Postoperative outcomes of purely laparoscopic donor hepatectomy compared to open living donor hepatectomy: a preliminary observational study

Purpose@#To lessen the physical, cosmetic, and psychological burden of donors, purely laparoscopic donor hepatectomy (PLDH) has been proposed as an ideal method for living donors. Our study aimed to prospectively compare the effect of PLDH and 2 other types of open living donor hepatectomy (OLDH) on postoperative pain and recovery. @*Methods@#Sixty donors scheduled to undergo donor hepatectomy between March 2015 and November 2017 were included.Donors were divided into 3 groups by surgical technique: OLDH with a subcostal incision (n = 20), group S; OLDH with an upper midline incision (n = 20), group M; and PLDH (n = 20), group L. The primary outcomes were postoperative pain and analgesic requirement during postoperative day (POD) 3. Other variables regarding postoperative recovery were also analyzed. @*Results@#Although pain relief during POD 3, assessed by visual analog scale (VAS) score and analgesic requirement, was similar among the 3 groups, group L showed lower VAS scores and opioid requirements than group M. Moreover, group L was associated with a rapid postoperative recovery evidenced by the shorter hospital length of stay and more frequent return to normal activity on POD 30. @*Conclusion@#This pilot study failed to verify the hypothesis that PLDH reduces postoperative pain. PLDH did not reduce postoperative pain but showed faster recovery than OLDH.

Comparison of intrathecal morphine and surgical-site infusion of ropivacaine as adjuncts to intravenous patient-controlled analgesia in living-donor kidney transplant recipients

<p><b>INTRODUCTION</b>This prospective observational study compared the postoperative analgesic effectiveness of intrathecal morphine (ITM) and surgical-site infusion (SSI) of ropivacaine as adjuncts to intravenous (IV) patient-controlled analgesia (PCA) (fentanyl) in living-donor kidney transplant recipients.</p><p><b>METHODS</b>Patients undergoing living-donor kidney transplantation who received ITM or SSI in addition to IV PCA were included. Rescue analgesia was achieved with IV meperidine as required. The primary outcome, measured using the Numeric Pain Rating Scale (NRS), was pain at rest and when coughing. Patients were assessed for 48 hours after surgery.</p><p><b>RESULTS</b>A total of 53 patients (32 ITM, 21 SSI) were included in the study. The ITM group showed significantly lower NRS scores, at rest and when coughing, for up to 12 and eight hours. NRS scores were comparable between the groups at other times. The ITM group had significantly less postoperative systemic opioid requirement in the first 24 hours, but there was no significant difference between the systemic opioid consumption of the groups on postoperative Day 2. In the ITM group, 3 (9.4%) patients presented with bradypnoea and 1 (3.1%) with excessive sedation in the first 12 postoperative hours. More patients in the ITM group developed pruritus requiring treatment during the first 24 hours. There were no differences between the groups in other outcomes (e.g. nausea/vomiting, change in pulmonary or kidney functions).</p><p><b>CONCLUSION</b>Compared with SSI, ITM reduced immediate postoperative pain and IV opioid consumption on postoperative Day 1 after living-donor kidney transplantation, but at the cost of increased pruritus and respiratory depression.</p>

Accidental left atrial appendage thrombus detected by intraoperative transesophageal echocardiography during coronary artery bypass graft: A case report

A 77-year-old woman was scheduled for a coronary artery bypass graft. Her preoperative transthoracic echocardiographic (TTE) examination revealed an enlarged left atrium with reduced systolic dysfunction (ejection fraction: 38%), moderate global hypokinesia of the left ventricle, and moderate mitral and tricuspid regurgitation. No thrombus was visualized on the preoperative TTE. However, the intraoperative transesophageal echocardiography performed before the cardiopulmonary bypass revealed a thrombus of approximately 1.3 × 1.8 cm in the left atrial appendage (LAA). The LAA thrombus was removed, an internal suture was placed on the LAA before the coronary artery bypass grafting, and the main operation was performed successfully. The patient was transferred to the intensive care unit to receive postoperative care. She was extubated 4 h after the surgery and was transferred to the general ward on postoperative day 3 without any neurological sequelae.

Randomized trial of subfascial infusion of ropivacaine for early recovery in laparoscopic colorectal cancer surgery / 대한마취과학회지

BACKGROUND: There is a need for investigating the analgesic method as part of early recovery after surgery tailored for laparoscopic colorectal cancer (LCRC) surgery. In this randomized trial, we aimed to investigate the analgesic efficacy of an inverse ‘v’ shaped bilateral, subfascial ropivacaine continuous infusion in LCRC surgery. METHODS: Forty two patients undergoing elective LCRC surgery were randomly allocated to one of two groups to receive either 0.5% ropivacaine continuous infusion at the subfascial plane (n = 20, R group) or fentanyl intravenous patient controlled analgesia (IV PCA) (n = 22, F group) for postoperative 72 hours. The primary endpoint was the visual analogue scores (VAS) when coughing at postoperative 24 hours. Secondary end points were the VAS at 1, 6, 48, and 72 hours, time to first flatus, time to first rescue meperidine requirement, rescue meperidine consumption, length of hospital stay, postoperative nausea and vomiting, sedation, hypotension, dizziness, headache, and wound complications. RESULTS: The VAS at rest and when coughing were similar between the groups throughout the study. The time to first gas passage and time to first rescue meperidine at ward were significantly shorter in the R group compared to the F group (P = 0.010). Rescue meperidine was administered less in the R group; however, without statistical significance. Other study parameters were not different between the groups. CONCLUSIONS: Ropivacaine continuous infusion with an inverse ‘v ’ shaped bilateral, subfascial catheter placement showed significantly enhanced bowel recovery and analgesic efficacy was not different from IV PCA in LCRC surgery.

