Cognitive Assessment of Surgeons During Surgical Procedures: Influence of Time and Intraoperative Complications.

INTRODUCTION: Surgeon's performance may be influenced by several factors that may affect skills and judgement, which ultimately represents surgeon´s cognition. Cognition refers to all forms of knowing and awareness, such as perceiving, conceiving, remembering, reasoning, judging, imagining, and problem solving. This report aims to evaluate the effect of operative time and operative complications on surgeon´s cognition. METHODS: Forty-six surgeons (mean age 31 years, 78% males) assigned to an operation expected to last for at least 2 h, volunteered for the study. All participants underwent 3 cognitive tests at the beginning of the operation and hourly, until the end of the procedure: (a) concentration (serial sevens, counting down from 100 by sevens); (b) visual (fast counting, counting the number of circles with the same color among a series of circles); and (c) motor (trail making, connecting a set of numbered dots). Intraoperative complications were recorded. RESULTS: The visual test had a stable behavior along time. Concentration and motor tests tend to be performed faster. Intraoperative complications occurred in 5 (11%) cases (3 hemorrhage and 2 organ injuries). Performance time was stable for concentration and motor tests but visual test tends to be performed faster in cases with an intraoperative complication. CONCLUSION: Our results showed that (1) time does not jeopardize surgeons' cognition, but rather surgeons learned to perform the tests faster, and (2) complications do not decrease surgeons' cognition.

Opioid analgesia and the somatosensory memory of neonatal surgical injury in the adult rat.

BACKGROUND: Nociceptive input during early development can produce somatosensory memory that influences future pain response. Hind-paw incision during the 1st postnatal week in the rat enhances re-incision hyperalgesia in adulthood. We now evaluate its modulation by neonatal analgesia. METHODS: Neonatal rats [Postnatal Day 3 (P3)] received saline, intrathecal morphine 0.1 mg kg-1 (IT), subcutaneous morphine 1 mg kg-1 (SC), or sciatic levobupivacaine block (LA) before and after plantar hind-paw incision (three×2 hourly injections). Six weeks later, behavioural thresholds and electromyography (EMG) measures of re-incision hyperalgesia were compared with an age-matched adult-only incision (IN) group. Morphine effects on spontaneous (conditioned place preference) and evoked (EMG sensitivity) pain after adult incision were compared with prior neonatal incision and saline or morphine groups. The acute neonatal effects of incision and analgesia on behavioural hyperalgesia at P3 were also evaluated. RESULTS: Adult re-incision hyperalgesia was not prevented by neonatal peri-incision morphine (saline, IT, and SC groups > IN; P<0.05-0.01). Neonatal sciatic block, but not morphine, prevented the enhanced re-incision reflex sensitivity in adulthood (LA < saline and morphine groups, P<0.01; LA vs IN, not significant). Morphine efficacy in adulthood was altered after morphine alone in the neonatal period, but not when administered with neonatal incision. Morphine prevented the acute incision-induced hyperalgesia in neonatal rats, but only sciatic block had a preventive analgesic effect at 24 h. CONCLUSIONS: Long-term effects after neonatal injury highlight the need for preventive strategies. Despite effective analgesia at the time of neonatal incision, morphine as a sole analgesic did not alter the somatosensory memory of early-life surgical injury.

Prospective study on the outcome of the sphenoid drill out procedure.

BACKGROUND: Chronic sphenoid sinusitis refractory to both medical therapy and sphenoidotomy requires a more extended intervention based on the principles of salvage surgery. Our aim is to describe the sphenoid drill out technique as a sphenoid salvage intervention and to outline its implications on clinical outcome and quality of life. METHODOLOGY: 12 patients with chronic sphenoiditis undergoing a sphenoid drill out procedure were examined by nasal endoscopy preoperatively and postoperatively for one year. Preoperative and postoperative quality of life questionnaires (RSOM-31 and SF-36) were obtained. RESULTS: All but one patient had a completely patent neostium without scar formation. No major complications occurred after this procedure. All patients reported at least an improvement of their symptoms, 50% of patients were even symptom free at one year after surgery. The median postoperative RSOM-31 score was significantly lower than the preoperative score. Both the physical component summary (PCS) and the mental component summary (MCS) of the SF-36 score improved significantly. None of the patients needed a revision procedure. CONCLUSION: Sphenoid drill out is a safe and effective technique with a high success rate. In patients with chronic sphenoid sinusitis refractory to medical therapy and surgery it could be a valid alternative to revision sphenoidotomy.

