Pain Predictors in Patients in the Postanesthesia Care Unit.

PURPOSE: To analyze the effects of pain-predicting factors on patients in the postanesthesia care unit (PACU). DESIGN: This is an observational and prospective study. METHODS: This study was conducted at a University Hospital in the state of Minas Gerais (Brazil). To collect data on demographic, clinical, and surgical factors, a collection instrument was devised. The verbal numerical scale was employed to measure pain levels before and after surgery in the PACU. A path analysis was used to assess a predictive model. FINDINGS: A total of 226 patients were included in this study. The incidence of pain in the PACU was 31.9%. A model with demographic, clinical, and surgical variables was tested. The final model, after including modification indices, obtained results that indicated an acceptable data fit (comparative fit index = 0.996; root mean square error of approximation = 0.08). Age (being young), sex (being a woman), oncological diagnosis as an indication for the surgical procedure, type of surgery (surgery of the digestive system), duration of surgery (longer surgeries), and high intraoperative doses of opioids were predictive variables for pain in the PACU. CONCLUSIONS: This study's findings provide support for pain management in the PACU. Furthermore, the results of this research can be used to anticipate the occurrence of acute postoperative pain and personalized perioperative analgesia needs.

Association Between the Blood Glucose Value at PACU Discharge and Postoperative Hypoglycemia in Nondiabetic Patients With Hyperglycemia After Hysteroscopic Surgery: A Retrospective Cohort Study.

PURPOSE: The target glycemic control for nondiabetic patients in the postanesthesia care unit (PACU) after hysteroscopic surgery remains unclear. Our goal is to determine the optimal level of glycemic control by finding the relationship between blood glucose level (BGL) leaving the PACU and postoperative hypoglycemia in nondiabetic patients. DESIGN: This retrospective cohort study was conducted at a comprehensive tertiary hospital in Chongqing, China between June 2018 and December 2020. METHODS: The target independent and dependent variables were BGL leaving the PACU and postoperative hypoglycemia, respectively. The primary outcome was the incidence of hypoglycemia. Logistic regression was used to explore the association between discharge BGL and hypoglycemia. The optimal glycemic control range was determined by using the receiver operating characteristic (ROC) curve. FINDINGS: Prior to insulin use, BGL in the insulin-using subgroup might be as high as 20 mmol/L. Hypoglycemia was related to the BGL while leaving the PACU (odds ratio (OR) 0.37 [95% confidence interval (CI) 0.22 to 0.65]). The best cut-off value (12.95 mmol/L) was determined by fitting the ROC curve. CONCLUSIONS: If severe hyperglycemia develops during hysteroscopic surgery in individuals with 5% glucose as the mediator of uterine distention, the recommendation is to maintain blood glucose above 12.95 mmol/L when treated with insulin.

Implementation Science: Incorporating Obstructive Sleep Apnea Screening and Capnography Into Everyday Practice.

PURPOSE: This article describes the implementation and maintenance of obstructive sleep apnea (OSA) screening and capnography monitoring. DESIGN: A quality improvement project. METHODS: A multidisciplinary team provided staff education to three perianesthesia care units. Using the STOP-Bang screening tool, five or more positive responses indicated high risk for OSA. A postanesthesia care unit audit tool tracked STOP-Bang scores, capnography use, hypoventilation events, nursing interventions, and respiratory complications. FINDINGS: Among 314 patients with OSA, 36% were identified as high risk. Nurses used capnography on 76% of OSA patients and were able to readily identify hypoventilation and intervene. Respiratory complications occurred in 10.8% (n = 34) requiring a higher level of care. Postimplementation, all six postanesthesia care units employ this best practice. CONCLUSIONS: Perianesthesia nurses found OSA screening and capnography easy to incorporate into nursing practice. This process can reduce respiratory complications in the surgical patient with OSA. An Evidence-Based Practice Fellowship Program facilitated this practice change.

Decreasing the Incidence of Postoperative Urinary Retention and Incontinence With Total Joint Replacement Patients After Spinal Anesthesia in the Postanesthesia Care Unit: A Quality Improvement Project.

PURPOSE: Patients with postoperative urinary retention (POUR) can develop bladder atrophy, urinary incontinence, and hypertension. The purpose of this quality improvement project was to implement standardized guidelines for bladder scanning for patients who have total knee or hip replacement to decrease POUR and incontinent episodes. DESIGN: A retrospective descriptive study was implemented in a 425-bed Magnet community hospital. METHODS: Patients were bladder scanned within the first hour of postanesthesia care unit admission. Straight catheterization was performed for those who had more than 400 mL of retained urine. The protocol included both total knee and total hip replacement surgeries with spinal anesthesia. Compliance with scanning, percentages with POUR, and incontinent episodes were reviewed. FINDINGS: POUR was detected in 46% of total knee replacement patients and 36% of total hip replacement patients. Incontinence rates for knee replacement patients decreased by 14% and by 2% for patients with total hip replacements. CONCLUSIONS: A bladder scanning protocol decreases postoperative incontinence. Bladder scanning also helps to decrease POUR by decreasing the potential risk of complications.

