment. Polyuria, urine output > 3 L/d or > 200 mL/min for more than 2 hours, can have multiple causes, and can be classified as osmotic, aqueous or mixed. Post-obstructive polyuria obeys different pathogenic mechanisms, which overlap and vary during a patient's evolution. Initially, there is a decrease in vasoconstrictor factors and an increase in renal blood flow, which, added to the excess of urea accumulated, will cause intense osmotic diuresis (osmotic polyuria due to urea). Added to these factors are the positive sodium and water balance during acute renal failure, plus the contributions of crystalloid solutions to replace diuresis (ionic osmotic polyuria). Finally, there may be tubular dysfunction and decreased solutes in the renal medullary interstitium, adding resistance to the action of vasopressin. The latter causes a loss of free water (mixed polyuria). We present the case of a patient with post-obstructive polyuria where, by analyzing the clinical symptoms and laboratory alterations, it was possible to interpret the mechanisms of polyuria and administer appropriate treatment for the pathogenic mechanism.

Rabdomiólisis asociada con hipocalemia en el embarazo y aspectos perinatales. Reporte de un caso clínico / Rhabdomyolysis associated with hypokalemia in pregnancy and perinatal aspects. A case report

Resumen ANTECEDENTES: La rabdomiólisis es un síndrome causado por una lesión en las fibras musculares que produce la liberación de componentes intracelulares (mioglobina, creatinfosfocinasa, aldolasa y lactato deshidrogenasa; electrolitos) hacia el espacio extracelular y la circulación sanguínea, lo que resulta en complicaciones graves (alteraciones cardiovasculares, edema cerebral y muerte). Existen pocos casos reportados de rabdomiólisis durante el embarazo, los informes descritos en la bibliografía se enfocan en infecciones y alteraciones hidroelectrolíticas. CASO CLÍNICO: Paciente de 28 años, primigesta, que inició con alteraciones musculares luego de un cuadro infeccioso, en la semana 18 del embarazo, por lo que se le practicaron estudios para encontrar la causa del desequilibrio hidroelectrolítico (determinación de hipocalemia), con elevación súbita de creatinfosfocinasa. El urocultivo resultó positivo a Escherichia coli. El tratamiento consistió en reposición hidroelectrolítica, con administración de potasio ajustado a los requerimientos de la paciente, antibiótico y aporte nutricional, con alta hospitalaria a los dos días. Continuó en control prenatal y en la semana 32.2 tuvo preeclampsia, por lo que se decidió efectuar cesárea, de la que se obtuvo un recién nacido masculino, de 2395 g, Apgar 9/9, con evolución satisfactoria de la madre y su hijo. CONCLUSIONES: El embarazo es un estado fisiológico que implica mayor susceptibilidad de infecciones o complicaciones asociadas con desequilibrio hidroelectrolítico. Es importante considerar la rabdomiólisis durante el embarazo; el diagnóstico se establece mediante examen clínico y estudios de laboratorio.

Abstract BACKGROUND: Rhabdomyolysis is a syndrome, caused by injury to the muscle fiber, which produces the release of intracellular components such as myoglobin, creatine kinase, aldolase and lactate dehydrogenase, electrolytes, into the extracellular space and blood circulation, which can cause serious complications. such as cardiovascular disorders, cerebral edema and death. There are few reported cases of rhabdomyolysis in pregnancy, the reports described in the literature have been associated with infections and hydroelectrolytic changes. The clinical case is presented due to the importance of the repercussion to the maternal-fetal binomial, since it can result in a serious outcome. CLINICAL CASE: The case of a primiparous pregnant patient is presented, who debuted with clinical symptoms accompanied by muscular alterations after an infection, in week 18 of gestation, for which a study protocol was requested with the finding of hydroelectrolyte imbalance, of the hypokalemia type, with sudden elevation of creatine phosphokinase. A positive urine culture for Escherichia coli was found. Management with hydroelectrolyte replacement was indicated, with potassium replacement adjusted to requirements, antibiotic, and nutritional contribution, with hospital discharge after 2 days. Prenatal control was continued and at week 32.2 she presented preeclampsia, which is why a cesarean section was decided, a male weighing 2395 g, Apgar 9/9, with satisfactory evolution of the binomial was obtained. CONCLUSIONS: Pregnancy is more susceptible to infections or complications associated with hydroelectrolyte imbalances, rhabdomyolysis can occur in pregnancy, and it is important not to rule it out, its diagnosis can be made clinically and through laboratory tests.

