Because the cricoid force in children has not been quantified, clinicians wrongly used the 'adult' force. it has been found that the use of the adult force can result in compression and distortion of the child's airway and can lead to airway obstruction and difficult intubation. Based on known measurements of the cricoid surface area in children, the theoretical forces necessary to occlude the esophageal entrance have been calculated . These forces were found to be much less than the recommended adult force and much less than the forces that distort the airway as reported previously. Based on these theoretical calculations, the current study was performed to determine the effective cricoid force for pediatric groups (group 1 and group 2).

Adductor canal block (ACB) is a new technique gaining acceptance as an alternative analgesic method of femoral nerve block (FNB) following knee surgery. The advantage of ACB is its dominant sensory nerve block effect. It preserves quadriceps muscle strength compared with the FNB. This will serve as potential gain for early rehabilitation and thereby functional outcome. Adequate direct injection of local anesthetic into the canal will block four nerves: the saphenous nerve, the nerve to the vastus medialis, the medial femoral cutaneous nerve, and the terminal end of the posterior division of the obturator nerve. Anterior cruciate ligament reconstruction (ACLR) is often associated with postoperative severe pain. Postoperative early rehabilitation is the primary focus to restore pre-injury status and is an essential part of the full recovery, especially that this rehabilitation extents over a 6 month period. Early elimination of pain is necessary to achieve this goal. However, there are no clear conclusive clinical reports defining the adequate analgesic volume-dosage of local anesthetic for ACB for postoperative ACL pain management. The investigators speculated that volume-dosage manipulation play key role in the effective of ACB for postoperative pain. The investigators conducted this prospective, randomized, observer-blinded trial to compare 3 combinations of volume and dosage of 0.25 % bupivacaine for US-guided ACB. The first aim of the investigation is to compare the analgesic effect of ACB 0.25% bupivacaine of the 3 doses as assessed by the visual analog scale (VAS) pain scores. The second aim were duration of analgesia, as defined by first demand for analgesia, and subsequent 24-h consumption. Physiotherapy tolerance and time to discharge were evaluated. Side effects were also assessed.

the investigators have observed that women may require less CF than men to occlude the esophageal entrance, and that the routine use of 30 N in women may actually increase the incidence of airway-related problems. The objective of the current investigation was to test this hypothesis. In this study, real-time visual and dynamic means were used to assess the effectiveness of different forces applied to the cricoid cartilage in occluding the esophageal entrance in men and women. The patency of the esophageal entrance was directly visualized using the Glidescope Video Laryngoscope in anesthetized and paralyzed patients with and without CP. Evidence of closure of the esophageal lumen was confirmed by the inability to introduce a gastric tube (GT) into the esophagus under direct vision. New method , using Cricometer , was used to measure the applied force .
