A previous study has shown barium is instilled in the left lateral position or the prone position. However, we previously reported that the colonoscope can be readily inserted into the descending colon in the left semiprone position. Indeed, when the colonoscope was inserted in the left semiprone position, the lumen of the sigmoid colon was observed linearly and the colon position lowered toward the oral side. In addition, it was often observed that the rectosigmoid colon nearly overlapped with the sigmoid-descending colon junction when the patient was placed in the left semiprone position in the single-contrast enema examination. Therefore, we considered that the rectosigmoid colon is located in the highest position while the sigmoid-descending colon junction is located in the lowest position and various kinds of drugs can be readily administered into the proximal colon in the left semiprone position. Our new barium instillation method was devised and this method was performed to determine whether barium can be readily instilled into the proximal colon. Barium (300 ml) passed the hepatic flexure before air insufflation in 32 (67%) of the 48 patients by using our new barium instillation method. By contrast, barium (300 ml) passed the hepatic flexure before air insufflation in 3 (6%) of the 48 patients by using our conventional barium instillation method. These results suggest that effective rectal administration is possible by using our new barium instillation method compared with our conventional barium instillation method.

Abstract Background and study aims The adenoma detection rate (ADR) is an important quality metric of colonoscopy. Higher ADR correlates with lower incidence of interval colorectal cancer. ADR is variable between endoscopists and depends upon the withdrawal technique amongst other factors. Dynamic position change (lateral rotation of patients with a view to keep the portion of the colon being inspected at a higher level) helps with luminal distension during the withdrawal phase. However, impact of this on ADR is not known in a pooled sample. We performed a systematic review and meta-analysis to study the impact of dynamic position changes during withdrawal phase of colonoscopy on ADR Methods A comprehensive search of MEDLINE, EMBASE, Google Scholar, and the Cochrane Database was conducted from each database’s inception to search for studies comparing dynamic position changes during colonoscope withdrawal with static left lateral position (control). The primary outcome of interest was ADR. Other studied outcomes were polyp detection rate (PDR) and withdrawal time. Outcomes were reported as pooled odds ratio (OR) with 95 % confidence intervals (CI) with statistical significance (P < 0.05). RevMan 5.3 software was used for statistical analysis. Results Six studies were included in our analysis with 2860 patients. Of these, dynamic position change was implemented in 1177 patients while 1183 patients served as the controls. ADR was significantly higher in the dynamic position change group with pooled OR 1.36 (95 % CI, 1.15–1.61; P < 0.01). There was low heterogeneity in inclusion studies (I2 = 0 %). PDR was numerically higher in position change group (53.4 % vs 49.6 %) but not statistically significant (P = 0.16). Mean withdrawal time did not significantly change with dynamic position change (12.43 min vs 11.46 min, P = 0.27). Conclusion Position change during the withdrawal phase of colonoscopy can increase the ADR compared to static left lateral position. This is an easy and practical technique that can be implemented to improve ADR.

The gastric distribution of barium sulphate and its subsequent intestinal passage were examined by radiography in Potorous tridactylus. Barium sulphate administered in association with solid food passed to the sacciform forestomach from the tubiform forestomach. However, ingested barium sulphate suspension mainly entered the hindstomach via the gastric sulcus. Barium sulphate which entered the sacciform forestomach remained for no more than 1 h before passing to the hindstomach via the tubiform forestomach. The passage of contrast medium through the intestine was followed in adults administered barium sulphate suspension only. Contrast medium which entered the hindstomach was not detectable there after 10 min. Barium sulphate first arrived at the caecum and proximal colon after 20 min, and by 45 min the majority had reached these organs. It persisted in the caecum and proximal colon for several hours, during which there was some movement into the descending colon and rectum. These results lead towards a new interpretation of the role of the potoroine foregut and hindgut.

