Aims:The purpose of this study was to construct new reference range for fetal middle cerebral artery peak systolic velocity (MCA-PSV) in uncomplicated pregnancy at 19-40 weeks of gestation.
Methods:This was a prospective cross-sectional study involving 400 singleton pregnancies between 19 and 40 weeks of gestation without any known risk factors of adverse pregnancy outcome who were referred for routine obstetric examination. The protocol included the doppler examination of fetal middle cerebral artery (MCA) within 2 mm after its origin from the internal carotid artery and data were used to construct the normograms and percentile fitted curves of each doppler parameter for different gestational age.Results: Among 400 singleton uncomplicated pregnancies between 19 and 40 weeks of gestation maximum number of pregnancies (10%) was at 19 weeks of gestation and minimum (2.5%) was at 31 weeks. The fetal peak systolic blood flow in the MCA showed significant correlation with period of gestation. Mean MCA-PSV was 22.35 ± 3.05 at 19 weeks of gestation which increased to 67.73 ± 9.92 at 40 weeks. The MCA-PSV showed continuous increment with increasing gestational age Conclusions: Continuous increment in the peak systolic volume with advancing gestational age was obtained which was consistent with the previous studies done by various authors. The percentile fitted values and normograms will be valuable for the serial measurement of the peak systolic volume of the middle cerebral artery for complicated pregnancies.
Background: The most important goal of anaesthesia for geriatric patients with comorbid diseases is to maintain normal homoeostasis of different systems during and after surgery. This prospective study was conducted to evaluate the success rate and associated complications of the caudal epidural block for transurethral resection of prostate in elderly patients with comorbid diseases.Methods: This is a prospective study of a cohort of 100 elderly patients posted for transurethral resection of prostate with comorbid diseases belonging to American Society of anaesthesiologists physical status II, III and IV over a period of 1 year from April 2015 to April 2016. Standard recommended technique for caudal epidural block was followed. Time of onset, spread, duration of analgesia, intensity of block, complications, and unwanted effects were noted.Results: The mean age was 73.5+-7.69. Eighty-two percent patients belonged to ASA III and IV grade. The majority (87%) had excellent to a good quality of anaesthesia with no motor block. 83% of patients had the onset of analgesia between 5-15 minutes and 78% had a duration between 90-130 minutes. Three patients had patchy analgesia and they were considered as a failure. No death was encountered in the study.Conclusion: Caudal epidural block is a safe, effective anaesthetic technique for transurethral resection of the prostate in elderly with comorbid diseases of other systems.
