[Surgical anesthesia using ultrasound-guided penile nerve block for adult hemophilia patient]. / Eriskin hemofili hastasinda ultrason rehberliginde penil blok ile cerrahi anestezi.

Ultrasound-Guided Dorsal Penile Nerve (DPNB) Block was performed to provide surgical anesthesia for a 22 years old ASA II patient who had hemophilia A and was undergoing circumcision surgery. 20 ml of 0.25% bupivacaine was used for the DPNB. Surgery was completed under block without complication. Twenty-four hours of the analgesia was provided following surgery.

[Superficial cervical plexus block in ear surgery: A case report]. / Kulak cerrahisinde yüzeyel servikal pleksus blogu: Olgu sunumu.

The aim of this study was to share our experience with the application of a superficial cervical plexus block in the ear operation of a 59-year-old male patient. The superficial cervical plexus provides sensory innervation of the superficial structures of the anterolateral neck, ear, and shoulder. Ultrasound-guided cervical plexus block may be an alternative method for both anesthesia and analgesia in ear surgery.

Which nostril should be used for nasotracheal intubation with Airtraq NT®: the right or left? A randomized clinical trial

Background/aim: Nasotracheal Airtraq is specifically designed to improve the glottis view and ease the nasotracheal intubation process in normal and difficult cases. Materials and methods: After Ethics committee approval, we decided to enroll 40 patients with an ASA physical status of I or II, between 18 and 70 years of age undergoing elective maxillofascial, oral, and double chin surgery to determine which nostril is more suitable for nasotracheal intubation with nasotracheal Airtraq. Patients were randomized into the right and left nostril groups. Results: Demographic and airway characteristics were similar among the groups. Nasotracheal intubation through the right nostril was shorter than that of the left nostril during nasotracheal intubation with the Airtraq NT (P < 0.001). 90° counterclockwise rotation of the tip of the tube was needed for directing the tube into the vocal cords in both right and left nostril groups (72% vs 88%). External laryngeal pressure and head flexion maneuvers can ease the intubation from the left nostril (P < 0.001 vs P = 0.03). Cuff inflation maneuver also can be helpful in some cases. We did not need any operator change or Magill forceps for any of the patients. Conclusion: Nasotracheal intubation via the right nostril can be safely and quickly performed with the Airtraq NT without the need of Magill forceps. We recommend the use of the 90° counterclockwise rotation, external laryngeal pressure, and head flexion maneuvers to direct the tube into the vocal cords first. On the other hand, cuff inflation maneuver must also be kept in mind.

Comparison of conventional fluid management with PVI-based goal-directed fluid management in elective colorectal surgery.

Intraoperative fluid management is quite important in terms of postoperative organ perfusion and complications. Different fluid management protocols are in use for this purpose. Our primary goal was to compare the effects of conventional fluid management (CFM) with the Pleth Variability Index (PVI) guided goal-directed fluid management (GDFM) protocols on the amount of crystalloids administered, blood lactate, and serum creatinine levels during the intraoperative period. The length of hospital stay was our secondary goal. Seventy ASA I-II elective colorectal surgery patients were randomly assigned to CFM or GDFM for fluid management. The hemodynamic data and the data obtained from ABG were recorded at the end of induction and during the follow-up period at 1 h intervals. In the preoperative period and at 24 h postoperatively, blood samples were taken for the measurement of hemoglobin, Na, K, Cl, serum creatinine, albumin and blood lactate. In the first 24 h after surgery, oliguria and the time of first bowel movement were recorded. Length of hospital stay was also recorded. Intraoperative crystalloid administration and urine output were statistically significantly higher in CFM group (p < 0.001, p: 0.018). The end-surgery fluid balance was significantly lower in Group GDFM. Preoperative and postoperative Na, K, Cl, serum albumin, serum creatinine, lactate and hemoglobin values were similar between the groups. The time to passage of stool was significantly short in Group-GDFM compared to Group-CFM (p = 0.016). The length of hospital stay was found to be similar in both group. PVI-guided GDFM might be an alternative to CFM in ASA I-II patients undergoing elective colorectal surgery. However, further studies need to be carried out to search the efficiency and safety of PVI.