Intraoperative medial joint laxity in flexion decreases patient satisfaction after total knee arthroplasty.

INTRODUCTION: The relationship between postoperative tibiofemoral ligament balance and patient satisfaction in total knee arthroplasty (TKA) has been explored previously. However, the optimal intraoperative medial-lateral ligament balance during knee flexion in terms of postoperative patient satisfaction remains unknown. We evaluated the effect of intraoperative flexion instability on patient satisfaction after TKA. MATERIALS AND METHODS: This study consisted of 46 knees with varus osteoarthritis undergoing TKA. Medial-lateral component gaps at 0° knee extension and 90° flexion were measured intraoperatively using a knee balancer. Differences in postoperative patient outcomes at 3 weeks and 1 year were compared between medially tight knees in 90° flexion with a medial component gap of < 4 mm and medially loose knees in 90° flexion with a gap of ≥ 4 mm. Outcomes were measured using the 2011 Knee Society Scoring System (2011 KS). RESULTS: The median total 2011 KS score at 1 year postoperatively in the medially loose knees [median 97; interquartile range (IQR) 75-117] was significantly lower than that in the medially tight knees (median 128; IQR 104-139, P < 0.01), while preoperative and 3-week postoperative scores were similar. In addition, medial flexion gaps were not significantly associated with total 2011 KS scores before surgery or at 3 weeks postoperatively. However, at 1 year after surgery, medial component flexion gaps were negatively associated with the total 2011 KS score (R = - 0.42; P < 0.01) and the 2011 KS satisfaction subscale score (R = - 0.36; P = 0.01). CONCLUSIONS: Excessive intraoperative medial joint laxity of ≥ 4 mm at 90° flexion progressively decreased patient satisfaction for 1 year. Since intraoperative medial laxity in flexion is likely to interfere with functional recovery after TKA, medial stabilization during TKA is important throughout knee flexion. LEVEL OF EVIDENCE: Therapeutic study, Level III.

Pain as performance: re-virginisation in Turkey.

The literature on pain has so far been primarily interested in chronic pain, medically induced pain and pain as an unwanted experience. However, pain is a more complicated experience and the lines between pain and pleasure are blurred in different contexts. In this paper, these lines are explored within the context of re-virginisation in Turkey by taking to its centre the meanings attached to pain through women's online and offline narratives. Re-virginisation refers to the process women undergo in order to reclaim their virginity due to the expectation that women should be virgins at the time of marriage and to the persistence of the myth that virginity can and should be proved via bleeding during or right after sexual intercourse.Based on semi-structured in-depth interviews and phenomenological and post-structuralist discourse analysis of online data, I argue that pain in the process of re-virginisation (1) is desired and sought-after and (2) is a gendered and temporospatial performance. Within this performance, pain manifests itself as a functional experience as well, especially as a marker of having been operated on, of having had a successful operation, as a reminder of this operation, and finally as an experience around which a community can be formed. Although pain can be functional at most stages of re-virginisation, when, where, and how it can be performed is determined intersubjectively.

Salivary Alpha Amylase, Dental Anxiety, and Extraction Pain: A Pilot Study.

The primary intention of this study was to determine whether salivary alpha-amylase (sAA) factors or the Dental Anxiety Scale (DAS) was a better predictor of dental extraction pain. This study followed a cross-sectional design and included a convenience sample (n = 23) recruited from an outpatient oral surgery clinic. While waiting for their scheduled appointments, consenting patients completed both basic demographic/medical history questionnaires and Corah's DAS as well as submitted sublingual saliva samples. After their extractions, patients marked visual analog scales (VAS) to indicate the intensity of their intraoperative discomfort. Results of this study confirm that there is a relationship between a patient's dental anxiety and intraoperative extraction pain (r[21] = .47, P = .02). This study did not find that preoperative sAA factors (concentration and output rate) were related to either VAS extraction pain or DAS score. A strong positive relationship was observed between the concentration of sAA and the rate of sAA output (r[21] = .81, P < .001). Based on the results of our study, we conclude that dental anxiety has a moderate but significant correlation with intraoperative dental pain. Factors of sAA do not appear to be predictive of this experience. Therefore, simply assessing an anxious patient may be the best indication of that patient's extraction pain.

