Purpose To correlate clinical indicators of peripheral perfusion with visceral organ vascular tone in 30 septic shock patients. Materials and Methods In a prospective pilot study, capillary refill time, the Mottling score, and peripheral temperature were determined within 24, 48, and 72 hours after intensive care unit admission. Simultaneously, pulsatility indices in the liver, spleen, kidneys, and intestines were measured by Doppler ultrasonography. Correlation analyses were calculated, applying an adjusted significance level (P< .0125) to correct for multiple testing. Results Significant relationships were observed between the pulsatility index of selected organs and the capillary refill time (intestines: r= 0.325, P= .007), and the Mottling score (kidneys: r= 0.396, P= .006), but not peripheral temperature (all r< 0.14, P> .05). An association over time was observed for the capillary refill time and pulsatility index of the liver (P= .04) and intestines (P= .03) as well as for the Mottling score and the kidneys' pulsatility index (P= .03), but not for peripheral temperature and any visceral organs' pulsatility index. Conclusions Capillary refill time and skin mottling may be correlated with the pulsatility index, a sonographic surrogate of vascular tone, of visceral organs in early septic shock.

INTRODUCTION:Liberal and overaggressive use of vasopressors during the initial period of shock resuscitation may compromise organ perfusion and worsen outcome. When transiently applying the concept of permissive hypotension, it would be helpful to know at which arterial blood pressure terminal cardiovascular collapse occurs. METHODS:In this retrospective cohort study, we aimed to identify the arterial blood pressure associated with terminal cardiovascular collapse in 140 patients who died in the intensive care unit while being invasively monitored. Demographic data, co-morbid conditions and clinical data at admission and during the 24 hours before and at the time of terminal cardiovascular collapse were collected. The systolic, mean and diastolic arterial blood pressures immediately before terminal cardiovascular collapse were documented. Terminal cardiovascular collapse was defined as an abrupt (<5 minutes) and exponential decrease in heart rate (> 50% compared to preceding values) followed by cardiac arrest. RESULTS:The mean ± standard deviation (SD) values of the systolic, mean and diastolic arterial blood pressures associated with terminal cardiovascular collapse were 47 ± 12 mmHg, 35 ± 11 mmHg and 29 ± 9 mmHg, respectively. Patients with congestive heart failure (39 ± 13 mmHg versus 34 ± 10 mmHg; P = 0.04), left main stem stenosis (39 ± 11 mmHg versus 34 ± 11 mmHg; P = 0.03) or acute right heart failure (39 ± 13 mmHg versus 34 ± 10 mmHg; P = 0.03) had higher arterial blood pressures than patients without these risk factors. Patients with severe valvular aortic stenosis had the highest arterial blood pressures associated with terminal cardiovascular collapse (systolic, 60 ± 20 mmHg; mean, 46 ± 12 mmHg; diastolic, 36 ± 10 mmHg), but this difference was not significant. Patients with sepsis and patients exposed to sedatives or opioids during the terminal phase exhibited lower arterial blood pressures than patients without sepsis or administration of such drugs. CONCLUSIONS:The arterial blood pressure associated with terminal cardiovascular collapse in critically ill patients was very low and varied with individual co-morbid conditions (for example, congestive heart failure, left main stem stenosis, severe valvular aortic stenosis, acute right heart failure), drug exposure (for example, sedatives or opioids) and the type of acute illness (for example, sepsis).

