As a result of the aging US population and the subsequent increase in the prevalence of coronary disease and atrial fibrillation, therapeutic use of anticoagulants has increased. Perioperative and periprocedural management of anticoagulated patients has become routine for anesthesiologists, who frequently mediate communication between the prescribing physician and the surgeon and assess the risks of both thromboembolic complications and hemorrhage. ⋯ In this review, we will discuss the most commonly used anticoagulants used in outpatient settings and discuss their management in the perioperative period. Special considerations for regional anesthesia and interventional pain procedures will also be reviewed.

Randomized Controlled Trial
The optimal combination of mechanical ventilator parameters under general anesthesia in obese patients undergoing laparoscopic surgery.
Pulmonary dysfunction after laparoscopic surgery is commonly seen in the high-risk group of obese patients. To reduce or avoid this complication caused by an improper combination of mechanical ventilation parameters, we conducted the following trial of 3 factors with 3 levels of mechanical ventilation, aimed to obtain the low airway pressure with good ventilator effects. ⋯ The best combination of respiratory parameters is A3B1C2, that is, f=9beats per minute, VT=8mL/kg, and I:E=1:2.0. That is, neither small tidal volume and faster frequency nor slow frequency large tidal volume is a good choice. To let obese patients under general anesthesia can obtain a lung protective effect of low airway pressure with good ventilation; it is noteworthy that (1) I:E of airway pressure (PIP, Pmean) is the important impact factor for the protection of the lung and (2) I:E of airway pressure (PIP, Pmean) is the factor with opposite properties.

Comparative Study
King Vision video laryngoscope versus Lightwand as an intubating device in adult patients with Mallampatti grade III and IV patients.
Anticipated and unanticipated difficult airways are often encountered by anesthesiologists in their clinical practice. There are various devices available in such situations. We aim to compare King Vision video laryngoscope and Lightwand for their performance as an intubating device in predicted difficult intubation. ⋯ Mean intubation time using King Vision video laryngoscope (19.50±6.73 seconds was lower than the intubation time using Lightwand 25.40±7.42 s, P=.00). The difference between number of attempts, success of intubation, numbers of adjustment maneuvers were comparable. There was a significant rise in heart rate within the groups from the pre-induction values. However inter group variations were similar. In addition, there was a significant rise in mean arterial pressure within the groups from the pre-induction values. Inter group variations show less increase in mean arterial pressure with Lightwand at immediate post intubation (P=.0234) and at 3 min and 5 min post intubation anesthesia.

Randomized Controlled Trial Comparative Study
Randomized comparison of the feasibility of three anesthetic techniques for day-case open inguinal hernia repair.
Comparison of local anesthetic infiltration (LAI), spinal anesthesia (SPIN) and total intravenous anesthesia (TIVA) for open inguinal herniorrhaphy. We hypothesized that patients receiving LAI could be discharged faster than SPIN and TIVA patients. ⋯ Logistically, LAI was superior because of the fastest recovery postoperatively. The anesthetic techniques were adequate for surgery in all but a few LAI and SPIN patients. Lack of urinary retention was probably related to the small IV infusion volumes.

Randomized Controlled Trial
Impact of time interval between remifentanil and propofol on propofol injection pain.
To determine the most effective time interval between remifentanil and propofol (TimeRP) for the prevention of propofol injection pain in association with remifentanil dosage. ⋯ The efficacy of remifentanil pretreatment for preventing propofol injection pain can be influenced by the time interval between remifentanil and propofol as well as the remifentanil dose.