Dexmedetomidine Combined with General Anesthesia Provides Similar Intraoperative Stress Response Reduction When Compared with a Combined General and Epidural Anesthetic Technique.

BACKGROUND: Epidural anesthesia may attenuate the sympathetic hyperactivity and stress response from surgery. In this study, we compared the stress response, hemodynamic variables, and recovery profiles of patients undergoing total IV anesthesia (TIVA) and intraoperative dexmedetomidine with those receiving epidural anesthesia and TIVA. METHODS: Ninety patients undergoing elective open gastrectomy under TIVA were recruited. The dexmedetomidine group (group D, n = 30) received IV dexmedetomidine 0.6 µg/kg before the induction of general anesthesia, followed by dexmedetomidine 0.4 µg/kg/h until peritoneal closure. The control group (group C, n = 30) received volume-matched normal saline infusion as placebo. The epidural group (group E, n = 30) received epidural anesthesia with 0.375% ropivacaine combined with TIVA. The hemodynamic variables and recovery characteristics during emergence were evaluated. Blood samples for norepinephrine (NE), epinephrine (E), cortisol (Cor), and cytokines (tumor necrosis factor-α [TNF-α], interleukin [IL]-6, and IL-10) were obtained before the administration of dexmedetomidine or epidural anesthesia (baseline), immediately after tracheal intubation, upon incision, at the time of celiac exploration, and at tracheal extubation. RESULTS: Compared with group E, there were no differences in the plasma concentration levels of NE, E, Cor, and cytokines (TNF-α, IL-6, and IL-10) in group D at all time points. The levels of NE and E in groups D and E were significantly lower than that in group C, at all time points following induction (all P < 0.0001 except at incision which were P = 0.001 and P = 0.004), and the level of Cor in groups D and E was significantly lower than that in group C at celiac exploration (P = 0.017 and P = 0.019) and immediately after tracheal extubation (P < 0.0001). The levels of TNF-α, IL-6, and IL-10 increased after the celiac exploration in the 3 groups. The levels of plasma TNF-α, IL-6, and IL-6/IL-10 ratio were higher in group C than in groups D and E at celiac exploration and tracheal extubation (all P < 0.0001 except at celiac exploration which were P = 0.005 and P =0.038 for TNF-α and P = 0.049 and P = 0.038 for IL-6/IL-10 ratio). In group D, the heart rate was significantly slower after commencing dexmedetomidine and remained significantly slower throughout the operative course (all P < 0.0001 except at tracheal extubation which was P = 0.032). The number of patients who required intervention because of intraoperative hypotension was significantly higher in group E (36.7%) compared with groups D and C (13.3% and 10.0%) (P = 0.037, P = 0.015). The times to eye opening and tracheal extubation were similar in all groups. There were fewer incidences of agitation in group D (6.7 %) than in group C (26.6%) (P = 0.038). CONCLUSIONS: When used in conjunction with TIVA, intraoperative dexmedetomidine blunts surgical stress responses to an extent comparable to combined epidural and general anesthesia without compromising hemodynamic stability and with minimal adverse effects during the intraoperative period.

Components of Patient Satisfaction After Orthognathic Surgery.

The purpose of this study was to compare overall patient satisfaction after orthognathic surgery with the following specific categories: appearance, functional ability, general health, sociability, and patient-clinician communication. A 16-question survey was developed and administered to include patients at either 6 or 12 months after orthognathic surgery between June 2013 and June 2014 at the University of Pennsylvania and Massachusetts General Hospital. The predictor variables included age, sex, type of procedure, medical comorbidities, intra- or postoperative complications, and presence of paresthesia. The outcome variable was patient satisfaction overall and in each category based on a Likert scale (0: not satisfied at all to 5: very satisfied).A total of 37 patients completed the survey and had a high overall rate of satisfaction (100% of responses were 4 or 5 on Likert scale). Overall satisfaction had the highest correlation with appearance (ρ=0.52, P=0.0009) followed by sociability (ρ=0.47, P=0.004), patient-clinician communication (ρ=0.38, P=0.02) functionality (ρ=0.19, P=0.26), and general health (ρ = -0.11, P = 0.51). Patients had high satisfaction scores for orthognathic surgery. Satisfaction with postoperative appearance had the strongest correlation with overall satisfaction.