BACKGROUND:In this prospective, observational study, the rate of antibiotic resistance in cultures sampled from sepsis patients was determined in an intensive care unit of a low-middle income country.METHODS:Critically ill patients suffering from bacterial sepsis were eligible for enrollment. Aside from demographic, disease-related and sepsis-specific parameters, the type of microbiological sample and cultured microorganism as well as the resistance pattern (extensively resistant bacteria, multi-drug resistant bacteria) were documented. Descriptive statistical methods, parametric and non-parametric tests were used.RESULTS:215 sepsis patients were included. 193 ofthe 410 cultured organisms (47.1%) showed antibiotic resistance [extensively resistant bacteria, n = 90 (11%); multi-drug resistant bacteria, n = 103 (25.1%)]. 51.6% of the patients were infected by > or = 1 resistant bacteria. Bacteria with an exceptionally high rate of antibiotic resistance were Acinetobacter baumannii (90%), Enterobacter spp (60%) and coagulase-negative Staphylococci (60%). Patients infected with resistant bacteria more often received inadequate empirical antibiotic therapy (36.9 vs. 13.5%, p < 0.001), required mechanical ventilation (66.7 vs. 42.3%, p < 0.001) and renal replacement therapy (28.8 vs. 9.6%, p < 0.001) more frequently, and had a longer stay in the intensive care unit [5 (3-9.5) vs. 5 (2-8)%, p < 0.001] than patients with sepsis due to non-resistant bacteria. There was a trend towards a higher mortality in patients with resistant bacteria (43.2 vs. 31.7%, p = 0.09).CONCLUSION:Resistant bacteria were detected in up to 50% of microbiological samples from critically ill sepsis patients in the intensive care unit of a low-middle-income country. Antibiotic resistance appears to be a relevant problem of sepsis management in a resource-limited setting.

Objective To assess if secondary and tertiary hospitals in Mongolia have the resources needed to implement the 2008 Surviving Sepsis Campaign (SSC) guidelines.Methods To obtain key informant responses, we conducted a nationwide survey by sending a 74-item questionnaire to head physicians of the intensive care unit or department for emergency and critically ill patients of 44 secondary and tertiary hospitals in Mongolia. The questionnaire inquired about the availability of the hospital facilities, equipment, drugs and disposable materials required to implement the SSC guidelines. Descriptive methods were used for statistical analysis. Comparisons between central and peripheral hospitals were performed using non-parametric tests.Findings The response rate was 86.4% (38/44). No Mongolian hospital had the resources required to consistently implement the SSC guidelines. The median percentage of implementable recommendations and suggestions combined was 52.8% (interquartile range, IQR: 45.8-67.4%); of implementable recommendations only, 68% (IQR: 58.0-80.5%) and of implementable suggestions only, 43.5% (IQR: 34.8-57.6%). These percentages did not differ between hospitals located in the capital city and those located in rural areas.Conclusion The results of this study strongly suggest that the most recent SSC guidelines cannot be implemented in Mongolia due to a dramatic shortage of the required hospital facilities, equipment, drugs and disposable materials. Further studies are needed on current awareness of the problem, development of national reporting systems and guidelines for sepsis care in Mongolia, as well as on the quality of diagnosis and treatment and of the training of health-care professionals.

Study Objective: To evaluate the current status of anesthesia and its allied disciplines in Mongolia.Design: Nationwide questionnaire survey.Setting: Two university hospitals.Measurements: A total of 44 hospitals that include a department of surgery and that were registered at the Mongolian Ministry of Health were queried. The questionnaire included 44 questions in two sections. The first section consisted of 6 general questions about the hospital, and the second section included 40 questions on anesthesia and perioperative patient care. The Mann-Whitney U-test, Chi(2)-tests, and a bivariate correlation analysis were used for statistical analysis.Main Results: 44 (100%) questionnaires were returned. Twenty-two (50%) hospitals were located in the capital city of Ulaanbaatar. Nine hundred (median; interquartile range: 413-1,468) surgical interventions were performed annually in the study hospitals. Physician anesthesiologists delivered anesthesia in all hospitals. Techniques for general anesthesia included endotracheal intubation (95.5%), laryngeal mask ventilation (13.6%), mask ventilation (27.3%), dissociative ketamine anesthesia (84.1%), and combined general/regional anesthesia (63.6%). Regional anesthetic techniques included spinal (97.7%), epidural (43.2%), axillary plexus (40.9%), peripheral nerve (13.6%), and local anesthesia (15.9%). The most frequently used hypnotics were ketamine (86.4%) and thiopental sodium (70.5%). Halothane was available in all hospitals. Oxygen was available during anesthesia in 95.5% of hospitals. The most widely available intraoperative monitoring equipment were a stethoscope (84.1%), oximeter (81.8%), and sphygmomanometer (84.1%). A recovery room was available in 22 (50%) hospitals.Conclusions: Anesthesia is an underdeveloped and under-resourced medical specialty in Mongolia. (C) 2010 Elsevier Inc. All rights reserved.