Role of preoperative assessment of serum sodium in transurethral resection of prostate to avoid transurethral resection of prostate syndrome: a comparative study

Background: Transurethral resection of prostate syndrome (TURP) syndrome is an iatrogenic complication caused by absorption of the irrigating fluid which is used to distend the bladder during surgery.Methods: A total of 100 patients with benign prostatic hyperplasia (BPH) were taken for study. Study was done in tertiary care centre in Gujarat from January 2016 to December 2017. They were evaluated pre-operative and post-operative for sodium concentration.Results: In this study most of the patients i.e. 32 were seen in age group 61- 65 years.31% cases have developed hyponatremia out of 6% were having serum sodium level <125 mEq/l. 56% of cases were having prostate gland <40 cc. In 70% cases, TURP was completed within 60 minutes, while 30% cases required more than 60 minutes time. 13 were seen in age group 51 to 60 years, means 40.62% patients of this age group (13/32) and 12 patients were seen in age group 71-80 years, means 52.17% patients of this age group (12/23) were having post-operative hyponatremia. Out of 31 patients, 20 patients (64.52%) were having prostate size more than 60 cc and 11 patients (35.48%) were having prostate size between 46 to 60 cc.Conclusions: From present study, it is concluded that electrolyte derangement occurs in older patients, with larger amount of tissue and longer time of resection and higher volume of irrigation fluid. It was also noticed that chances of electrolyte derangement are higher in patients with co-morbid conditions.

Distúrbios ácido-base nas doenças hepáticas / Acid-base disorders in liver diseases

O objetivo deste artigo foi abordar as controvérsias científicas acerca dos distúrbios ácido-base nas doenças hepáticas. Nos estágios avançados da doença hepática, os distúrbios ácido-base atuam de forma complexa, comprometendo a qualidade de vida do paciente e desafiando o manejo clínico. A literatura apresenta a alcalose respiratória como uma das principais alterações, porém há uma longa discussão sobre o mecanismo fisiopatológico; em especial, citam-se a hipóxia, a hipocapnia e o nível de progesterona. Nas desordens metabólicas, com destaque para a acidose, os estudos apontam principalmente o lactato, os unmeasured ions ou íons não medidos e as alterações hidroeletrolíticas, mas cada componente desse sobressai-se dependendo da fase da doença estudada, compensada ou descompensada. As controvérsias dos distúrbios ácido-base nas doenças hepáticas devem-se ora à complexidade da fisiopatologia da própria doença, ora à necessidade de mais estudos esclarecedores.

The aim of this study is to address the scientific controversy about acid-base disorders in liver diseases. In the end stage of liver diseases, the acid-base disorder has a complex performance, impairing the patient's quality of life and challenging the clinic management. Although the literature shows respiratory alkalosis as one of the main alterations, there is a long discussion about the pathophysiological mechanism, specially regarding hypoxia, hypocapnia, and progesterone level. In metabolic disorders, especially acidosis, the studies mainly indicate the lactate, unmeasured ions, and hydroelectrolytic alterations, but, depending on the disease phase, either compensated or decompensated, each element has a particular action. The controversy about acid-base disorders in liver diseases is associated with the complexity of this condition, as well as with the necessity of more specialized research.

