results in the i-gel group, the success rate was 66.7% for placement on the first attempt, 16.7% for the second, and 3.33% for the third attempt. in the lma group, the success rates were 80.6% and 12.9% for the first and second attempts, respectively. failure in placement occurred in four cases in the i-gel and two cases in lma groups. the mean insertion time was not significantly different bet...

results sore throat was recorded in 32.9% of patients with lma and 44.2% of intubated patients, but it was not statistically significant (fisher’s exact test = 0.158). hoarseness was recorded in 3.5% of patients with lma and 24.4% of intubated patients (fisher’s exact test = 0.000). in 1.2% of patients with lma cough was recorded; it was also seen in 7% of the intubated patients (fisher’s exact...

Background & objectiveː Anesthetic management of pediatric cataract surgery is special as most these surgeries have to be completed under general anesthesia, and airway adequate ventilation take precedence care. We compared spontaneous vs. controlled ventilation, using laryngeal mask (LMA) with or without muscle relaxation showing their impact on different parameters in surgery.
 Metho...

Figure 1 shows an example of a light field camera with a pinhole mask in front of the sensor. If we look at the sensor in 1D and assume an total x-resolution of 900 pixels and a Θ resolution of 9, the local x resolution is 100. The disadvantages are therefore a loss in resolution and a loss of light, as most of the light gets blocked by the mask. Therefore, while this model is very clean on a t...

Background: masks and randomized control trial aims to pattern among critically Method: patients were selected by convenience sampling and were randomized to control and experimental group using parallel group design. The perception of patient’s sleep plugs and eye mask was evaluated Using Verran and Snyder that include three main sleep sub scales: disturbance, effectiveness, and supplementatio...

STUDY OBJECTIVE Although preoxygenation for emergency airway management is usually performed with nonrebreather face masks or bag-valve-mask devices, some clinicians also deliver supplemental high-flow oxygen by nasal cannula. We aim to measure the efficacy of supplemental nasal cannula oxygen delivery to conventional bag-valve-mask and nonrebreather face mask preoxygenation both with and witho...

In amblyopia, abnormal visual experience leads to an extreme form of eye dominance, in which vision through the nondominant eye is degraded. A key aspect of this disorder is perceptual suppression: the image seen by the stronger eye often dominates during binocular viewing, blocking the image of the weaker eye from reaching awareness. Interocular suppression is the focus of ongoing work aimed a...

In this paper, a fragile watermarking based on two-dimensional Separable Discrete Hartley Transform has been proposed for color image authentication (FWSDHTCIA). Two dimensional SDHT is applied on each 2 × 2 sub-image block of the carrier image in row major order and produces four frequency components in transform domain. Due to the high sensitivity of human eye on green channel, only one authe...
