Background: Endotracheal intubation has become the mainstay of modern anaesthesia due to various reasons like maintenance of patency of airway, prevention of pulmonary aspiration, providing positive pressure ventilation, predictable delivery of FiO2 and elimination of CO2. Stimulation of upper respiratory tract during tracheal intubation under general anaesthesia causes activation of sympatho-adrenal system and results in increased serum catecholamines.Aims and Objectives: To identify and compare the Haemodynamic responses contributed by each stage of nasotracheal with that of orotracheal intubation.Materials and Methods: About 125 patients in the age group 18-50 years, ASA physical status I-II of either sex, scheduled to undergo various elective surgical procedures requiring nasotracheal or orotracheal intubation were evaluated in the present study.After 4 minutes of ventilation, patients requiring nasal intubation (n=75) were allocated to three groups- nasopharyngeal intubation group (NPI), nasopharyngeal intubation with laryngoscopy group (NPIL) and nasotracheal intubation group (NTI). Those requiring oral intubation (n=50) were allocated to two groups namely- laryngoscopy only group (L) and laryngoscopy followed by orotracheal intubation group (OTI). Haemodynamic parameters like heart rate and blood pressure, SpO2, ECG, ETCO2 were monitored continuously and data were recorded before induction, just after induction and after intubation at one minute interval for five minutes.Results: The pre-induction and pre-procedure values of systolic, diastolic and mean arterial pressures and also heart rate were similar in each group (P<0.05). Induction of anaesthesia caused a significant decrease in systolic, diastolic and mean arterial pressures in all groups compared to their pre-induction values (P<0.0012). Our study showed that systolic, diastolic and mean arterial pressures were significantly increased after intubation procedures in all the five groups compared to pre-procedure values.Conclusion: All the procedures evoked cardiovascular responses characterized by increases in heart rate and blood pressure. NTI produced a significant rise in blood pressure.Asian Journal of Medical Sciences Vol.8(5) 2017 41-47

Abstract. A considerable number of behavioral and neuroscientific studies on insight problem solving have revealed behavioral and neural correlates of the dynamic insight process; however, somatic correlates, particularly somatic precursors of creative insight, remain undetermined. To characterize the somatic precursor of spontaneous insight, 22 healthy volunteers were recruited to solve the compound remote associate (CRA) task in which a problem can be solved by either an insight or an analytic strategy. The participants’ peripheral nervous activities, particularly electrodermal and cardiovascular responses, were continuously monitored and separately measured. The results revealed a greater skin conductance magnitude for insight trials than for non-insight trials in the 4-s time span prior to problem solutions and two marginally significant correlations between pre-solution heart rate variability (HRV) and the solution time of insight trials. Our findings provide the first direct evidence that spontaneous insight in problem solving is a somatically peculiar process that is distinct from the stepwise process of analytic problem solving and can be represented by a special somatic precursor, which is a stronger pre-solution electrodermal activity and a correlation between problem solution time and certain HRV indicators such as the root mean square successive difference (RMSSD).

Background and Objectives: Social interactions involving personal disclosures are ubiquitous in social life and have important relational implications. A large body of research has documented positive outcomes from fruitful social interactions with amicable individuals, but less is known about how self-disclosing interactions with inimical interaction partners impacts individuals. Design and Methods: Participants engaged in an immersive social interaction task with a confederate (thought to be another participant) trained to behave amicably (Fast Friends) or inimically (Fast Foes). Cardiovascular responses were measured during the interaction and behavioral displays coded. Participants also reported on their subjective experiences of the interaction. Results: Participants assigned to interact in the Fast Foes condition reported more negative affect and threat appraisals, displayed more negative behaviors (i.e., agitation and anxiety), and exhibited physiological threat responses (and lower cardiac output in particular) compared to participants assigned to the Fast Friends condition. Conclusions: The novel paradigm demonstrates differential stress and affective outcomes between positive and negative self-disclosure situations across multiple channels, providing a more nuanced understanding of the processes associated with disclosing information about the self in social contexts.