Demographic variation of electrolyte imbalance in a tertiary care pediatric intensive care unit

Background: Electrolyte imbalances are common in critically ill paediatric patients. When present, they can significantly affect the outcome. Critical care provision through Paediatric Intensive Care Units (PICU) is aimed at maintaining 'homeostasis' in the body which is vital for the organ's support and optimal function. This involves fluids and electrolytes balance.Methods: This prospective observational study was conducted in the PICU, SCB MC and Hospital, Cuttack during November 2015 to October 2017. includes Children admitted to PICU (Based on consensus guidelines for PICUs in India, Indian Society of Critical Care Medicine (Pediatric Section) and Indian Academy of Pediatrics (Intensive Care Chapter).Results: Percentage of male children was 65.9%, with male to female ratio 1.9:1, showing male dominance. Most electrolyte imbalances were seen in age group of 1 to 5 years (67.06%). Abnormal serum electrolyte was seen in 37.91% in our study. SIADH was observed in 43.5% of euvolemic hyponatremic patients. SIADH was observed in 27.8% of hyponatremic patients. Respiratory disorder was the most common attributing factor for SIADH followed by CNS disorder.Conclusions: The present study showed high incidence of electrolyte abnormalities in patients admitted to pediatric intensive care unit. Though at times symptoms of electrolyte disorder is indistinguishable from symptoms of primary pathology, so a close monitoring and correction of electrolyte abnormalities is necessary for better outcome. SIADH is recognizable and common cause of electrolyte imbalance in PICU. Thus, this study recommends early routine monitoring of serum electrolytes in all patients admitted to PICU.

A study of mortality and morbidity profile of electrolyte imbalance in critically ill children with special importance to mechanical ventilation

Background: Electrolytes imbalance is not uncommon in critically ill children. The outcome of critically ill child is dependent on various factors like the underlying disease, fluid and nutrition, which are responsible for electrolyte homeostasis in tandem with renal function and many others. In this study authors look into morbidity and mortality associated with dyselectrolytemia with special importance to children on mechanical ventilation.Methods: This prospective observational study was conducted in the PICU, SVPPGIP (SCB MC and Hospital), Cuttack during the period November 2015 to October 2017. Includes children admitted to PICU (Based on consensus guidelines for PICUs in India, Indian Society of Critical Care Medicine (Pediatric Section) and Indian Academy of Pediatrics (Intensive Care Chapter).Results: Mortality distribution in electrolyte abnormality patients is 27.9% (around 3 times higher than normal electrolyte patients). 25% hyponatremic patients and 31.25% hypernatremia patients expired, 30.76% hypokalemia patients, 32.72% hyperkalemia patients expired. Morbidity distribution in electrolyte imbalance population was 85.27%, with more than 7 days of stay in PICU. Amongst the mechanical ventilated patient, 54.23% patients having potassium disturbances were associated with significant mortality and morbidity. No such significant relation exists between mechanical ventilation and dyselectrolytemia of sodium and calcium.Conclusions: Early recognition with a thorough understanding of common electrolyte abnormalities and their prompt management definitely pose an implication on the final outcome of the patient. Aggressive and strict adherence to correction of in particular to potassium before weaning is necessary for successful weaning from ventilator.

Sobrecarga hídrica em crianças submetidas à ventilação mecânica / Fluid overload in children undergoing mechanical ventilation