Implementation of an Obstructive Sleep Apnea Protocol in the Postanesthesia Care Unit for Patients Undergoing Spinal Fusion Surgery.

PURPOSE: The purpose of this project was to implement and evaluate the effectiveness of a postanesthesia care unit (PACU) obstructive sleep apnea (OSA) protocol in patients undergoing spinal fusion surgery. DESIGN: The structure of this project was a preimplementation and postimplementation design. METHODS: A convenience sample of 63 patients admitted to the PACU after spinal fusion surgery, with diagnosed or high-risk OSA, was included in protocol implementation. FINDINGS: The prevalence of diagnosed and high-risk OSA at the project implementation site totaled 74% in the spinal fusion population. The incidence of oxygen desaturations was 41% in the preimplementation group and 35% in the postimplementation group. The PACU to intensive care unit transfers were 10% in the preimplementation group and 3% in the postimplementation group. CONCLUSIONS: Protocols for surgical patients with OSA require further examination but may function as a guide for postoperative nursing care.

Estimating Respiratory Rate in Post-Anesthesia Care Unit Patients Using Infrared Thermography: An Observational Study.

The post-anesthesia care unit (PACU) is the central hub for recovery after surgery, especially when the surgery is performed under general anesthesia. Aside from clinical aspects, respiratory impairment is one of the major causes of morbidity and affected recovery in the PACU and should therefore be monitored. In previous studies, infrared thermography was applied to assess the breathing rate (BR) of healthy volunteers. Here, the transferability of published methods for postoperative patients in the PACU was examined. Video recordings of 28 patients were acquired using a long-wave infrared camera, and analyzed offline. For validation purposes, BRs derived from body surface electrocardiography were measured simultaneously. In general, a close agreement between the two techniques (r = 0.607, p = 0.002 upon arrival, and r = 0.849, p < 0.001 upon discharge from the PACU) was obtained. In conclusion, the algorithm was demonstrated to be feasible and reliable under these challenging conditions.

Nicotine addiction management following surgery: a quality improvement approach in the post anesthesia care unit.

QUALITY PROBLEM: For smokers, hospital admission is accompanied by forced involuntary nicotine abstinence due to smoke-free site/grounds policies. An audit of patients admitted to our surgical wards revealed that identification of smoking status was inadequate and that nicotine addiction management (NAM) was infrequently offered. The project aimed to enhance both these metrics by initiating NAM in the post anesthesia care unit (PACU). INITIAL ASSESSMENT: Out of 744 patients admitted to our PACU in August 2015, 54% had their smoking status documented. The 200 patients (27%) out of the 744 were smokers and only 50% were offered NAM before discharge. CHOICE OF SOLUTION: PACU unit staff to determine the smoking status of every patient before discharge from the PACU (later changed to OR nursing staff) and, if a patient was identified as a smoker, to offer NRT (patch and mouth spray only) and initiate therapy prior to transfer of the patient to the ward. IMPLEMENTATION: Data about number of patients admitted, presence of documented smoking status, number of identified smokers, and number offered/accepted nicotine replacement therapy (NRT) were collected at baseline and thereafter quarterly. Engaging video education sessions addressed the education gaps highlighted in a needs assessment. Identification of smoking status was made part of preoperative checklist and NRT was made available in post-operative recovery room. RESULTS: These interventions resulted in an increase in screening for tobacco use from 54% at baseline to 95% and the offer of NRT to smokers from 50 to 89%.

Perceived Needs, Preparedness, and Emotional Distress of Male Caregivers of Postsurgical Women With Gynecologic Cancer

OBJECTIVES: To describe the perceived needs, preparedness, and emotional distress of male caregivers of postsurgical patients with gynecologic cancer during the transition from hospital to home. 
. SAMPLE & SETTING: 50 male caregivers of patients with gynecologic cancer on an inpatient unit at University Hospitals Seidman Cancer Center in Cleveland, OH.
. METHODS & VARIABLES: Caregiver needs, perceived preparedness, and emotional distress were measured at admission and at one week postdischarge. Instruments included the Comprehensive Needs Assessment Tool for Cancer Caregivers, Preparedness for Caregiving Scale, and National Comprehensive Cancer Network Distress Thermometer. The analysis consisted of descriptive statistics, Spearman's correlations, and univariate linear regressions.
. RESULTS: At both time points, male caregivers' greatest needs were interaction with the healthcare staff and information. Perceived preparedness was not associated with emotional distress. Male caregivers who were young, were employed, were unmarried, and had a lower income had greater needs.
. IMPLICATIONS FOR NURSING: A relational nursing care approach that maintains effective communication with male caregivers is essential. Nurses should broaden the caregiver assessment beyond the practical care of the patient.

