ABSTRACT
Objective: To determine frequency of color blindness and to assess self awareness regarding this ailment amongst the youngest age group in southern Punjab province of Pakistan
Study Design: Cross sectional study
Place and Duration of Study: Combined Military Hospital [CMH] Bahawalpur, from Jan 2016 to Jun 2017
Patients and Methods: Non probability consecutive sampling was done. Candidates who appeared for medical fitness examination were included; all of them belonged to the southern Punjab province of Pakistan. Visual acuity and best corrected visual acuity was assessed. Color vision was checked by using Ishihara color vision charts. Anterior and posterior segment examination of eyes was carried out
Results: Total 1000 candidates underwent color vision assessment. Overall 3.1 percent [31/1000] of the candidates were found to be color vision deficient. Out of them, 93.54 percent [29] were unaware of their condition
Conclusion: The screened population showed color blindness to be present in 3.1 percent of the candidates. Most of the individuals were unaware of the condition
ABSTRACT
Intraoperative cardiac arrest in usual position [prone or lateral] present a unique challenge to the anesthesiologist, where changing to supine position can result in undue delay in initiating CPR or it is not feasible due to skull being fixed and opened by the surgeon. A 25 kg girl, 6 years old, was undergoing posterior cranial fossa surgery for fourth ventricle tumor excision. She went into hemorrhagic hypovolemic cardiac arrest, despite fluid resuscitation. Immediately, CPR was started in prone position with one hand at the midthoracic spine between the scapulae. The patient had ROSC after 20 min of CPR. Our patient did not have a favorable outcome, but the resuscitation in the prone position generated sufficient cardiac output while the correction of hypovolemia and hemostasis could be achieved. We recommend that immediate initiation of CPR even in prone position is the best choice in intraoperative patients, where change in position would result in delay in chest compression or make the surgical access impossible