RESUMO Os pacientes admitidos em uma unidade de terapia intensiva estão sujeitos à sobrecarga fluídica acumulada e recebem volume endovenoso pela ressuscitação agressiva, preconizada nas recomendações de tratamento do choque séptico, além de outras fontes de líquidos relacionadas às medicações e ao suporte nutricional. A estratégia liberal de oferta hídrica tem sido associada a maiores morbidade e mortalidade. Apesar de haver poucos estudos prospectivos pediátricos, novas estratégias estão sendo propostas. Esta revisão não sistemática discute a fisiopatologia da sobrecarga fluídica, suas consequências e as estratégias terapêuticas disponíveis. Durante a síndrome da resposta inflamatória sistêmica, o glicocálice endotelial é danificado, favorecendo o extravasamento fluídico, traduzido em edema intersticial. O extravasamento para o terceiro espaço se traduz em maior tempo de ventilação mecânica, maior necessidade de terapia de substituição renal e mais tempo de internação na unidade de terapia intensiva e no hospital, entre outros. A monitorização hemodinâmica adequada, bem como a infusão cautelosa de fluídos, pode minimizar estes danos. Uma vez instalada a sobrecarga fluídica acumulada, o tratamento com o uso crônico de diuréticos de alça pode levar a uma resistência ao uso destas medicações. A utilização precoce de vasopressores (norepinefrina) para melhora do débito cardíaco e perfusão renal, a associação de diuréticos e uso da aminofilina para indução de diurese, e a utilização de protocolos de sedação e mobilização precoce são algumas estratégias que podem reduzir morbimortalidade na unidade de terapia intensiva.

ABSTRACT Patients admitted to an intensive care unit are prone to cumulated fluid overload and receive intravenous volumes through the aggressive resuscitation recommended for septic shock treatment, as well as other fluid sources related to medications and nutritional support. The liberal liquid supply strategy has been associated with higher morbidity and mortality. Although there are few prospective pediatric studies, new strategies are being proposed. This non-systematic review discusses the pathophysiology of fluid overload, its consequences, and the available therapeutic strategies. During systemic inflammatory response syndrome, the endothelial glycocalyx is damaged, favoring fluid extravasation and resulting in interstitial edema. Extravasation to the third space results in longer mechanical ventilation, a greater need for renal replacement therapy, and longer intensive care unit and hospital stays, among other changes. Proper hemodynamic monitoring, as well as cautious infusion of fluids, can minimize these damages. Once cumulative fluid overload is established, treatment with long-term use of loop diuretics may lead to resistance to these medications. Strategies that can reduce intensive care unit morbidity and mortality include the early use of vasopressors (norepinephrine) to improve cardiac output and renal perfusion, the use of a combination of diuretics and aminophylline to induce diuresis, and the use of sedation and early mobilization protocols.

Enteral fluid therapy in neonatal calves and features of commercially available electrolyte solutions in Brazil / Hidratação enteral em bezerros neonatos e características das soluções eletrolíticas disponíveis comercialmente no Brasil

ABSTRACT: According to the World Health Organization, the development of orally replacement fluids and electrolytes was one of the most significant advances of the twentieth century, markedly reducing mortality from diarrheal children. In veterinary medicine, oral electrolyte solutions (OES) are routinely used to treat diarrheic neonatal calves in order to correct water, electrolyte and acid base imbalances. In North America, the use of OES is routine and there are at least 20 commercial alternatives. Use of OES has increased in recent years in Brazil, but just five commercial products are currently available. The OES should contain, in suitable concentrations, electrolytes, glucose and an alkalizing agent to ensure its therapeutic efficacy. This review aimed to address the therapeutic importance of OES for neonatal calves and to evaluate the compositions and characteristics of those commercially available in Brazil.

RESUMO: De acordo com a Organização Mundial da Saúde, o desenvolvimento da reposição de fluidos e eletrólitos por via oral foi um dos avanços mais significativos da medicina no século XX, reduzindo marcadamente a mortalidade de crianças diarreicas. Na medicina veterinária, as soluções eletrolíticas orais (SEO) são rotineiramente utilizadas no tratamento de bezerros neonatos diarreicos com o intuito de corrigir os desequilíbrios hidroeletrolíticos e ácido base. Na América do Norte, o emprego de SEO é habitual e existem, pelo menos, 20 alternativas comerciais. O uso das SEO se expandiu nos últimos anos, no Brasil, havendo, atualmente, cinco produtos disponíveis no comércio. As SEO devem veicular eletrólitos, glicose e um agente alcalinizante em concentrações apropriadas para garantir a sua eficácia terapêutica. Essa revisão tem o objetivo de abordar a importância e uso terapêutico das SEO para bezerros neonatos, além de avaliar as composições e características das disponíveis comercialmente no mercado brasileiro.