Examining IV Insulin Practice Guidelines in the Cardiac Surgery Patient: Nurses Evaluating Quality Outcomes.

Recent changes in the Surgical Care Improvement Project guideline require blood glucose values be less than 180 mg/dL 18 to 24 hours after anesthesia end time after cardiac surgery. Our study compares the first group of patients transitioned off IV insulin on postoperative day 1, 24 hours after anesthesia end time, whereas the second group was transitioned off IV insulin on the second day, 48 hours after anesthesia end time. Results show no statistical difference in outcomes between groups.

Improvement of nutritional care after colon surgery: the impact of early oral nutrition in the postanesthesia care unit.

PURPOSE: The purpose of this study was to evaluate the impact of implementing early oral nutritional supplements in the postanesthesia care unit (PACU) after colon surgery. DESIGN: A randomized controlled intervention study. METHODS: Patients admitted for elective colon surgery were randomly assigned to either a group receiving early oral nutritional supplements (n=24) or traditional treatment with water or lemonade (n=22) in the PACU. FINDING: On the second postoperative day, patients in the early nutritional supplement group had a higher cumulative intake of energy (P=.019) and protein (P=.015) compared with the traditional treatment. Postoperative nausea and vomiting, pain, length of stay in the PACU, and need of a nasogastric tube did not differ significantly between the groups. CONCLUSIONS: The nutritional course for patients undergoing colon surgery can be improved by implementing early oral nutritional supplements in the PACU.

Incidence of arrhythmias in ASA I patients in the phase I PACU.

Cardiac monitoring is routinely performed on all adult patients in the immediate postoperative period in the Phase I PACU, regardless of the surgery/procedure or type of anesthesia given. This practice is based on the premise that there may be a possibility of a postanesthesia arrhythmia or cardiac event that would need to be recognized and treated. The purpose of this study was to explore whether routine cardiac monitoring is a valid practice for healthy individuals (ASA I) or merely a tradition of postanesthesia nursing care.

Pain assessment tool in the critically ill post-open heart surgery patient population.

Critical-care patients are at higher risk for untreated pain, because they are often unable to communicate owing to altered mental status, mechanical ventilation, and sedation. Pain that is persistent and untreated affects most body systems and results in development of complications chronic pain, and increased length of stay. This descriptive repeated-measures study compared three pain assessment tools in nonverbal critically ill patients in a cardiac postanesthesia care unit (n=24). Tools included the Critical-Care Pain Observation Tool (CPOT), adult Nonverbal Pain Scale (NVPS), and the Faces, Legs, Activity, Cry, and Consolability scale (FLACC). Two painful events, suctioning and repositioning, were studied. Data were collected immediately before the event, 1 minute after, and 20 minutes after. Both the CPOT and the NVPS demonstrated high reliability (Cronbach alpha coefficients 0.89). The NVPS and the CPOT were highly correlated for both raters (r>0.80, p=.00) (11 out of 12 times). Correlations between the two raters was generally moderate to high, but higher with the CPOT. There was more disagreement between raters in overall pain scores for the NVPS. When raters disagreed, it was most often in rating the face component on both scales. Disagreement was highest during the event. Both scales adequately capture pain in the nonverbal sedated critically ill patient based on assessment of patients' face, body movements, muscle tension, and respirations, with the NVPS also considering vital signs. Pictures depicting facial expressions for scoring purposes are helpful. Adequate education and understanding of use of the scales is critical for accurate assessment and subsequent interventions.

Patient assessment in recovery.

Recovery rooms hold an undeniably important place in the perioperative journey for the patient. It is here that possible complications following anaesthesia or surgery can be detected and rectified and patients can be made comfortable before returning to the ward. This article explores the vital aspects of patient assessment which are important for any recovery practitioner to consider.

Vision loss as a complication of nonophthalmologic surgery: implications for care for the perianesthesia nurse.

Postoperative vision loss not associated with ophthalmic surgery is a topic that has emerged in recent literature. Although presentation of this complication is rare, perianesthesia nurses should update their knowledge base to include knowledge of these devastating events. A review of common ocular events associated with postoperative vision loss, and the symptoms, assessment, management, and treatment of these events are indicated. The aim of this article is to explore the process of postoperative vision loss and present useful strategies to nurses for optimization of perianesthesia care.

