Evaluation of recovery of oxygen saturation and rate of perceived exertion in different body positions after submaximal exercise test in normal healthy individual

Background: Oxygen saturation is the fraction of oxygen saturated hemoglobin relative to total hemoglobin in blood. Normal oxygen saturation level in humans are 95-100 percent. Breathlessness is an unpleasant sensation of rapid or difficult breathing. The reason behind the subject experiencing breathlessness is that the body demands more oxygen than it supplies. Thus this study is conducted to Evaluate Recovery of Oxygen saturation and Rate of perceived exertion in different body positions after submaximal exercise testing in normal healthy individuals. Methodology: It was Pre and Post Study Design with 6 months duration including 40 healthy students recruited by purposive sampling method. The outcome measure was Recovery of Oxygen saturation and rate of perceived exertion. Result – Using the Paired t test, this shows that fastest recovery of oxygen saturation occurs in prone position that is within 1 min (99±0.96) than supine within 3 min (99±0) than upright sitting within 3 min (99±0) and fastest recovery of rate of perceived exertion occurs in prone position that is within 1 min (0.825±0.99) than supine within 3 min (0±0) than upright sitting within 3 min (0±0). Conclusion - From the present study we evaluate the Recovery of oxygen saturation and RPE in supine, prone, upright sitting position and we found that the fastest recovery of oxygen saturation and Rate of perceived exertion occurs in prone position than supine and upright sitting position after submaximal exercise testing in normal healthy individual.

Comparison of the Hypotension in Lateral Verses Sitting Positions during Induction of Spinal Anaesthesia for Caesarean Section

Objective: To compare the hypotension in lateral verses sitting positions during induction of spinal anaesthesia for caesarean section. Study Design: This is a Randomized control trial (RCT) study. Setting: Study carried out at Department of Anaesthesiology, Surgical Intensive Care Unit and Pain Management, Civil Hospital, Dow University of health sciences Karachi, from December 2018 to June 2019. Materials and Methods: All women age 18 to 45 underwent elective caesarian section having ASA I and II, singleton pregnancy on ultrasound with parity ≤3 were enrolled. Patients were randomized to receive spinal anaesthesia in the lateral position (Group L) or the sitting position (Group S) through lottery methods. Using the L3-4 interspace, patients received intrathecal plain bupivacaine, 10mg or 12 mg according to their height, after which they was placed immediately in the supine position with left uterine displacement. Maternal blood pressure was measured with the help of Non-invasive BP apparatus. BP was recorded at baseline then every 5 min till 30 minutes by anesthetist who was unaware of parturient group. Any single or more reading of SBP of <90 mmHg was considered as Hypotension. Results: Mean age of the patients in lateral group was 31.49 ±10.87 years and mean age of the patients in sitting group was 31.80 ±10.77 years (p-value 0.869). Majority of the patients 35 (62.5%) with hypotension were presented with sitting position. Chi square test was applied and statistically significant difference was observed between groups (p-value 0.012). Conclusion: We concluded that less frequency of hypotension was observed when spinal anaesthesia for caesarean section using plain bupivacaine in the lateral position.

Postural Variabilities Associated with the Most Comfortable Sitting Postures: A Preliminary Study

This study examined postural variabilities based on the self-perceived most comfortable postures of 12 participants (six men and six women) when sitting on three commonly used types of chairs (a stool, computer chair, and gaming chair). Participants’ global joint angles were recorded and analyzed. Of the chairs studied, the stool was not adjustable, but the computer and gaming chairs were moderately and highly adjustable, respectively. During the test, participants were encouraged to adjust the chairs until they perceived that the most comfortable posture had been reached. The results demonstrated that in a sitting position perceived to be comfortable, the participants’ postural variabilities with respect to global joint angle, calculated from five repetitions, were unexpectedly high for all three chair types, at approximately 9.4, 10.2, and 11.1° for head inclination, trunk angle, and knee angle, respectively. The average differences in range for each joint angle among the three chair types were relatively low, with all values within 3°. The result also showed that gender (p < 0.01) and chair type (p < 0.001) significantly affected trunk angle, whereas these variables did not affect head inclination or knee angle (p > 0.05). The preliminary results observed unexpectedly high variabilities in sitting posture when the participants sat at a posture that they perceived to be the most comfortable. The findings also indicated an inherent difference in comfortable sitting posture between genders; women tend to extend their trunk backward more than men. For permanent use with only an initial adjustment and memory-aided seat design, designers should minimize the loads that are borne by body parts over a prolonged period due to an unchanging sitting posture.