Perioperative anxiety and postoperative pain in children and adolescents undergoing elective surgical procedures: a quantitative systematic review.

AIMS: To examine the relationship between perioperative anxiety and postoperative pain in children and adolescents undergoing elective surgical procedures and the differences in children's perioperative anxiety and postoperative pain among subgroups of demographics. BACKGROUND: While anxiety and pain are regarded as two common problems experienced by children and adolescents perioperatively and the relationship between them has been reported in previous studies, there has been no review paper examining this phenomenon. DESIGN: A quantitative systematic review. DATA SOURCES: Nine electronic databases were searched for studies published in English from the inception date of the databases to December 2010, using various combinations of search terms of 'adolescents', 'anxiety', 'child', 'pain', 'surgery' and 'correlation/relationship'. REVIEW METHODS: Using the Joanna Briggs Institute's comprehensive systematic review strategies, relevant studies were independently appraised and extracted by two reviewers using the standardized critical appraisal instruments and data extraction tool from Joanna Briggs Institute Meta Analysis of Statistics Assessment and Review Instrument. RESULTS: Ten studies were included in this review from 943 studies initially retrieved. Children and adolescents who had higher level of perioperative anxiety experienced a higher level of postoperative pain. Inconclusive evidence was found regarding differences of perioperative anxiety and postoperative pain between demographic subgroups of gender, age and past surgical experience. CONCLUSION: Results of this review inform healthcare providers of the role perioperative anxiety plays on children's and adolescents' postoperative pain and indicate the need to use interventions to reduce perioperative anxiety and, therefore, optimize their postoperative pain management during the perioperative period.

Surgical complications and their implications for surgeons' well-being.

BACKGROUND: Healthcare professionals can be seriously affected when they are involved in major clinical incidents. The impact of such incidents on staff is of particular relevance to surgery, as the operating room is one of the highest-risk areas for serious complications. This qualitative study aimed to assess the personal and professional impact of surgical complications on surgeons. METHODS: This single time point study involved semistructured, individual interviews with general and vascular surgeons, consultants and senior registrars from two National Health Service organizations in London, UK. RESULTS: Twenty-seven surgeons participated. Many were seriously affected by major surgical complications. Surgeons' practice was also often affected, not always in the best interest of their patients. The surgeons' reactions depended on the preventability of the complications, their personality and experience, patient outcomes and patients' reactions, as well as colleagues' reactions and the culture of the institution. Discussing complications, deconstructing the incidents and rationalizing were the most commonly quoted coping mechanisms. Institutional support was generally described as inadequate, and the participants often reported the existence of strong institutional blame cultures. Suggestions for supporting surgeons in managing the personal impact of complications included better mentoring, teamwork approaches, blame-free opportunities for the discussion of complications, and structures aimed at the human aspects of complications. CONCLUSION: Those involved in the management of surgical services need to consider how to improve support for surgeons in the aftermath of major surgical incidents.

Importance of cosmesis to patients undergoing renal surgery: a comparison of laparoendoscopic single-site (LESS), laparoscopic and open surgery.