The clinical comparative study on the therapeutic effects of NICU patients implemented by NICU professional doctors and non-NICU professional doctors / 天津医药

Objective To explore the implementation styles on the therapeutic effects on the neurosurgical intensive care unit (NICU) patients. Methods Patients were enrolled during February 3, 2015 to February 3, 2016. The key point time was August 3, 2015 when the treatment in our NICU was fully implemented by NICU professional doctors. Based on this time point, all the enrolled patients were divided into non-NICU professional doctor implementing (NNPDI) group and NICU professional doctor implementing (NPDI) group. Thus non-NICU professional doctors and professional doctors were the leaders of diagnosis and treatment in tow groups. The length of hospital stay, complications, prognosis and other therapeutic outcomes were compared between two groups. Results The length of hospital stay was longer in NPDI group than that in NNPDI group (P0.05). The proportion of referral to other wards and fatality rate were both lower in NPDI group than those in NNPDI group (P0.05). Conclusion The NICU professional doctor implementing may be contribute to, at least in part, the improving of prognosis of NICU patients without obvious advantages in most complications. The level of professional management remains to be improved.

Electrocardiogram analysis of 339 patients with abnormal blood potassium / 中国医师进修杂志

Objective To research the electrocardiogram (ECG) manifestations of common electrolyte disturbance and to discuss the accuracy of ECG diagnosis. Methods One hundred and sixty-nine hospitalized patients with hyperkalemia and 170 patients with hypokalemia were selected and the results of ECG were analyzed. Results In mild hyperkalemia patients (serum potassium concentration 5.5- 6.5 mmol/L), the ECG abnormal rate was 91.4% (64/70). In mild hypokalemia patients (serum potassium concentration 3.0-3.5 mmol/L), the ECG abnormal rate was 56.9% (41/72). There was significant difference (P < 0.05). The greater the deviation of serum potassium concentration, the more obvious the characteristic changes of ECG. Conclusions In addition to the blood biochemical test, ECG is also a kind of check tool that can help to diagnose abnormal blood potassium.

Ajustes Cardiovasculares Induzidos pela Desidratação Crônica nas Fases Iniciais do Período Pós-Natal em Ratos Acordados / Cardiovascular Adjustments Induced by Chronic Dehydration in the Early Stages of PostNatal in Awake Rats

Alterações da osmolaridade do compartimento extracelular podem alterar o volume, o metabolismo e a função celular. Em virtude disso,varias complicações podem ser observadas, dentre elas a hipertensão arterial. Assim, a regulação precisa do volume e da osmolaridade docompartimento extracelular é fundamental para a manutenção das funções normais do organismo e da sobrevivência. O objetivo desse estudofoi avaliar os parâmetros hemodinâmicos através de desidratação induzida por furosemide em ratos jovens não anestesiados. Foram utilizados,ratos Wistar com cinco dias de idade, divididos em dois grupos experimentais, um controle (n=10) e um submetido ao tratamento comFurosemide (10mg/kg de massa corpórea, n=12), administrado três vezes por semana, durante dois meses. Após o tratamento, os animaisforam anestesiados para cateterização com cânulas inseridas na artéria e veia femorais, através de um corte inguinal de um dos lados. Ascânulas foram transpassadas subcutaneamente através do dorso do animal e foram exteriorizadas. Os experimentos foram realizados apósuma recuperação de 48h do procedimento cirúrgico, utilizando um amplificador e um software. Os resultados obtidos demonstraram que nãohouve diferenças nos testes induzidos de ingestão de água durante os 120 minutos analisados, quando comparados o grupo controle e o grupofurosemide, respectivamente. Na análise da pressão arterial méia e frequência cardíaca, não foi observada modificação dos níveis basais. Essepadrão de resposta também foi obtido quando analisado a PAS e PAD. Com esses resultados, concluímos que a depleção do compartimentoextracelular induzido pela administração de furosemide em ratos jovens não é fator determinante para alteração dos parâmetros hemodinâmicosna fase adulta.

