Background and Aims:A high incidence of anxiety has been reported in patients in the operation theatre set up. We developed a short visual clip of 206 s duration depicting the procedure of spinal anaesthesia (SAB) and aimed to compare the effect of this video on perioperative anxiety in patients undergoing procedures under SAB.Methods:A prospective randomised study of 200 patients undergoing surgery under SAB was conducted. Patients were allotted to either the nonvideo group (Group NV - those who were not shown the video) or the video group (Group V - those who were shown the video). Anxiety was assessed using the Spielberger State-Trait Anxiety Inventory during the pre-anaesthetic check-up and before surgery. Haemodynamic parameters such as heart rate (HR) and mean arterial pressure (MAP) were also noted. Student's t-test was used for normally distributed and Mann–Whitney U-test for nonnormally distributed quantitative data. Chi-square test was used for categorical data.Results:Both groups were comparable with respect to baseline anxiety scores and haemodynamic parameters. The nonvideo group showed a significant increase in state anxiety scores before administration of SAB (P < 0.001). Patients in the video group had significantly lower HR and MAP preoperatively (P < 0.001). The prevalence of ‘high anxiety’ for SAB was 81% in our study which decreased to 66% in the video group before surgery.Conclusion:Multimedia information in the form of a short audiovisual clip is an effective and feasible method to reduce perioperative anxiety related to SAB.
Background and Aims:
There have been various methods tested for reducing preoperative anxiety in children, but very limited literature is available in the Indian scenario. Our aim was to analyse the effect of an informative video about the anaesthetic technique on preoperative anxiety in children.
Methods:
In all, 94 children were randomly allotted into two groups. Children in the study group were shown a peer modelling video depicting induction of general anaesthesia and recovery during the preanaesthetic check (PAC). Patients in the control group were given only verbal information during PAC. Anxiety was assessed on visual analog scale (VAS) for anxiety at two times. Baseline VAS score was recorded during PAC and preoperative VAS score was assessed prior to induction of anaesthesia. The VAS score was represented as median value. Data were analysed using the Mann–Whitney
U
-test for ordinal data and skewed quantitative data. Categorical data was analysed by using Chi-square test and t-test was applied for quantitative data. The significance threshold of
P
value was set at <0.05.
Results:
The median (interquartile range) preoperative VAS score was significantly lower in the study group [1 (0–1.3)] when compared with the control group [5 (3–5)] (
P
< 0.001). The mean preoperative pulse rate, mean preoperative systolic blood pressure and mean preoperative diastolic blood pressure were significantly lower in the study group when compared with the control group (
P
< 0.001).
Conclusion:
Multimedia information in the form of a peer modelling video helped reduce preoperative anxiety in children between 7 and 12 years of age.
Background and Aims:The complications of central venous catheterisation can be minimized by ensuring catheter tip placement just above the superior vena cava-right atrium junction. We aimed to compare two methods, using an electrocardiogram (ECG) or landmark as guides, for assessing correct depth of central venous catheter (CVC) placement.Methods:In a prospective randomised study of sixty patients of <12 years of age, thirty patients each were allotted randomly to two groups (ECG and landmark). After induction, central venous catheterisation was performed by either of the two techniques and position of CVC tip was compared in post-operative chest X-ray with respect to carina. Unpaired t-test was used for quantitative data and Chi-square test was used for qualitative data.Results:In ECG group, positions of CVC tip were above carina in 12, at carina in 9 and below carina in 9 patients. In landmark group, the positions of CVC tips were above carina in 10, at carina in 4 and below carina in 16 patients. Mean distance of CVC tip in ECG group was 0.34 ± 0.23 cm and 0.66 ± 0.35 cm in landmark group (P = 0.0001). Complications occurred in one patient in ECG group and in nine patients in landmark group (P = 0.0056).Conclusion:Overall, landmark-guided technique was comparable with ECG technique. ECG-guided technique was more precise for CVC tip placement closer to carina. The incidence of complications was more in the landmark group.
