Mohamed, S. A. R., N. N. Mohamed, and D. Rashwan, "Pulse co-oximetry perfusion index as a tool for acute postoperative pain assessment and its correlation to visual analogue pain score", Research and Opinion in Anesthesia & Intensive Care, vol. s, pp. 62–67, 2015. Abstract2-vas.pdf

Background
A painful stimulus can produce vasoconstriction and a decrease in perfusion index (PI). The
visual analogue scale (VAS) is the most common pain assessment scale. However, it is affected
by psychometric instability. This study was designed to evaluate the correlation between VAS
as a subjective indicator of pain and PI as an objective indicator of pain.
Patients and methods
At postanesthesia care unit, a Masimo pulse co-oximetry perfusion index was attached to 70
adult patients of ASA I who underwent lumbar spine discectomy. At the time of the first request
for analgesia (T1) VAS was recorded together with the PI, heart rate (HR), mean arterial
blood pressure (MAP), peripheral oxygen saturation, and axillary temperature, following which
analgesia was given. Thirty minutes thereafter (T2) second measurements for the mentioned
parameters were taken.
Results
The PI was significantly higher at T2 than at T1 (mean increase% = 94.3 ± 82.7%). This
increase was associated with a statistically significant decrease in VAS, HR, and MAP. The
mean decrease% was 70.5 ± 19.88%, 11.1 ± 7.2%, and 3.96 ± 5.01% in VAS, HR, and MAP,
respectively. This means that the PI increases with adequate relief from pain, as indicated
by a decrease in VAS, HR, and MAP. A decrease in VAS was associated with an increase
in PI, but the correlation was not statistically significant as the degree of the increase in PI in
relation to the decrease in VAS was variable among patients.
Conclusion
PI can be added to other indicators of pain assessment in the postanesthesia care unit.

SA, Y., E. AH, and E. I., "Pulsatile Systems for Colon Targeting of Budesonide: in Vitro and in Vivo Evaluation", Drug Delivery, 2011. Abstract

The purpose of this study is to increase the lag time and prevent release of budesonide, a corticosteroid drug used in Crohn's disease for the first 5?h and efficiently deliver it to the colon. Eudragit S100 spray-coated capsules and pulsatile systems using tablet plugs of cellulose acetate butyrate (CAB), HPMC K4M, guar gum, and pectin were prepared. Eudragit S100-coated capsules released 80.62% after 5 h. In pulsatile systems, decreasing the ratio of the polymer significantly increased the rate and extent of drug release. Spray-coating with EUD S100 decreased the extent of drug release to 48.41%, 69.94%, 80.58%, and 45.23% in CAB, HPMC K4M, pectin, and guar gum, respectively; however, the entire amount was released in the target area. In the presence of bacterial enzymes, selected formulas showed nearly 100% release. X-ray imaging performed to monitor the capsules throughout the GIT in human volunteers of the capsules and spray-coated pulsatile systems with 25% guar gum in the plug showed bursting in the transverse and ascending colon, respectively. Both formulations showed marked reduction in induced rabbit colitis model.

A magnetic resonance imaging (MRI) study.", Clinical research in cardiology : official journal of the German Cardiac Society, vol. 95, issue 12, pp. 643-9, 2006 Dec. Abstract

AIMS: QRS prolongation is a negative prognostic factor for the development of ventricular arrhythmia after repair of tetralogy of Fallot (TOF). In this MRI study, we performed a multivariate analysis to determine the influence of volumetric and functional parameters as well as time factors on QRS duration.

METHODS AND RESULTS: Sixty-seven patients after surgical repair of TOF were studied using a 1.5T MRI. Measurement of the ventricles was performed with a multislice-multiphase sequence. Left and right ventricular volumes, ejection fractions (EF) and myocardial masses were determined. Pulmonary regurgitant fraction (PRF) was quantified by velocity encoded flow measurement in the main pulmonary artery. Maximum QRS duration was taken from a 12-channel ECG. Mean maximum QRS duration was 132 ms (+/- 29 ms). Mean PRF was 29.2% (+/- 13.4%). QRS duration correlated significantly with PRF (r = 0.49; p < 0.01; n = 54) and with right ventricular enddiastolic volume index (RVEDVI) (r = 0.29; p < 0.05; n = 67). Multivariate analysis revealed that the combination of PRF, postoperative period, age at surgical repair, and left ventricular (LV) enddiastolic volume are correlated with QRS prolongation.

CONCLUSION: In patients after repair of TOF, pulmonary regurgitation is related to QRS prolongation. Furthermore, even LV size plays a role in the enlargement of the QRS complex.