Changes in osmolarity of the extracellular compartment may change the volume, metabolism and cellular function. As a result, manycomplications can be observed, among them hypertension. Thus, precise regulation of the volume and osmolality of the extracellularcompartment is critical to maintaining normal body functions and survival. Previous results demonstrated that despite anesthetized ratssubmitted to chronic diuretic treatment showed no change in sensitivity to sodium and water, an increased arterial pressure was observed. Thepresent study aims to assess hemodynamic parameters through furosemide-induced dehydration in anaesthetized young rats. Five days oldWistar rats divided into two groups, a control (n = 10) and a group subjected to subcutaneous treatment with the diuretic Furosemide (10mg/kg of body weight, n = 12) were used. After treatment, the animals were anesthetized for the implantation of the polyethylene tubes, which wereinserted into the artery (for records cardiovascular variables) and femoral vein through a cut inguinal one side (left / right). The cannulaswere transfixed subcutaneously through the back of the animal and were exteriorized. Data were recorded after a 48h recovery of the surgicalprocedure, using an amplifier and software. No differences in induced intake test of water within 120 minutes were observed. With respect tomean arterial pressure and heart rate, no modification on baseline levels were observed (PAM: 99.4 ± 1.9 mmHg, control vs 102.7 ± 1 mmHg,furosemide; FC: 362.5 ± 5.2 bpm, control vs 364.9 ± 7 bpm, furosemide). This response pattern was also obtained for SBP (124.3 ± 6 mmHg,control vs 130 ± 1.6 mmHg, furosemide) and DBP (82.2 ± 1.9 mmHg, control vs 82.1 ± 1 mmHg, furosemide). We concluded that depletionof the extracellular compartment induced by furosemide administration in young rats is not a determining factor to change the hemodynamicparameters in adulthood.

