Abstract Background Patients undergoing gastroenteroscopy during sedation are prone to aspiration, and most patients with dyspepsia have delayed gastric emptying. This study aimed to investigate the feasibility of measuring the gastric antrum cross-sectional area (CSA) to supply a novel clinical diagnostic reference value in patients with dyspepsia. Methods Patients with dyspepsia undergoing elective gastroscopy were included. The Perlas qualitative 0–2 grading scale score was determined before the operation. The anteroposterior diameter (D1) and craniocaudal diameter (D2) between gastric antrum serosal surfaces were measured perpendicular to each other in the supine and right lateral decubitus (RLD) positions. CSA values in the supine position and RLD position were determined. Gastric contents were endoscopically suctioned with the volumes measured and noted as actual gastric volume. Multiple regression analysis was used to fit a mathematical model for estimating the gastric volume. Receiver operating characteristic (ROC) curves were constructed to determine the accuracy of RLD CSA to detect gastric volumes of > 0.8 ml/kg. Results A total of 117 patients were enrolled and divided into a functional dyspepsia (FD) group and an organic dyspepsia group according to gastroscopy findings. For a gastric volume of > 0.8 ml/kg, cut-off values for FD and organic dyspepsia were 6.7 cm2 and 10.0 cm2, respectively. Two new modified mathematical models were derived to predict an estimated gastric volume for FD and organic dyspepsia: volume = 3.93 × RLD CSA - 0.47 × age; and volume = 6.15 × RLD CSA - 0.61 × age. Conclusion We used the cut-off value of the antral area for the fast diagnosis of gastric volumes in patients with dyspepsia, which may assist clinicians in identifying patients at risk of aspiration.

Abstract Background Lumbar puncture in the lateral decubitus position will make the neonates uncomfortable and is likely to cause position change and unstable vital signs, and the application of sedative drugs will cause adverse effects. This study explored a novel method for lumbar puncture in the prone position for low weight neonates. Methods The neonates were randomly assigned into the standard position group receiving lumbar puncture in the lateral decubitus position; and the improved position group receiving lumbar puncture in the prone position. The success rate of first time attempts and the overall success rate of lumbar puncture, incidence of adverse effects, NIAPAS scores were collected and compared between these two groups. The difference in success rate and adverse effects incidence rate was analysed through Chi-square. Student’s t-test was used for the test of NIAPAS rating. Results The improved position group had a higher success rate of first attempt and overall success rate, significantly lower incidence of adverse effect and lower NIAPAS scores than those of the standard position group (P<0.05). Conclusion This lumbar puncture in the prone position is safer, more effective, and more comfortable for preterm neonates and those with low birth weight. Thus, this method is worth of further promotion. Trial registration Registration number, ChiCTR2100049923; Date of Registration, August 11, 2021; Retrospectively registered.

Aim: The main purpose of this present study is to determine the effects of sitting (S) and lateral (L) position during spinal anaesthesia on patient satisfaction, Post dural puncture headache (PDPH), Post-Operative Nausea and Vomiting (PONV). Study Design: Prospective comparative study Place and Duration of Study: Charusat Healthcare and Research foundation (CHRF), Changa, Gujarat, between September 2021 to November 2021. Methodology: A total of 50 female volunteers who were above the age of 18 years, had an American Society of Anaesthesiologist (ASA) status of I & II and those who have undergone hysterectomy surgery are included in this study. The patients were categorized into two groups, group S (n=25) and group L (n=25). Patients were asked about PONV 4 hours after surgery and the possibility of PDPH on post-operative days 1 and 2. The study was analysed by using descriptive statistics, chi-square and Kruskal-Wallis test. Results: When comparing the incidence of PDPH on post-operative day 1 and day 2, there is a statistically significant difference between the Sitting (group S) and Lateral decubitus (group L) groups (P-value= 0.14 and.001). On the other hand, there is no statistical significant difference found for PONV when compared between both the groups (P- value= .776). Conclusion: Spinal anaesthesia with lateral decubitus position has better outcomes than sitting position for the incidence of Post dural puncture headache. However, there is no difference in both groups for PONV.

ABSTRACTIntestinal gas results in low quality imaging in abdominal ultrasound in domestic animals. On dogs, suggested preparation protocols are varied and low studied. The aim of this work was comparing the efficacy between two preparations in improving the complete abdominal ultrasound exam and pancreas preview. 40 dogs were enrolled in this study. They were separated in two groups (NS diet: fasting; WS diet: fasting added to simethicone). The pancreas images were taken from left lateral decubitus. A score of one to three (1: bad, 2: fair and 3: good) measured separately the quality of the complete exam, left and right limbs and pancreatic body. In both treatments, there were results above 50% of good images of the complete exam and right limb of the pancreas. Otherwise, there were results above 90% of bad images of the right limb and pancreatic body. According to the fact of there is no statistically significant difference between the diets, as well submitted animals to the NS diet as the WS diet, all the results obtained from this work (bad or good images) could be acquired from any of both diets. The good abdominal exam preview as well submitted animals to the simethicone as those without the medication refute this medicine requirement to the abdominal ultrasound exam, but not to the evaluation of the left limb and pancreatic body.

Abstract Background Increasing numbers of tick-borne pathogens are being discovered, including those that infect humans. However, reports on co-infections caused by two or more tick-borne pathogens are scarce. Case presentation A 38-year-old male farmer was bitten by a hard tick, presented with fever (37.7 °C), severe headache and ejection vomiting. Lumbar puncture was performed in the lateral decubitus. The cerebrospinal fluid (CSF) was clear, and analysis showed severe increased pressure (320 mm H2O), mild leukocytosis (126.0 × 106/L, mononuclear cells accounting for 73%) and elevated total protein concentration (0.92 g/L). Bacterial cultures of CSF and blood were negative. The diagnosis of Rickettsia raoultii and Tacheng tick virus 1 (TcTV-1) co-infection was confirmed by amplifying four rickettsial genetic markers and the partial small (S) RNA segment of TcTV-1 from the patient’s blood. The patient gradually recovered after treatment with levofloxacin and ribavirin. Conclusions This is the first reported co-infection case with fever and meningitis caused by R. raoultii and TcTV-1. It is vital to screen for multiple pathogens in tick-bitten patients, especially in those with severe complex symptoms.