UNLABELLED: Study Type - Therapy (case series). Level of Evidence 4. What's known on the subject? and What does the study add? Studies in other surgical populations have found that scarring is a relatively unimportant preoperative patient consideration when compared with surgical cure and safety, but that younger age was a significant factor influencing preference for 'scarless' surgery. The present study corroborates the findings of previous series, among patients who were contemplating kidney surgery. OBJECTIVE: • To evaluate patient attitudes towards cosmesis relative to other considerations, before and after undergoing laparoendoscopic single-site surgery (LESS) vs laparoscopic/robot-assisted vs open kidney surgery. METHODS: • Participants were provided with a survey querying demographic information, surgical history and importance of scarring relative to other surgical outcomes and considerations. • The relative importance of each outcome was recorded on a nine-level ranking scale, ranging from 1 (most important) to 9 (least important). • The median scores for each outcome were compared before and after surgery using the Wilcoxon signed-rank test, and by surgical approach using the Kruskal-Wallis test. • The importance of scarring was further analysed according to age (≤ 50 vs >50 years), surgical indication (oncological vs non-oncological), gender, and proportion of patients who had undergone previous abdominal surgery. RESULTS: • A total of 90 patients completed surveys before surgery, of whom 65 (72.2%) also completed surveys after surgery. • 'Surgeon reputation' and 'no complications' were the most important considerations before surgery (median scores 2 and 3, respectively) and after surgery (median scores of 2 for both). • 'Size/number of scars' was the least important consideration before surgery (median score 8) and the second least important consideration after surgery (median score 7). • The median score for 'size/number of scars' was significantly higher for the LESS cohort before surgery (laparoscopic/robot-assisted vs LESS vs open surgery: 8.5 vs 6 vs 9; P = 0.003), but was nonsignificant after surgery (laparoscopic/robotic vs LESS vs open surgery: 7 vs 6.5 vs 7.5; P = 0.83). • The median score for 'size/number of scars' before surgery was significantly higher for younger patients (P = 0.05) and those with non-oncological surgical indications (P < 0.001), but there was no significant difference in this outcome for these sub-groups after surgery. CONCLUSIONS: • For most patients contemplating urological surgery, cosmesis is of less concern than surgeon reputation and avoidance of surgical complications. • Cosmesis may be a more important preoperative consideration for younger patients and those with benign conditions, which warrants further investigation.

PERCEPTION OF NIGERIAN ANAESTHETISTS ON INTRA-OPERATIVE DEATH.

BACKGROUND: Intra-operative death is an unusual devastating occurrence in anaesthetic practice, and it is of serious concern when it happens. OBJECTIVES: To assess the causes, the effects and the perception of Nigerian anaesthetists to intra-operative death. DESIGN: A cross-sectional and questionnaire-based study. SETTING: Five University Teaching Hospitals in South-Western Nigeria. SUBJECTS: Nurse anaesthetists, resident doctors in anaesthesia and consultant anaesthetists. RESULTS: One hundred and five anaesthetists participated in the study (72.9% response rate). Seventy seven (73.3%) of the respondents had experienced an intra-operative death with most of them having five or more years of experience (p = 0.0001). Majority 53 (68.8%) of the respondents felt that the deaths were avoidable, and most deaths occurred mainly during emergency surgery (96.1%). Forty three (55.8%) of them were psychologically disturbed, fifty six (53.3%) respondents were of the opinion that it is reasonable for the anaesthetists involved not to take partin further surgery for that day. Sixty (57.1%) respondents considered discussion at mortality meeting as appropriate after an intra-operative death. CONCLUSION: This study showed that most anaesthetists would want those involved in the intra-operative death not to take part in further surgery for that day. Adequate preventive measures should be put in place with departmental or institutional policies on what to do after such events.

Stress management training for surgeons-a randomized, controlled, intervention study.

BACKGROUND: Stress and coping influence performance. In this study, we evaluate a novel stress management intervention for surgeons. METHODS: A randomized control group design was used. Sixteen surgeons were allocated to either the intervention or control group. The intervention group received training on coping strategies, mental rehearsal, and relaxation. Performance measures were obtained during simulated operations and included objective-structured assessment of technical skill, observational teamwork assessment for surgery, and end product assessment rated by experts. Stress was assessed using the state-trait-anxiety-inventory, observer rating, coefficient of heart rate variability (C_HRV), and salivary cortisol. The number of applied surgical coping strategies (number of coping strategies [NC]) was assessed using a questionnaire. A t test for paired samples investigated any within-subject changes, and multiple linear regression analysis explored between-subject effects. Interviews explored surgeons' perceptions of the intervention. RESULTS: The intervention group showed enhanced observational teamwork assessment for surgery performance (t = -2.767, P < 0.05), and increased coping skills (t = -4.690, P < 0.01), and reduced stress reflected inheart rate variability (t = -4.008, P < 0.01). No significant changes were identified in the control group. Linear regression analysis confirmed a significant effect on NC (ß = -0.739, P < 0.01). Qualitative data analysis revealed improved technical skills, decision making, and confidence. CONCLUSIONS: The intervention had beneficial effects on coping, stress, and nontechnical skills during simulated surgery.