To compare the impact of sitting and supine position on behavioral distress during immunization among children (1-3 years) in selected immunization clinics

Background of the study: Immunizations cause distress in children due to its acute pain. Younger children are particularly in need of intervention because they report more pain and display more behavioral distress during painful procedures. One of the effective non-pharmacological interventions of acute management is comfort position given by the parent. Comfort position provided by the parent during immunizations has been demonstrated to be useful in infants, toddlers and pre-school children. Yet, this simple intervention is not used on a routine basis. Aim: The aim of the study was to compare the impact of sitting and supine position on behavioral distress during immunization among children (1-3 years) in selected immunization clinics. Objectives of the study: To determine the impact of sitting position on behavioral distress of children receiving immunization (Group I - experimental group). 1. To determine the impact of supine position on behavioral distress of children receiving immunization (Group II - control group). 2. To compare the impact of sitting and supine position on behavioral distress of children during immunization. Methods: The research design adopted for the study was post test only control group design. Immunization clinic selected based on the convenience of the investigator. Purposive sampling technique used to select the sample and the sample were assigned randomly in to Group I(experimental group) and Group II(control group).To assess the impact of position: PBRS-R was used to assess the behavioral distress of children during immunization injection. Results: The collected data was analyzed by descriptive and inferential statistics. 1. Assessment of behavioral distress scores during immunization injection showed significant difference in mean scores in Group I (16.4±2.30) and in Group II (28.45±2.59). 2. Comparison of behavioral distress scores in Group I and Group II showed that there is a significant difference (p<0.05) in behavioral distress between experimental (Group I) and control (Group II) group. 3. Item wise comparison of behavioral distress scores in Group I and Group II showed that there is no significant difference(p<0.05) in behavioral distress between experimental (Group I) and control (Group II) group. Interpretation and conclusion: Findings of the study revealed that the comfort position, i.e., sitting position was effective in reducing behavioral distress during immunisation. Hence, paediatric nurses ought to promote the use of comfort position to reduce behavioral distress associated with painful procedure.

Preclinical evaluation of noncontact vital signs monitoring using real-time IR-UWB radar and factors affecting its accuracy

Recently, noncontact vital sign monitors have attracted attention because of issues related to the transmission of contagious diseases. We developed a real-time vital sign monitor using impulse-radio ultrawideband (IR-UWB) radar with embedded processors and software; we then evaluated its accuracy in measuring heart rate (HR) and respiratory rate (RR) and investigated the factors affecting the accuracy of the radar-based measurements. In 50 patients visiting a cardiology clinic, HR and RR were measured using IR-UWB radar simultaneously with electrocardiography and capnometry. All patients underwent HR and RR measurements in 2 postures—supine and sitting—for 2 min each. There was a high agreement between the RR measured using radar and capnometry (concordance correlation coefficient [CCC] 0.925 [0.919–0.926]; upper and lower limits of agreement [LOA], − 2.21 and 3.90 breaths/min). The HR measured using radar was also in close agreement with the value measured using electrocardiography (CCC 0.749 [0.738–0.760]; upper and lower LOA, − 12.78 and 15.04 beats/min). Linear mixed effect models showed that the sitting position and an HR < 70 bpm were associated with an increase in the absolute biases of the HR, whereas the sitting position and an RR < 18 breaths/min were associated with an increase in the absolute biases of the RR. The IR-UWB radar sensor with embedded processors and software can measure the RR and HR in real time with high precision. The sitting position and a low RR or HR were associated with the accuracy of RR and HR measurement, respectively, using IR-UWB radar.

CS-5 A case of anaplastic pleomorphic xanthoastrocytoma in the pineal region

Tumors in the pineal gland are rare tumors that account for about 0.3% of all brain tumors and have various histological types of tumors develop with germinoma, pineocytoma, and pineoblastoma in that order. On the other hand, pleomorphic xanthoastrocytoma (PXA) is a rare tumor of less than 0.2% and frequently occurs in supratentorial cerebral surface of children and young adults.A case was a 61-year-old man whose pineal tumor was found due to visual disturbance. MRI showed a 23 mm-sized lesion with cysts and inhomogeneous enhancement in the pineal gland. Partial calcification was observed, but there was no non-communicating hydrocephalus, and no increase in HCG-β and AFP with blood sampling. A midline suboccipital craniotomy was performed in the sitting position, a head-up surgery was performed using a 4K / 3D video microscope system (ORBEYE exoscope, Olympus) by the infratentorial supracerebellar approach (ITSCA). The bridging veins and precentral cerebellar vein were dissected to expose the posterior surface of the tumor, and internal decompression was performed. For the complication of air embolism, artificial cerebrospinal fluid was sprayed, and the bilateral internal jugular veins were compressed to confirm the inflow point. There was strong adhesion to the Rt vein of Rosenthal, and the site was removed intracapsularly. Finally, subtotal resection was performed with remaining the upper part of the tumor, a blind lesion behind the Vein of Galen. Vertical gaze palsy occurred after this operation, but it gradually improved over time. Tumor showed pathologically remarkable polymorphism, poor microvascular proliferation and necrosis, but mitotic figures 4–5 / 10HPF, MIB-1 index 10%, GFAP positive, no BRAF V600E mutation. There are few reports of PXA occurring in the pineal gland, and this case is the sixth case. It is also the first report for pineal tumors using ORBEYE through ITSCA in the sitting position.