Objective To explore the prevalence and the relative factors of the overweight and the obese in a population of Gansu Province pre-pregnancy women.and the effects of pre-pregnancy maternal body mass index (BMI) on gestational weight gain and pregnant outcome.Methods We conducted a populationbased birth cohort study in Gansu Province Maternity and Child Health Care Hospital from February,2010 to December,2011.Single live term birth women who have complete anthropometry were enrolled this study.They were categorized into four BMI groups according to World Health Organization's BMI recommendations for Asian populations.We explored the prevalence and the relative factors of the overweight and the obese,and the effects of pre-pregnancy maternal body mass index on gestational weight gain and birth outcomes by Chi-square test,analysis of variance.Results A total of 6 400 cases included in this study.The BMI range is from 13.3 to 38.1,the average BMI is (20.6 ±2.7).Among 6 400 cases,636 cases(9.9％) and 416 cases (6.5％) were overweight and obese.The average age (unit:years) is increase gradually in low weight group (27.8±3.8),normal group (29.1 ±4.3),overweight group (30.3 ±4.7) and obese group (30.6±4.6),the difference was statistically significant (F=77.490,P＜0.01).The result prompt that the median BMI increased with the increasing of maternal age (r=0.18,P＜0.01).The BMI of multiparous women (21.22 ±2.63) is higher than nulliparous women (20.43 ± 2.64),the difference was statistically significant (t=-9.630,P＜0.01).The BMI has negatively correlated with education level and economic income level (r=-0.06,P＜0.01; r=-0.04,P=0.036).With the increase of BMI,the weight gain of early (13 weeks) pregnancy (F=8.892,P＜ 0.01) and the total weight gain during whole pregnancy (F=21.700,P＜ 0.01) gradually reduced in four groups.The neonatal birth weight in overweight group is largest,in turn higher than obesity group,normal group and low weight group,the difference was statistically significant (F=11.261,P＜0.01).With increasing BMI,the incidence of pre eclampsia (x2=85.758,P＜0.05),gestational diabetes mellitus (x2=58.913,P＜0.05),postpartum hemorrhage (x2=13.501,P＜0.05),neonatal hypoglycemia (x2=6.563,P＜0.05) and neonatal pulmonary hyaline membrane (x2=9.579,P＜0.05) was increased.The incidence of caesarean section (x2=125.442,P＜0.05),macrosomia (x2=62.963,P＜0.05) and birth defects (x2=9.087,P＜0.05) also increased.The incidence of abnormal umbilical cord in overweight group is highest,in turn higher than normal group,low weight group,and the obesity group (x2=15.82g,P=0.001).The incidence of neonatal electrolyte disorder in obesity group was higher than low weight group,normal group,and the overweight group (x2=12.092,P=0.007).The incidence of preterm birth in overweight group is highest,in turn higher than obesity group,normal group and the low weight group (x2=7.865,P=0.049).Compared with the normal group,the risk of caesarean section (OR=l.700,95％ CI:1.325-2.181),pre-eclampsia (OR=2.436,95％ CI:1.578-3.761),gestational diabetes (OR=3.182,95％ CI:1.049-9.653) and abnormal umbilical cord (OR=2.252,95％ CI:1.267-4.004) in overweight group was increased.the risk of pre eclampsia (OR=2.585,95％ CI:1.020-6.914),macrosomia (OR=2.484,95％ CI:1.017 6.070),neonatal electrolyte disorder (OR=4.430,95％ CI:1.290-t5.217) in obesity group was increased.Conclusions The median BMI before pregnancy increased with increasing maternal age,parity,but decreased with education level and income level.The weight gain of early (13 weeks) pregnancy and the total weight gain during whole pregnancy decreased with increasing BMI.Overweight and obesity before pregnancy increased the risk the caesarean section,preeclampsia,gestational diabetes,macrosomia and neonatal electrolyte disorder.

Factors Precipitating Hypokalemia in Diabetic Patients: A Cross Sectional Study.

Background: Hypokalemia is a very common electrolyte imbalance in diabetic patients which leads to substantial morbidity and mortality. Severe hypokalemia is associated with lifethreatening arrhythmias and sudden cardiac death. There are no adequate studies regarding the incidence and factors precipitating hypokalemia in Bangladeshi diabetic subjects. Objective: The objective of this study was to find out the factors precipitaing hypokalemia in diabetic patients. Materials and Methods: A total 95 admitted diabetic patients with hypokalemia were studied. Specimens were collected from all adult diabetic patients with serum potassium level <3.5 mmol/L irrespective of cause of admission. Informations were obtained in a semistructured data collection form and analyzed. Results: Most of the subjects (61.1%) belonged to the age group of 60 years and above, 31.5% to the age group 40–59 years and 7.4% belonged to the age group of 20–39 years. Sixty one (64.2%) patients were females and 34 (35.8%) were males. In 63.2% cases, vomiting was found as a factor causing hypokalemia in the diabetic patients. Other common factors precipitaing hypokalemia were diarrhea (42.1%), inadequate diet (9.5%), severe hyperglycemia (3,2%), diabetic ketoacidosis (6.3%) and drugs especially diuretics (18.9%), bronchodilators (6.3%) and steroids (5.3%). The commonest comorbidity associated with diabetes was hypertension. Conclusion: In this study the commonest precipitating factor causing hypokalemia was vomiting. Majority of hypokalemic patients were female and of older age group. When hypokalemia is identified, the underlying precipitating factor should be sought and the disorder treated. Diuretics should be used with caution in the elderly patients having hypertension, a common comorbid condition of diabetes, as these patients are susceptible to develop hypokalemia.