A qualitative study of women's preferences for treatment of pelvic floor disorders.

OBJECTIVE: to explore women's perceptions of new and established treatments for stress urinary incontinence (SUI) and prolapse, and to identify factors important to women in decision-making about treatments. DESIGN: qualitative interview study. SETTING: urogynaecology unit in a large UK district general hospital. POPULATION: women referred from their general practitioner with SUI and/or prolapse symptoms. METHODS: each woman was given a questionnaire detailing nonsurgical and surgical treatments for SUI and/or prolapse. This briefly detailed the treatment, together with published success and complication rates. Participants were taken through a semi-structured interview based on their perceptions of each treatment, and the factors that lead them to find treatments acceptable or not acceptable. Interviews were conducted by a member of the research team before the initial appointment with the clinical team. Interviews were transcribed and subjected to thematic analysis using constant comparison derived from grounded theory. MAIN OUTCOME MEASURE: themes identified from analysis of interview transcripts. RESULTS: a total of 16 women were interviewed. Their median age was 54 years (range 48-70 years). Women with SUI were keen to have the treatment with the highest chance of long-term success, even if this was more invasive. Women with prolapse were more unsure about this, and less willing to risk potential complications for a higher chance of long-term success. CONCLUSIONS: many factors affect women's decision-making with regards to treatment choices. This analysis highlights the need for careful exploration of women's hopes and expectations before embarking on treatment.

Effects of intraoperative breaks on mental and somatic operator fatigue: a randomized clinical trial.

BACKGROUND: Intermittent work breaks are common in fields with high workload but not yet for surgeons during operations. We evaluated the effects of intraoperative breaks during complex laparoscopic surgery (5 min every half hour) on the surgeon. METHODS: Fifty-one operations were randomized to a scheme with intraoperative breaks and release of the pneumoperitoneum (intermittent pneumoperitoneum (IPP)) or conventional conduct (CPP). Stress hormones and α-amylase were determined in the surgeon's saliva pre-, intra-, and postoperatively. Mental performance and error scores, musculoskeletal strain, and continuous ECG were secondary endpoints. RESULTS: Regular intraoperative breaks did not prolong the operation (IPP vs. CPP group: 176 vs. 180 min, p > 0.05). The surgeon's cortisol levels during the operation were reduced by 22 ± 10.3% in the IPP vs. the CPP group (p < 0.05). There were significantly fewer (p < 0.05) intraoperative events in the IPP vs. the CPP group, which yielded higher α-amylase peaks. The pre- to postoperative increase in the error rates of the bp-concentration test was fourfold reduced in the IPP group (p = 0.052). The relevant locomotive strain-scores were grossly reduced by IPP (p < 0.001). CONCLUSIONS: Our data support the idea that work breaks during complex laparoscopic surgery can reduce psychological stress and preserve performance without prolongation of the operation time compared with the traditional work scheme.

The effects of stress and coping on surgical performance during simulations.

OBJECTIVE: This study investigates the effects of surgeons' stress levels and coping strategies on surgical performance during simulated operations. METHODS: Thirty surgeons carried out each a non-crisis and a crisis scenario of a simulated operation. Surgeons' stress levels were assessed by several measures: self-assessments and observer ratings of stress, heart rate, heart rate variability, and salivary cortisol. Coping strategies were explored qualitatively and quantified to a coping score. Experience in surgery was included as an additional predictor. Outcome measures consisted of technical surgical skills using Objective Structured Assessment of Technical Skill (OSATS), nontechnical surgical skills using Observational Teamwork Assessment for Surgery (OTAS), and the quality of the operative end product using End Product Assessment (EPA). Uni- and multivariate linear regression were used to assess the independent effects of predictor variables on each performance measure. RESULTS: During the non-crisis simulation, a high coping score and experience significantly enhanced EPA (beta1, 0.279; 0.009-0.460; P= 0.04; beta2, 0.571; 4.328-12.669, P< 0.001; respectively). During the crisis simulation, a significant beneficial effect of the interaction of high experience and low stress on all performance measures was found (EPA: beta, 0.537; 2.079-8.543; OSATS: beta, 0.707; 8.708-17.860; OTAS: beta, 0.654; 13.090-30.483; P< 0.01). Coping significantly enhanced nontechnical skills (beta, 0.302; 0.117-1.624, P= 0.03). CONCLUSIONS: Clinicians' stress and coping influenced surgical performance during simulated operations. Hence, these are critical factors for the quality of health care.

