BACKGROUND: The use of monitored anesthesia care (MAC) as the technique of choice for a variety of invasive or noninvasive procedures is increasing. The purpose of this study to compare the outcomes of two different methods, spinal anesthesia and ilioinguinal-hypogastric nerve block (IHNB) with target concentrated infusion of remifentanil for inguinal herniorrhaphy. METHODS: Fifty patients were assigned to spinal anesthesia (Group S) or IHNB with MAC group (Group M). In Group M, IHNB was performed and the effect site concentration of remifentanil, starting from 2 ng/ml, was titrated according to the respiratory rate or discomfort, either by increasing or decreasing the dose by 0.3 ng/ml. The groups were compared to assess hemodynamic values, oxygen saturation, bispectral index (BIS), observer assessment alertness/sedation scale (OAA/S), visual analogue scale (VAS) for pain score and patients' and surgeon's satisfaction. RESULTS: BIS and OAA/S were not significantly different between the two groups. Hemodynamic variables were stable in Group M. Thirteen patients in the same group showed decreased respiratory rate without desaturation, and recovered immediately by encouraging taking deep breaths without the use of assist ventilation. Although VAS in the ward was not significantly different between the two groups, interestingly, patients' and surgeon's satisfaction scores (P = 0.0004, P = 0.004) were higher in Group M. The number of the patients who suffered from urinary retention was higher in Group S (P = 0.0021). CONCLUSIONS: IHNB under MAC with remifentanil is a useful method for inguinal herniorrhaphy reflecting hemodynamic stability, fewer side effects and higher satisfaction. This approach can be applied for outpatient surgeries and patients who are unfit for spinal anesthesia or general anesthesia.

Objective: There is limited data on the outcomes of cardiac arrest occurring in emergency departments (ED). The objective of this study was to identify the factors associated with these outcomes, primarily the survival to hospital discharge and the neurological status at discharge in emergency department cardiac arrest (EDCA) patients. Methods: A retrospective study was conducted in a tertiary hospital. Adult patients aged over 18 years who had suffered an in-hospital cardiac arrest in the ED between July 2018 to June 2021 were included. The primary outcome was the survival to hospital discharge. Descriptive statistics and logistic regression analyses were performed. Results: We identified 157 ED arrests. Among these, 57.9% of the patients died in the emergency room. A total of 24.1% obtained survival discharge. The combined existing illnesses, such as renal insufficiency or malignancy were directly related to the survival of the patients. A cardiac and respiratory cause of arrest increased the probability of survival (P<0.001). The shorter the time spent on cardiopulmonary resuscitation (CPR), the higher the chances of survival (odds ratio of 0.84). The subjects in both the survivor and deceased groups were classified as Korean Triage and Acuity Scale 2 (KTAS 2: emergency) or higher (P=0.719). There was no difference in the ED occupancy, which is an emergency room overcrowding indicator. Conclusion EDCA patients are already in a clinically deteriorated condition. The underlying clinical conditions, the cause of cardiac arrest, the initial rhythm, and the CPR duration time are directly related to the patient’s chances of survival and prognoses. Therefore, it is possible to identify these factors at an early stage and take the appropriate management measures.

OBJECTIVE: A recent revision of the FIGO staging system does not recommend the mandatory use of cystoscopy and sigmoidoscopy. The objective of this study was to assess the clinical utility of CT or MRI scans for ruling out bladder or rectal invasion and determine the indication for endoscopy in patients with cervical cancer. METHODS: We retrospectively reviewed 769 patients with cervical cancer, who underwent imaging and endoscopic work-up between January 1997 and December 2010. Using endoscopy as the standard reference for comparison, we calculated the sensitivity, specificity, positive predictive value (PPV), negative predictive value (NPV), and accuracy of the imaging modality for bladder or rectal invasion. RESULTS: The CT scan showed 68.2% and 85.7% for sensitivity and 96.4% and 98.9% for specificity in detecting bladder and rectal invasion, respectively. CT scan provided a low PPV (51.7%, 54.5%) and a high NPV (98.2%, 99.8%). MRI scan showed 88.0% and 75.0% for sensitivity and 93.1% and 98.9% for specificity in detecting bladder and rectal invasion, respectively. MRI scan provided a low PPV (35.6%, 42.9%) and a high NPV (99.4%, 99.7%). The accuracies of CT and MRI scans in identifying bladder invasion were 94.9% and 92.8%, respectively. The accuracies of CT and MRI in identifying rectal invasion were 98.7% and 98.6%, respectively. CONCLUSION: The results of this study demonstrate that additional invasive endoscopy is not necessary for patients who present with no invasion on imaging work-up, and therefore, endoscopy should be considered a tool for confirming cases that are positive for invasion based on imaging work-up.
