Endobronchial Intubation With the King Vision® and McGrath® Laryngoscopes in Simulated Easy and Difficult Airways by Novices (eKingMath).

Objective. The competency of using video laryngoscopes (VL) for double-lumen tube (DLT) endobronchial intubations can be improved with constant training as assessed by measuring the learning curves. We hypothesized that the time to DLT intubation would be reduced over the intubation attempts. Design. A crossover manikin study. Settings. University-affiliated hospital. Participants. Forty-two novice medical students unfamiliar with DLT intubation. Interventions. Participants were randomly allocated to two sequences, including DLT intubation, using King Vision and McGrath VLs. Each participant completed 100 DLT intubation attempts on both simulated easy and difficult airways on two different mannikins using the study devices (25 attempts for each). Measurements and Main Results. The primary outcome was the time to DLT intubation. The secondary outcomes included the best glottic view, optimizing maneuvers, and intubation first-pass success. The use of King Vision VL was associated with a significantly shorter time to DLT intubation (P < 0.044 and P < 0.05, respectively) and a higher percentage of glottic opening (POGO) compared to the McGrath VL (P < 0.011 and P < 0.002, respectively) in the simulated "easy" and "difficult" over most of the intubation attempts. In the simulated "easy" airway, the first-pass success ratio was higher when using the King Vision VL (median [Minimum-Maximum] 100% [100%-100%] and 100% [88%-100%], P = 0.012). Conclusion. Novice medical students developed skills over intubation attempts, meaning achievement of a faster DLT intubation, better laryngeal exposure, and higher success rate on simulated "easy" and "difficult" airways. A median of 9 DLT intubations was required to achieve a 92% or greater DLT intubation success rate.

Assessment of patients' satisfaction with the postanesthesia care unit service at University Hospital in Al Khobar, KSA.

Objectives: The quality of health care is individually and subjectively reflected through patients' level of satisfaction, as well as the optimality and effectiveness of the provided postoperative pain management. The provision of postanesthesia care unit (PACU) service in hospitals has led to overall positive outcomes, in addition to the enhancement of patients' satisfaction with the provided pain management service. This study assessed patients' level of satisfaction with PACU service at a university hospital and discussed different factors that might have contributed to the level of satisfaction. Methods: A prospective cross-sectional study was carried out among patients after being discharged from PACU. The study took place at King Fahad Hospital of the University in Al Khobar, KSA between November 2021 and February 2022. The data were collected using a three-section predesigned questionnaire. Results: Two hundred patients were included in this study. Nearly all patients (95.5%) were satisfied with the provided pain management service. Almost all patients (99.5%) indicated that the PACU staff was courteous and professional during the entire pain management service. More patients complained about pain before using analgesia and this difference was statistically significant (Z = 8.642; p < 0.001). The satisfaction rate was significantly higher in the older age group (>45 years) (Z = 2.114; p = 0.035), in patients with American Society of Anesthesiology (ASA) 3 physical status (H = 13.130; p = 0.001), and those with a previous surgical history (Z = 2.139; p = 0.032). Conclusion: This study concluded that the level of patients' satisfaction with PACU service was high, and established a statistically significant association with age, ASA score, and previous surgical history. Healthcare providers should consider patient education and effective communication to increase patients' satisfaction level and improve the overall quality of care.

Effects of norepinephrine infusion during cardiopulmonary bypass on perioperative changes in lactic acid level (Norcal).

INTRODUCTION: Hyperlactatemia, a problem reported in up to 30% of cardiac surgery patients, results from excessive production of or decreased clearance of lactate. It is typically a symptom of tissue hypoperfusion and may be associated with the prevalence of postoperative acute mesenteric ischemia and renal failure, or prolonged intensive care unit (ICU) and hospital stay, and increased 30-day mortality. METHODS AND MEASUREMENTS: Eighty cardiac surgery patients using cardiopulmonary bypass (CPB) were randomly assigned into either a placebo (n = 39) or norepinephrine 0.05-0.2 µg/kg/min (n = 41) as well as norepinephrine boluses during CPB to maintain mean arterial blood pressure (MAP) at 65 to 80 mm Hg. Patient assignments were done after receiving ethical approval to proceed. The primary result was the perioperative changes in lactic acid level. Secondary findings were also recorded, including hemodynamic variables, the incidence of vasoplegia, intraoperative hypotension, myocardial ischemia, the need for vasopressor support, postoperative complications, and mortality. RESULTS: The peak levels and perioperative changes in blood lactate during the first 24 postoperative hours, the number of patients who experienced early hyperlactatemia on admission to the ICU (Placebo: 46.2%, Norepinephrine: 51.2%, p = .650), vasoplegia, hemodynamic changes, incidences of intraoperative hypotension, myocardial ischemia, postoperative complications, and mortality rates were similar in the two groups. Patients in the norepinephrine group received lower intraoperative rescue norepinephrine boluses to maintain the target MAP (p = .039) and had higher MAP values during the CPB and intraoperative blood loss [mean difference [95% confidence interval]; 177 [20.9-334.3] ml, p = .027]. CONCLUSION: norepinephrine and placebo infusions during the CPB with the maintenance of MAP from 65 to 80 mmHg had comparative effects on the changes in blood lactate and incidence of vasoplegia after cardiac surgery. Norepinephrine infusion maintained higher MAP values during the CPB.