Previous measurements in isolated lung showed that alveolar liquid pressure was near the pleural pressure at a lung volume near functional residual capacity (FRC). In this study we verified that alveolar liquid pressure in vivo was similar to that of the isolated lung. In anesthetized paralyzed rabbits (3#x2013;4 kg, n = 9) ventilated with 100% O2 in the left lateral position, we made a pleural window between the fifth and sixth ribs near midchest by removing tissue down to the parietal pleura. Window height was 6 cm above the base of the lung. During apnea, alveolar liquid and pleural pressures were measured by puncturing through the pleural window with micropipettes connected to a servo-nulling pressure-measuring system. Pressures were measured at airway pressures of 0 (FRC) and 10 cmH2O both in vivo and postmortem. In vivo, alveolar liquid and pleural pressures relative to ambient pressure averaged -2.3 +/- 1.4 (SD) and -1.8 +/- 0.9 cmH2O at FRC and increased to 3.3 +/- 1.8 and 1.8 +/- 1.6 cmH2O after inflation to an airway pressure of 10 cmH2O, respectively. Similar values were obtained postmortem. These results were similar to previous measurements in the isolated lung.

Patient with critical condition had high morbidity and mortality rate. This condition is worsened by long term immobilization. Instability vital sign made nurses stationed delayed mobilization activities in ICU. Progressive mobilization must be started for ICU patient to decrease respiratory function, level of awareness and cardiovascular function. The objective of this study was to identify progressive mobilization activities on blood pressure parameters among critical patients in ICU. The design of this study was quai experiment design. Thirty respondents were included to the study using concequtive sampling. Progressive mobilization was given with head of bed 300 (HOB 300), head of bed450 (HOB 450) with  passive range of motion, continued with right and left lateral position. Anova repeated measurement was used to identify mean difference each of blood pressure. The result of this study show there is two moment sistolic change between HOB 300 to HOB 450 and HOB 450 to right lateral position (3,3%). There is nine moment diastolic change between HOB 450 to right lateral position (16,7%).   Keywords: blood pressure, ICU, Progressive mobilization

BACKGROUND: In the past ten years, liver biopsies have been used as a method to accurately diagnose the stage of fibrosis. OBJECTIVE: This study aimed to evaluate whether body position and exercise affect the measurement of liver Young’s modulus of healthy volunteers by real-time shear wave elastography (RT-SWE). Methods: RT-SWE was used to measure liver Young’s modulus in the supine and left lateral positions of 70 healthy volunteers at rest and measure the liver Young’s modulus in the lying position before exercise, and at zero, five, and ten minutes of rest after exercise. RESULTS: The liver Young’s modulus in the left lateral position was significantly higher than in the supine position (P< 0.05), and the measured value in the supine position was more stable than the left lateral position. The liver Young’s modulus measured at zero minutes after exercise was significantly higher than that measured before exercise (P< 0.05). The liver Young’s modulus measured at five minutes after exercise was significantly higher than that measured at zero minutes after exercise (P<0.05) and was not statistically different from the measured value before exercise (P> 0.05). The liver Young’s modulus measured at ten minutes after exercise was significantly higher from that measured at zero minutes after exercise (P< 0.05) and was not statistically different from the measured value at five minutes after exercise (P> 0.05). CONCLUSION: Body position and exercise have a significant impact on the measurement of liver Young’s modulus. It is recommended that the examinees take a supine position during the measurement, and measurement should be conducted at least ten minutes after exercise.

When an excised lung lobe undergoes atelectasis, its shape differs from that observed when lobar atelectasis occurs in an intact animal: the chest wall deforms the collapsing lobe. In eight anesthetized dogs in the left lateral position we measured lung volume and transpulmonary pressure during the development of atelectasis. We then induced atelectasis of the left lower lobe with the rest of the lung maintained at FRC and measured lobar volume and "translobar" (lobar minus esophageal) pressure. Lung and lobar volumes were measured by prebreathing the animal with 88% O2-12% N2, occluding the airway and observing the increase in lung or lobar N2 concentration. When the left lower lobe alone collapsed, translobar pressures were more negative than transpulmonary pressure at the same relative volume when the whole lung collapsed. This pressure difference, which represents the deforming force applied to the lobe minus the pressure costs of deformation, averaged 3 cmH2O at 50% FRC. Infusion of 25 ml of normal saline into the pleural space sharply reduced the difference pulmonary pressure during lung collapse: this difference was abolished at 80% FRC and halved at 50% FRC. The large effect of the small volume of fluid suggested that deforming forces were largely generated in relatively local areas, such as regions of the chest wall with sharp angulation.
