Preoperative Ultrasonographic Evaluation of Subclavian Vein and Inferior Vena Cava for Predicting Hypotension Associated with Induction of General Anesthesia.

Introduction: Induction of general anesthesia is often associated with hypotension and is a common scenario faced by anesthesiologists. Intraoperative hypotension can have detrimental effects and cause various adverse effects leading to an extended hospital stay. Patients' preinduction volume status can have an effect on postinduction blood pressure. Ultrasonography is a useful tool for measuring intravascular volume status. We studied the ability of ultrasonographic measurement of subclavian vein (SCV) and inferior vena cava (IVC) diameter, collapsibility index (CI) to predict hypotension after induction of general anesthesia. Materials and Methods: We included 120 patients in our study. SCV measurements during spontaneous and deep inspiration and IVC measurements were taken before induction and postinduction blood pressure was monitored. Patients with mean arterial blood pressure <60 mmHg or with a 30% decrease from baseline were considered to be having hypotension. Results: The CI of IVC with a cutoff 37% showed sensitivity of 94% and specificity of 84% which was statistically significant. The CI of 36% of SCV during deep breathing was found to have high sensitivity and specificity of 90% and 87%. Conclusion: Our study in spontaneously breathing preoperative patients shows that SCV CI in deep breathing and IVC CI is very sensitive and reliable in predicting postinduction hypotension. Bedside ultrasound measurements can be easily done to obtain valuable information to recognize patients who could be at risk from postinduction hypotension.

Family Satisfaction in a Medical College Multidisciplinary Intensive Care Unit (ICU)-How Can We Improve?

BACKGROUND AND AIMS: In recent years, patient and family-centered implications are being recognized as important outcome measures and one of the quality indicators of health care system worldwide. Most of the Intensive Care Unit patients cannot make decisions themselves, accordingly family members are surrogate decision-makers and judges of care quality. This study was conducted as a prospective observational study using Family Satisfaction-Intensive Care Unit questionnaire to ascertain the level of family satisfaction of care and their involvement in the decision making process of their patient's treatment. MATERIALS AND METHODS: The study was conducted over 3 months with 100 family members by FS-ICU questionnaire survey method. After 48 hours of ICU admission, the questionnaire was administered to an eligible family member by a resident who was not involved in the treatment of the patient, in a language understood by them (English/Kannada). Each question was scored using 5 point Likert response Scale and the scores were transformed into 0 (least satisfied) to100 (most satisfied) scale. RESULTS: Satisfaction with overall care was 65.31±23.62 (FS-ICU/Care). Satisfaction with decision making process was 73.06±22.154 (FS-ICU/ DM). Individual factors which contributed to lower scores were management of pain and agitation of the patient, waiting room atmosphere and emotional support. CONCLUSION: This study identified the individual factors which contributed to the high and low satisfaction scores. With this baseline data as reference, there is scope to enhance the aspects of quality care for patients and their family members. HOW TO CITE THIS ARTICLE: JanardhanIyengar SM, Srinivasan R et al.

Point-of-Care Ultrasound to Evaluate Thickness of Rectus Femoris, Vastus Intermedius Muscle, and Fat as an Indicator of Muscle and Fat Wasting in Critically Ill Patients in a Multidisciplinary Intensive Care Unit.

BACKGROUND: Muscular atrophy is the universal feature in patients with ICUAW. Muscles of the lower limb are more prone to early atrophy. Measurement of fat thickness is used to assess malnutrition. This study was designed to evaluate if, subcutaneous fat also reduces along with muscle thickness and if it can be reliably used as an indicator of nutritional assessment in critically ill patients using point of care ultrasound. MATERIALS AND METHODS: An observational clinical study of 100 patients admitted to multidisciplinary intensive care units (ICUs). Total anterior thigh thickness, thickness of the rectus femoris muscle, fat thickness, and the combined thickness of vastus intermedius and rectus femoris were taken on day 1, 3, and 7 of ICU admission. RESULTS: There was progressive loss of muscle mass from day 1 to day 7. Muscle loss was not only limited to rectus femoris, but vastus intermedius also showed a significant decrease as indicated by the bone to muscle measurement. Skin to bone measurement which includes both muscle and fat compartment showed a decline. CONCLUSIONS: There is potential utility of ultrasound for early detection and probable corrective measures to prevent ICUAW. The rectus femoris thickness, skin to bone, and bone to muscle thickness show statistically significant difference on day 3, day 7 compared to day 1. Fat layer did not show statistically significant decrease.
