Hip fracture is one of the most common traumatic fractures in geriatric patients. With the increase in the geriatric population, physicians are more concerned about anesthetic management of these patients and a lot of articles have been published in relation to geriatric hip fracture. Due to age related comorbidities and physical status, perioperative management of these patients are complex and related to mortality and morbidity. Anesthesia and pain control for these patients are directly related to the postoperative outcome. This article summarizes the most recent opinions about perioperative management of geriatric hip fracture patients at the point of preoperative evaluation, anesthetic managements, and pain control.

The increase in mortality and morbidity associated with the use of muscle relaxants, is associated with a lack of clinical pharmacological knowledge of the drugs, and a lack of understanding the risk of postoperative residual curarization. This is due to the absence of standards for neuromuscular monitoring. Clinicians experienced in neuromuscular monitoring and using muscle relaxants in the clinic may have some queries regarding the monitoring: Why should neuromuscular monitoring be done? Are clinical tests really not effective? Why is it not good when I actually perform neuromuscular monitoring? Would using sugammadex not require neuromuscular monitoring? This review answers most of the questions that many clinicians have, and also forwards the knowledge required of clinicians. [ABSTRACT FROM AUTHOR]

Background: This study was designed to assess whether pre-anesthetic administration of dexmedetomidine reduces the postoperative consumption of opioids, in patients receiving patient-controlled fentanyl after gynecological laparotomy. Methods: This was a prospective, randomized, double-blind, controlled study. Ten minutes before induction of anesthesia, 36 patients scheduled for elective gynecological laparotomy were assigned to receive either normal saline (group N) or dexmedetomidine 1 μg/kg (group D). A patient-controlled analgesia (PCA) device was used to administer fentanyl for the postoperative 24 h period. Cumulative fentanyl consumption and pain score were assessed at postoperative 30 min, 6 h and 24 h. Patient's satisfaction for pain control and other side effects (nausea, sedation score) were recorded for all corresponding time points. Results: There was no significant difference between the groups in cumulative fentanyl consumption (Group N: 11.1 ± 3.2 μg/kg, Group D: 10.3 ± 2.9 μg/kg, P value: 0.706). The incidence of side-effects did not differ between the groups. Both groups showed similar blood pressure after anesthesia induction. However, 10 min after anesthesia induction, the heart rates in group D were significantly lower than group N (P = 0.0002). Conclusions: In patients undergoing gynecological laparotomy, the pre-anesthetic administration of single loading dose dexmedetomidine (1 μg/kg) given 10 min before anesthesia induction did not reduce the PCA consumption of postoperative fentanyl or the pain score.

Background: Perioperative hypothermia, defined as a core temperature under 36oC, increases the risk of cardiac complication, bleeding and infection. This study aimed to compare the hypothermia- preventing effects of a warming blanket (Ready-heat®) and one-layer cotton blanket in patients undergoing transurethral resection of the bladder (TURBT) under general anesthesia. Methods: Patients undergoing TURBT under general anesthesia were allocated to the warming blanket (N = 23) or one-layer cotton blanket (N = 23) groups. Ten minutes before induction of anesthesia, warming blanket or one-layer cotton blanket was applied according to the assigned group. Tympanic temperature was measured just before induction of anesthesia. Esophageal temperature and tympanic temperature were measured from 20 min after induction of anesthesia at 10-min intervals. Tympanic temperature was measured at 10-min intervals over a 30-min period in the post-anesthesia care unit (PACU). In addition, the incidence and intensity of shivering and thermal comfort were also measured. Results: The core temperature during general anesthesia showed no significant intergroup difference. The warming blanket group showed a lower incidence of hypothermia at 1 h after induction of anesthesia. Tympanic temperature, the incidence and intensity of shivering, and thermal comfort in the PACU showed no significant intergroup differences. Conclusions: Application of the warming blanket or one-layer cotton blanket for 10 min before induction of anesthesia showed no hypothermia-preventing effects. However, at one hour after induction of anesthesia, warming blanket application reduced the incidence of hypothermia to a greater degree than one-layer cotton blanket. [ABSTRACT FROM AUTHOR]

In this paper, it can be applied to a walkie-talkie, the RFID / USN 920 MHz band(917～923.5 MHz) and WiFi 2.4GHz band(2.4～2.483 5GHz) return loss is 10 dB over the band, on-board dual band with omni-directional radiation characteristics is proposed. The basic structure designed antenna is used meander monopole antenna. It was used as double stubs and tabs for antenna designs that meet the criteria proposed. The double stub and the tab affects the reactance of the antenna to form a common-mode and differential-mode in the stub to improve the antenna characteristics and return loss in the bandwidth, gain and radiation characteristics. The system size of walkie-talkie is 52×77 mm2, the size of the antenna is limited to 52×15 mm2, the thickness of FR4 dielectric substrate is 0.8 mm, FR4 dielectric constant 4.4 is used. For experimental results, the return loss is measured more than 10 dB, the maximum gain is measured 1.95 dB, the maximum bandwidth is measured 360 MHz, the radiation characteristic is measured omni-directional. By a walkietalkie terminal design applying the results of the paper, the handset"s price competitiveness and production efficiency can be improved. [ABSTRACT FROM AUTHOR]