[Ultrasound-guided penile nerve block for pediatric hypospadias surgery]. / Pediatrik hipospadias cerrahisinde ultrason rehberliginde penil blok uygulamasi.

An ultrasound-guided dorsal penile nerve (DPN) block was performed for postoperative analgesia in a 6-year-old, 19 kg, American Society of Anesthesiologists class II patient undergoing hypospadias surgery. The block was applied following the induction of general anesthesia. Anesthesia maintenance was provided with sevoflurane 2% in a 1:2 ratio of oxygen and nitrous oxide. The DPN block was performed using 0.2 mL/kg of 0.25% bupivacaine. Almost 24 hours of analgesia was provided following surgery.

Comparison of Univent tube and EZ blocker in one lung ventilation; airway pressures and gas exchange.

Univent tube (UT) and EZ-blocker were used for one-lung ventilation (OLV). UT is a single lumen tube with a small separate lumen containing a bronchial blocker. EZ-blocker differs with its unique y-shaped double-cuffed distal end. We aimed to compare these two airway devices effects on airway pressures, oxygenation, ventilation and haemodynamics during OLV. Patients undergoing elective thoracotomy for the first time were included in this prospective randomized study. Patients were divided into two groups as UT and EZ. Bronchial blockers (BB) placement time was recorded. In lateral decubitus position, airway pressures, static compliance, tidal volume (TV), respiratory rate (RR) and haemodynamic findings were recorded before inflating the BB cuff (Pre-OLV) and during OLV every 15 min. Arterial blood gas (ABG) samples were obtained before and during OLV. 70 patients were enrolled in the study. The demographic characteristics and data related to anesthesia and surgery were similar in both groups. It took longer to place EZ than UT (p = 0.02). Ppeak values were similar in both groups. Pplateau was significantly lower at the beginning of OLV (OLV15th min) and higher at the end of OLV (pre-DLV) in EZ group compared to UT (p = 0.01, p = 0.03). Cstatic were significantly higher at the beginning of OLV (OLV15th min) in EZ group compared to UT (p = 0.01). During the following measurements, Cstatic values were similar for both groups. Ventilation were achieved with similar TV and RR. ABG findings and haemodynamic variables were similar. EZ and Univent tube affected the airway pressures, oxygenation, ventilation and haemodynamic variables similarly during OLV in patients with normal respiratory function. These devices can be alternatives to each other based on clinical conditions.

Comparison of tidal volume and deep breath preoxygenation techniquesundergoing coronary artery bypass graft surgery: effects of hemodynamicresponse and arterial oxygenation

Background/aim: Different techniques exist for the preoxygenation of patients that will be operated on under general anesthesia. Preoxygenation with the deep breath (DB) method may affect cardiovascular stability, which is crucial for coronary artery bypass graft (CABG) patients. In this study, we aimed to compare the effects of the 3 min TVB preoxygenation technique and 1 min 8DBs technique on hemodynamic response and arterial oxygenation in patients with normal ejection fraction that were scheduled for elective CABG surgery. Materials and methods: Forty patients classified as ASA II?III and scheduled for elective CABG surgery were randomly assigned to TVB/3 min or 8DBs/1 min for preoxygenation. Cardiovascular variables, i.e. heart rate, mean arterial pressure, central venous pressure, cardiac index, systemic vascular resistance index, and stroke volume index, and arterial blood gas samples were analyzed before and after preoxygenation and at the end of the apneic period before intubation. Results: The preoxygenation methods affected the hemodynamic response similarly. PaO2 increased significantly with 8DBs compared to the TVB at the end of preoxygenation but was similar between the groups at the end of the apneic period (respectively, P: 0.03; P: 0.15). PaCO2 changes were similar between the groups. Conclusion: In patients with normal ejection fraction scheduled for CABG, 8DBs can be an alternative to TVB preoxygenation. Our results should be compared with those of other studies.
