We designed this study to expand the usage of ultrasound to detect early occurrence of hypovolemia. We explore the potential use of inferior vena cava (IVC) and abdominal aorta (AA) diameter index (IVC:AA) measured ultrasonographically to detect class 1 hypovolemic shock with blood loss less than 15%.ᅟ
According to the class of hypovolaemic shock, a blood loss less than 750 ml is not associated with the physiological changes. As a result it may cause a delay in fluid resuscitation. We postulate inferior vena cava (IVC) diameter reduction in inspiration and expiration may resemble the significant volume of blood loss in a healthy adult. We conducted a study to examine the changes of the IVC diameter pre and post blood donation.The inferior vena cava diameter during inspiration (IVCi) and expiration (IVCe) were measured using ultrasound (GE HEALTH) in supine position before and after blood donation of 450 ml. Paired t-test and Wilcoxin rank test were used to analyse the data. Forty two blood donors enrolled during the study period. The mean age of blood donors was 32.3 +/- 8.9 and mainly male blood donors. The mean IVCe of pre and post blood donation was 18.5 +/- 6.2 mm (95%CI 18.23, 18.74) and 16.6 +/- 6.6 mm (95%CI 16.35, 16.76) respectively. Meanwhile, the mean IVCi of pre and post blood donation was 17.1 +/- 8.6 mm (95%CI 16.89,17.30) and 15.6 +/- 6.6 mm (95%CI 15.43,15.81) respectively. The mean difference of IVCe pre and post blood donation was 1.9 +/- 0.5 mm (95%CI 1.75, 2.13) (p<0.001). In contrast, the mean difference of IVCi pre and post blood donation was 1.5 +/- 0.5 mm (95%CI 1.34, 1.68) (p<0.001). As a conclusion, the measurement of IVC diameter by ultrasound can predict the volume of blood loss in simulated type 1 hypovolaemia patient.
Introduction: Operative laparoscopy is the gold standard approach for treatment of tubal pregnancy. Although benefits of this approach are well established, data on its uptake trend in Malaysia is largely unknown. Objective: This study aims to determine the operative laparoscopy uptake in management of tubal pregnancy at a busy tertiary hospital and whether the benefits associated with laparoscopic surgery was achieved. Materials and Methods: This prospective observational study was conducted on all women admitted for tubal pregnancy at Hospital Sultanah Aminah, Johor Bahru, a public tertiary hospital over a period of 12 months. The on-call team was responsible for the surgical approach. Patient’s clinical presentation, operative laparoscopic uptake, factors affecting the choice of approach and duration of hospitalization were analyzed. Results: The tubal pregnancy rate was 7.6 per 1000 deliveries. Twenty- seven of the 138 cases (20%) had hypovolemic shock, requiring urgent laparotomy and were excluded from study. The operative laparoscopy rate for stable tubal pregnancy was only 42.3% (47 of 111 cases). Women managed laparoscopically were associated with a significantly higher pre-operative hemoglobin level, mostly nullipara and had surgery performed during office hours. They waited longer for their surgery but were discharged earlier compared to the laparotomy group. There was no difference in the duration of hospitalization. Conclusions: Less than half of all hemodynamically stable tubal pregnancies in our hospital had operative laparoscopy. The current laparoscopy uptake rate can be further improved.
Barium enema investigation is regarded as a safe investigative procedure. Rarely, it may cause complications such as colonic perforation and barium intravasation. Barium intravasation may be caused by the inadvertent introduction of the catheter into the vagina, thereby into the vaginal venous plexus. It may also occur through mechanical colonic perforation with the catheter, or via diseased bowel conditions. This may lead to complications such as liver microabscesses, massive pulmonary embolism, hypovolemic shock, disseminated intravascular coagulopathy and even sudden death. With that in mind, we would like to report an interesting case of barium intravasation into the portal venous system via the vagina venous plexus. The patient experienced abdominal discomfort with mild per vaginal bleed and went into disseminated intravascular coagulopathy. She received supportive management and she made a full recovery.
