Challenges Faced in Managing an Adult Uncorrected Tetralogy of Fallot Patient with Pneumonia and Septic Shock in the Intensive Care Unit.

Tetralogy of Fallot (TOF) is the most common form of cyanotic congenital heart disease. We present a 61-year-old uncorrected TOF patient who presented with sepsis and acute respiratory failure. At presentation, the patient had tachypnea, tachycardia, and oxygen saturation (SpO2) 64%. Chest X-ray (CXR) showed bilateral basal opacities. 2D echo revealed left ventricular dysfunction, infundibulum stenosis, pulmonary atresia, overriding of the aorta, and ventricular septal defect. A provisional diagnosis of community-acquired pneumonia with septic shock with uncorrected TOF was made. He received empirical antibiotics, ventilatory support, and supportive care. Ventilator weaning was done accepting an arbitrary baseline SpO2 of 70-75% and lactate-guided volume resuscitation led to a successful outcome. Coronary angiogram showed collaterals. This case report illustrates the dilemmas faced in treating a critically ill uncorrected TOF. To the best of our knowledge, this case could be the oldest surviving uncorrected TOF patient in the Indian population. HOW TO CITE THIS ARTICLE: Prakash SY, Kartik M, Rao M, Harde YR.

A Survey on Workplace Violence Experienced by Critical Care Physicians.

INTRODUCTION: Workplace violence (WPV) has been defined as, "violent acts including physical assault and threats of assault directed toward personnel at work or on duty". Healthcare staff are at highest risk of WPV among the professionals and it is more common among the critical care services. Prevalence of WPV among doctors all over the world is around 56-80% and in Indian scenario, it is around 40.8-75%. There is scarcity of studies on WPV among doctors from India. To our knowledge, this is the first of its kind survey conducted to know about the incidence of WPV amongst critical care physicians in India. MATERIALS AND METHODS: This survey was conducted after taking due ethical committee clearance amongst critical care physicians attending a critical care conference. The purpose of the study was informed to the participants and a pretested, self-administered, semi-structured questionnaire was distributed among them for their voluntary and anonymous response. RESULTS: Out of 160 delegates who were given the questionnaire, 118 responses were collected and their forms were analyzed. Maximum responses (84%) received were of age group 20-40 years. Seventy-two percent respondents experienced WPV during their work hours. Most common type of violence reported was verbal violence (67%). Sixty-five percent respondents reported that poor communication was the leading cause of WPV. Due to WPV, most of the respondents (60%) had to change their place and pattern of work. Proper communication (76%) was the most common measure among multiple measures suggested by respondents for avoiding WPV. Eighty-three (98%) respondents opined that conflict management should be part of regular curriculum in medical education. CONCLUSION: Improving the communication skills amongst critical care physicians, teaching doctors about conflict management in their regular curriculum of medical education, spreading awareness in public about patient rights and taking initiatives in propagating an idea to "Fight against the diseases and not against the doctors" are the key measures to combat WPV.

Acute respiratory failure in scrub typhus patients.

Respiratory failure is a serious complication of scrub typhus. In this prospective study, all patients with a diagnosis of scrub typhus were included from a single center Intensive Care Unit (ICU). Demographic, clinical characteristics, laboratory, and imaging parameters of these patients at the time of ICU admission were compared. Of the 55 scrub typhus patients, 27 (49%) had an acute respiratory failure. Seventeen patients had acute respiratory distress syndrome, and ten had cardiogenic pulmonary edema. Respiratory supported patients were older had significant chronic lungs disease and high severity illness scores (Acute Physiology and Chronic Health Evaluation-II and Sequential Organ Failure Assessment score). At ICU admission, these patients presented with more deranged laboratory markers, including high bilirubin, high creatine kinase, high lactate, metabolic acidosis, low serum albumin, and presence of ascites. The average ICU and hospital stay were 4.27 ± 2.74 and 6.53 ± 3.52 days, respectively, in the respiratory supported group. Three patients died in respiratory failure group, while only one patient died in nonrespiratory failure group.

Prone position and pressure control inverse ratio ventilation in H1N1 patients with severe acute respiratory distress syndrome.

AIM: To observe the 28 and 90 days mortality associated with prone position and assist control-pressure control (with inverse ratio) ventilation (ACPC-IRV). MATERIALS AND METHODS: All patients who were admitted to our medical Intensive Care Unit (ICU) who are positive for H1N1 viral infection with severe acute respiratory distress syndrome (ARDS) and requiring invasive mechanical ventilation in prone position were included in our prospective observational study. Six patients who are positive for H1N1 required invasive ventilation in prone position. These patients were planned to ventilate in prone for 16 h and in supine for 8 h daily until P/F ratio >150 with FiO2 of 0.6 or less and positive end-expiratory pressure <10 cm of H2 O. RESULTS: At admission, among these six patients the mean tidal volume generated was about 376.6 ml which was in the range of 6-8 ml/kg predicted body weight. The mean lung injury score was 3.79, mean PaO2 /FiO2 ratio was 52.66 and mean oxygenation index was 29.83. The mean duration of ventilation was 9.4 days (225.6 h). The ICU length of stay was 11.16 days. There was no mortality at 28 and 90 days. CONCLUSION: Early prone combined with ACPC-IRV in H1N1 patients having severe ARDS can be used as a rescue therapy and it should be confirmed by large observational studies.

Optic nerve sheath diameter as a marker for evaluation and prognostication of intracranial pressure in Indian patients: An observational study.

BACKGROUND AND AIMS: The aim was to evaluate efficacy of optic nerve sheath diameter (ONSD) by ultrasound as a noninvasive method for detecting raised intracranial pressure (ICP) in intensive care unit, to compare with computed tomography/magnetic resonance imaging (MRI) findings of raised ICP and to prognosticate ONSD value with treatment. MATERIALS AND METHODS: We conducted a prospective, observational study on 101 adults by including 41 healthy individuals in group A as control and 60 patients in group B admitted with fever, headache, vomiting, and altered sensorium. We examined them in supine position using 10 MHz linear array probe on closed eyelid. ONSD was measured 3 mm behind the globe in each eye. A mean binocular ONSD > 4.6 mm in female and 4.8 mm in male was considered abnormal. Midline shift, edema, effacement or ONSD > 5.0 mm on T2 MRI suggestive of elevated ICP was used to evaluate ONSD accuracy. RESULTS: Group A mean ONSD was 4.6 mm in females and 4.8 mm in males. Group B mean ONSD for 17 females was 5.103 ± 0.6221 mm (P = 0.002) and for 43 males 5.081 ± 0.5799 mm (P = 0.032). Radiological sign of raised ICP was confirmed in 35 patients (females = 11 and males = 24) with high ONSD value. Sensitivity of detecting raised ICP by ONSD was 84.6% in females and 75% in males while specificity was 100% in both genders. Out of 25 patients without radiological signs of raised ICP 10 patients showed high ONSD (females = 4.735 mm and males = 4.907 mm). ONSD was well prognosticated with treatment modalities. CONCLUSION: Bedside ocular ultrasonography for measuring ONSD can be used an early test for diagnosing raised ICP as it is a noninvasive, cost effective bedside test, which can be repeated for re-evaluation.