Anesthesia for children with hyperleukocytosis a retrospective review.

BACKGROUND: Hyperleukocytosis (a white cell count in peripheral blood >100 x 10(9) l(-1)) is a well-recognized medical emergency. Rates of morbidity associated with anesthesia in hyperleukocytotic patients have not been previously described. This retrospective study describes the perioperative morbidity and mortality of children who present acutely with hyperleukocytosis. METHODS: All patients under 17 years of age with leukemia complicated by hyperleukocytosis and who received general anesthesia as part of their acute care at the Children's Hospital in Westmead from July 1999 to June 2008 were included. Data describing perioperative adverse events within 48 h of anesthesia were collected using a systematic chart review. RESULTS: Over the 8- year period, 60 children were admitted with hyperleukocytosis related to a new diagnosis of leukemia. Fifty-two children had general anesthesia within 48 h of their admission. Eleven children required two separate general anesthetics within this same time frame. Two deaths were recorded within 48 h of anesthesia; one child died from neurological complications of her disease, and the second died from multi-organ failure. Three children had serious respiratory adverse events requiring postanesthesia intensive care. Thirteen children had notable but less serious adverse events. These were typically respiratory in nature and required supplemental oxygen for more than 2 h after anesthesia. CONCLUSION: Children with leukemia-related hyperleukocytosis often require general anesthesia at the time of presentation and are at significant perioperative risk. Respiratory adverse events are very common and mandate close postanesthesia care.

Parental presence on emergence: effect on postanesthesia agitation and parent satisfaction.

This prospective, randomized study compared the incidence and duration of postanesthetic agitation in children whose parents were present or absent during emergence from anesthesia. Findings demonstrated that there was no difference in agitation between groups; however, more parents who were present believed they were present at "the right time," in contrast to those reunited later, who more often said they arrived "too late." Furthermore, these parents were comfortable in the setting and reported a high degree of helpfulness in comforting their child. Findings from this study suggest that although parental presence at emergence did not decrease agitation in young children, there was significant psychosocial benefit to the parents. Perioperative and perianesthesia nurses should consider these potential benefits when planning reunion of parents with their children after surgery.

Pain assessment and management in patients after abdominal surgery from PACU to the postoperative unit.

The aim of this exploratory study was to determine the effectiveness of pain relief for surgical patients (N = 52) in transition from the PACU to the postoperative unit. The study also explored whether there was an association between a verbal numeric pain score (0 to 10) on discharge from the PACU and the duration of time until analgesia was administered in the postoperative unit. Information was obtained about pain management, time of discharge, and patient pain scores on discharge from the PACU, as well as pain scores and the time of first analgesic administered in the postoperative unit. Most patients were discharged from the PACU with a pain score in the mild range (0 to 4), indicating reasonable pain relief. An association existed between the pain score on discharge from the PACU and the duration of time to the first analgesic dose administered on the postoperative unit.

Accuracy and reliability of continuous blood glucose monitor in post-surgical patients.

BACKGROUND: The STG-22 is the only continuous blood glucose monitoring system currently available. The aim of this study is to determine the accuracy and reliability of the STG-22 for continuously monitoring blood glucose level in post-surgical patients. METHODS: Fifty patients scheduled for routine surgery were studied in surgical intensive care unit (ICU) of a university hospital. After admission to the ICU, the STG-22 was connected to the patients. An attending physician obtained blood samples from a radial arterial catheter. Blood glucose level was measured using the ABL800FLEX immediately after blood collection at 0, 4, 8, and 16 h post-admission to the ICU (total of 200 blood glucose values). RESULTS: The correlation coefficient (R2) was 0.96. In the Clarke error grid, 100% of the paired measurements were in the clinically acceptable zone A and B. The Bland and Altman analysis showed that bias+/-limits of agreement (percent error) were 0.04(0.7)+/-0.35(6.3) mmol (mg/dl) (7%), -0.11(-2)+/-1.22(22) (15%) and -0.33(-6)+/-1.28(23) (10%) in hypoglycemia (<70(3.89) mmol (mg/dl), normoglycemia (3.89(70)-10(180) mmol (mg/dl), and hyperglycemia (>10(180) mmol (mg/dl), respectively. CONCLUSIONS: The STG-22 can be used for measuring blood glucose level continuously and measurement results are consistent with intermittent measurement (percentage error within 15%). Therefore, the STG-22 is a useful device for monitoring in blood glucose level in the ICU for 16 h.