Pain Knowledge and Attitude Survey among Health-care Professionals at a University Hospital in Saudi Arabia.

BACKGROUND: There is growing awareness in the hospital setting toward pain management to decrease patients' suffering, improve postsurgical outcomes and to decrease cost. OBJECTIVE: The aim of this study was to get an overview of the knowledge and attitude among health-care professionals toward pain management in the King Fahd Hospital of the University, and the need for an educational plan to improve pain service in hospitals. MATERIALS AND METHODS: We conducted a survey over a 3-month period based on a 30-question questionnaire to test pain knowledge and attitude among nurses and physicians of different specialties, the level of education and years of experience. RESULTS: The results of the data showed that knowledge and attitude of pain were deficient and unsatisfactory. CONCLUSION: We concluded that efforts to spread knowledge and education of proper pain management among health-care professionals are required. Further surveys involving more hospitals are warranted.

Evaluation of Pain Assessment Tools in Patients Receiving Mechanical Ventilation.

Pain assessment poses a great challenge for clinicians in intensive care units. This descriptive study aimed to find the most reliable, sensitive, and valid tool for assessing pain. The researcher and a nurse simultaneously assessed 47 nonverbal patients receiving mechanical ventilation in the intensive care unit by using 3 tools: the Behavioral Pain Scale (BPS), the Critical-Care Pain Observation Tool (CPOT), and the adult Nonverbal Pain Scale (NVPS) before, during, and after turning and suctioning. All tools were found to be reliable and valid (Cronbach α = 0.95 for both the BPS and the CPOT, α = 0.86 for the NVPS), and all subscales of both the BPS and CPOT were highly sensitive for assessing pain (P < .001). The NVPS physiology (P = .21) and respiratory (P = .16) subscales were not sensitive for assessing pain. The BPS was the most reliable, valid, and sensitive tool, with the CPOT considered an appropriate alternative tool for assessing pain. The NVPS is not recommended because of its inconsistent psychometric properties.

Multiple levels paravertebral block versus morphine patient-controlled analgesia for postoperative analgesia following breast cancer surgery with unilateral lumpectomy, and axillary lymph nodes dissection.

BACKGROUND: Postoperative pain after breast cancer surgery is not uncommon. Narcotic based analgesia is commonly used for postoperative pain management. However, the side-effects and complications of systemic narcotics is a significant disadvantage. Different locoregional anesthetic techniques have been tried including, single and multiple levels paravertebral block (PVB), which seems to have a significant reduction in immediate postoperative pain with fewer side-effects. The aim of this study was to compare unilateral multiple level PVB versus morphine patient-controlled analgesia (PCA) for pain relief after breast cancer surgery with unilateral lumpectomy and axillary lymph nodes dissection. MATERIALS AND METHODS: Forty patients scheduled for breast cancer surgery were randomized to receive either preoperative unilateral multiple injections PVB at five thoracic dermatomes (group P, 20 patients) or postoperative intravenous PCA with morphine (group M, 20 patients) for postoperative pain control. Numerical pain scale, mean arterial pressure, heart rate, Time to first analgesic demand, 24-h morphine consumption side-effects and length of hospital stay were recorded. RESULTS: PVB resulted in a significantly more postoperative analgesia, maintained hemodynamic, more significant reduction in nausea and vomiting, and shorter hospital stay compared with PCA patients. CONCLUSION: Multiple levels PVB is an effective regional anesthetic technique for postoperative pain management, it provides superior analgesia with less narcotics consumption, and fewer side-effects compared with PCA morphine for patients with breast cancer who undergo unilateral lumpectomy, with axillary lymph nodes dissection.

Successful management of complex regional pain syndrome type 1 using single injection interscalene brachial plexus block.

Complex regional pain syndrome (CRPS) type 1 of the upper limb is a painful and debilitating condition. Interscalene brachial plexus block (ISB) in conjugation with other modalities was shown to be a feasible therapy with variable success. We reported a case of CRPS type 1 as diagnosed by International Association for the Study of Pain criteria in which pharmacological approaches failed to achieve adequate pain relief and even were associated with progressive dysfunction of the upper extremity. Single injection ISB, in combination with physical therapy and botulinum toxin injection, was successful to alleviate pain with functional restoration.