PURPOSE:To evaluate intensive care resources, support, and personnel available in Mongolia's 3 largest cities.MATERIALS AND METHODS:This prospective study was performed as a questionnaire-based survey evaluating intensive care units (ICUs) in Mongolia's 3 main cities.RESULTS:Twenty-one of 31 ICUs participated in the survey. The median number of beds per ICU was 7 (interquartile ranges, 6-10) with 0.7 (0.6-0.9) physicians and 1.5 (0.6-1.8) nurses per bed. A 24-hour physician service was available in 61.9% of the participating ICUs. A median number of 359 patients (250-500) with an average age of 39 (30-49) years were treated annually. Oxygen was available in all ICUs, but only for 60% (17-75) of beds. Pressurized air was available in 33% of the ICUs for 24% (0-15) of beds. Of the ICUs, 52.4% had a lung ventilator serving 20% (0-23) of beds. The most common admission diagnoses were sepsis, stroke, cardiac disease, postoperative or postpartum hemorrhage, and intoxication. Availability of medical equipment, disposables, and drugs was inadequate in all ICUs.CONCLUSIONS:Intensive care medicine in Mongolia's 3 largest cities is an under-resourced and underdeveloped medical specialty. The main problems encountered are insufficient training of staff as well as lack of medical equipment, disposables, and drugs.

INTRODUCTION:Case reports are important instruments to describe rare disease conditions and give a rough estimation of their global incidence. Even though collected in international databases, most case reports are published by clinicians from industrialized nations and little is known about the incidence of rare cases in less developed countries, which are home to 75% of the world's population.CASE PRESENTATION:We present seven patients who suffered from diseases which are either considered to be rare or have not yet been described before according to international databases, but occurred during a 5-month period in one intensive care unit of a less developed country. During the observation period, patients with a spontaneous infratentorial subdural hematoma (Asian, female, 41 years), general exanthema and acute renal failure after diesel ingestion (Asian, male, 30 years), transient cortical blindness complicating hepatic encephalopathy (Asian, female, 49 years), Fournier gangrene complicating acute necrotizing pancreatitis (Asian, male, 37 years), acute renal failure due to acetic acid intoxication (Asian, male, 42 years), haemolytic uremic syndrome following septic abortion (Asian, female, 45 years), and a metal needle as an unusual cause of chest pain (Asian, male, 41 years) were treated. According to the current literature, all seven disease conditions are considered either rare or have so far not yet been reported.CONCLUSION:The global incidence of rare cases may be underestimated by contemporary international databases. Diseases which are currently considered to be rare in industrialized nations may occur at a higher frequency in less developed countries. Reasons may not only be a geographically different burden of certain diseases, limited diagnostic and therapeutic facilities, but also a relevant publication bias.

Background: Few data are available on intensive care unit (ICU) patient populations and critical care medicine practices in developing countries.Methods: This prospective study evaluated differences in patient characteristics, ICU practice, and outcome between the ICUs of a Mongolian 400-bed tertiary university hospital (MonICU) and an Austrian 429-bed secondary hospital (AutICU). Demographics, chronic health status, clinical parameters, disease and therapeutic severity scores, and outcome were documented for all patients admitted to the two ICUs during a period of four and a half months. Standard tests and multiple regression analysis were used for statistical analysis.Results: A total of 203 critically ill patients were admitted to MonICU and 257 to AutICU. MonICU patients had fewer chronic diseases than AutICU patients (0.9 +/- 0.8 vs. 2.7 +/- 1.5, P < 0.001) but more frequently suffered from tuberculosis (2.5% vs. 0%, P = 0.01) and more frequently had never been medically examined before ICU admission (10.8% vs. 0%, P < 0.001). Admission diagnoses differed both in type and relative proportions in the two ICUs (P < 0.001). Admission of MonICU patients was more frequently unplanned (69% vs. 50.2%, P < 0.001), and although disease was more severe in these patients they received fewer therapeutic interventions than the AutICU patients. Overall mortality was higher in the MonICU patients (19.7 vs. 6.2%, P < 0.001).Conclusions: Patient characteristics and ICU practices varied significantly between the two ICUs. Mortality was substantially greater at MonICU, particularly among patients suffering from multiple-organ dysfunction. Strategies to improve the care of critically ill patients at MonICU should address both system- and staff-related problems, improve acceptance of the ICU service among physicians of other disciplines and upgrade the training of ICU staff.