Awake endotracheal intubation using a video-assisted intubating stylet in a patient with a large supraglottic mass: A case report

A 70-year-old man was scheduled for laryngeal microsurgery for supraglottic tumor. A preoperative indirect laryngoscopy demonstrated a large tumor obstructing the most of glottic opening. To prevent damage to the tumor during advancement of the endotracheal tube (ETT), an awake intubation assisted by Clarus Video System (CVS), was planned. Ten percent lidocaine spray was applied to the oropharynx. After sufficient preoxygenation, the patient was lightly sedated with continuous remifentanil and propofol infusion. The CVS, loaded with an ETT (inner diameter of 5.5 mm), was inserted orally by the anesthesiologist. The tube was carefully slid off the stylet into the glottic opening under direct vision. The anesthesiologist also confirmed that there was no damage to the tumor during intubation.

Analysis of predictive factors for difficult ProSeal laryngeal mask airway insertion and suboptimal positioning

BACKGROUND: There has been controversy about predicting difficult LMA insertion and suboptimal position. Our aim was to evaluate bedside predictors for difficult LMA ProSeal(TM) (PLMA) insertion and suboptimal position. METHODS: As the potential predictive factors for difficult PLMA insertion and suboptimal position, we considered male gender, increased body mass index (BMI), seven individual items suggesting difficult airway [modified Mallampati classification > or = III, inter-incisor distance or = moderate, upper lip bite test (ULBT) > or = II] and > or = 3 of total airway score which is the sum of scores assessed by a score of 0, 1, 2 in seven individual items. The PLMA position was assessed by fiberoptic bronchoscopy to determine whether these predictors predict suboptimal position of PLMA (fiberoptic score or = 3 indicates suboptimal position of PLMA.

Comparison of the ease of laryngeal mask airway ProSeal insertion and the fiberoptic scoring according to the head position and the presence of a difficult airway / 대한마취과학회지

BACKGROUND: The sniffing position is recommended for conventional laryngeal mask airway (LMA) insertion. However, there has been a high success rate of LMA insertion with the head in the neutral position. The effect of a difficult airway on the ease of LMA insertion is not clear. In this study, we compared the ease of LMA ProSeal(TM) (PLMA) insertion and the fiberoptic scoring according to the head position and the presence of a difficult airway. METHODS: After obtaining informed consent from the subjects, we enrolled 144 adult patients (age range: 18-65) with an ASA physical status 1 or 2. After evaluation of the airway, all the patients were grouped into the EA (easy airway) group (n = 68) and the DA (difficult airway) group (n = 76). According to the head position, each group was divided into the EA-SE (extension) group (n = 35), the EA-SN (sniffing) group (n = 33), the DA-SE group (n = 39) and the DA-SN group (n = 37). The success rate and insertion time at the first attempt were evaluated. The position of the PLMA was fiberoptically scored from the mask aperture of the airway tube in the original head position. After the head position was changed to the sniffing and neutral positions in the SE and SN group, respectively, the position of PLMA was re-evaluated fiberoptically. RESULTS: The success rate and insertion time at the first attempt and the fiberoptic score showed no significant difference among the groups. After head position was changed, there were no significant changes in the fiberopitc scores. CONCLUSIONS: A difficult airway and the head position had no influence on the ease of PLMA insertion and the fiberopic score. Therefore, the head position can be selected according to the individual patient's situation.

The effect of different oxygen administration under combined spinal-epidural anesthesia for cesarean section / 대한마취과학회지

BACKGROUND: During cesarean section under regional anesthesia, it is current practice to provide the parturient with a source of supplemental oxygen. We compared the effect of high flow oxygen by mask with that of low flow oxygen by nasal prongs. METHODS: Fifty eight parturients presenting for elective cesarean section under combined spinal-epidural anesthesia were randomly assigned to one of the three groups to be given either oxygen 4 L/min by mask, oxygen 8 L/min by mask or oxygen 2 L/min by nasal prongs. Umbilical arterial and venous blood samples were taken and analysed immediately after delivery. RESULTS: There were no significant differences in the umbilical arterial or venous pH, partial pressure of oxygen and partial pressure of carbon dioxide among the three groups. In neonatal outcome, there were no differences in Apgar scores. CONCLUSIONS: It Makes No Differences Whether The Parturients Received Supplemental Oxygen By Nasal Prongs Or Simple Face Mask During Cesarean Section Under Combined Spinal-epidural Anesthesia.

Pneumocephalus Developed during Epidural Anesthesia for Combined Spinal-Epidural Anesthesia

The superiority of air versus saline for identifying the epidural space remains unestablished. Epidural anesthesia using a loss of resistance technique (LORT) with air is associated with increasing complications of dural puncture-induced headaches and neurological and hemodynamic changes. Here, we described a case of pneumocephalus with a large amount of air that was accompanied by severe headache and nuchal and chest pain occurring after epidural block using LORT with air for combined spinal-epidural anesthesia.