A novel classification instrument for intraoperative awareness events.

BACKGROUND: Intraoperative awareness with explicit recall occurs in approximately 1-2 cases per 1000. Given the rarity of the event, a better understanding of awareness and its sequelae will likely require the compilation of data from numerous studies. As such, a standard description and expression of awareness events would be of value. METHODS: We developed a novel classification instrument for intraoperative awareness events: Class 0: no awareness; Class 1: isolated auditory perceptions; Class 2: tactile perceptions (e.g., surgical manipulation or endotracheal tube); Class 3: pain; Class 4: paralysis (e.g., feeling one cannot move, speak, or breathe); and Class 5: paralysis and pain. An additional designation of "D" for distress was also included for patient reports of fear, anxiety, suffocation, sense of doom, sense of impending death, or other explicit descriptions. We reviewed 15 studies of the incidence of awareness that provided specific information about awareness reports. Five anesthesiologists at three institutions who developed the categories independently classified the events. An additional 20 individuals (attending anesthesiologists, anesthesiology residents, nurse anesthetists, medical students, and ancillary staff) not involved in the development of the categories also independently classified the events. Fleiss's kappa statistic was used to evaluate inter-observer agreement. RESULTS: One hundred fifty-one cases of intraoperative awareness in adults were identified as valid for analysis. The overall kappa value was 0.851 (0.847-0.856, 95% confidence interval) for the basic Classes 1-5. Including additional designations of emotional distress, the overall kappa value was 0.779 (0.776-0.783, 95% confidence interval). CONCLUSION: We report a novel classification instrument for intraoperative awareness events that has excellent inter-observer agreement and that may facilitate the study of intraoperative awareness.

[Lipid emulsion therapy for local anaesthetic toxicity. (LipidRescue)]. / Lipidlösungen zur Therapie der Lokalanästhetikaintoxikation. (LipidRescue).

Intoxication due to local anaesthetic drugs poses a rare but potentially life-threatening complication. In particular long-acting local anaesthetics can cause refractory cardiac arrest due to their lipophilic properties. This is often preceded by neurological symptoms such as confusion, vertigo and tonic-clonic seizures. The clinical efficacy of lipid emulsions in resuscitation from local anaesthetic toxicity has been documented in multiple publications. The injection of local anaesthetics should be stopped immediately upon the first presentation of symptoms. Securing the airway is mandatory to avoid hypoxia and concurrent acidosis. A seizure should be controlled with adequate doses of anticonvulsants. In case of cardiac arrest standard protocols for cardiopulmonary resuscitation have to be implemented immediately. The use of lipid emulsion can then be initiated as a supplement to standard resuscitation. It is recommended that lipid emulsions are instantly accessible in all facilities where local anaesthetics are administered.

Design and Impact of a Novel Surgery-Specific Second Victim Peer Support Program.

BACKGROUND: Surgeons are prone to feelings of sadness, guilt, and anxiety when involved in major adverse events. We aimed to create and evaluate a second victim peer support program for surgeons and surgical trainees. STUDY DESIGN: The second victim peer support program was an intervention performed in the Department of Surgery at a tertiary care academic medical center. Surgical attendings and trainees participated as peer supporters or affected peers. In this article, we describe the design of the program and its 1-year impact, which was evaluated through the number of interventions attempted and realized and feedback received from all participants using an anonymous qualitative and quantitative survey. RESULTS: The program was established using the following 5 steps: creation of a conceptual framework, choice of peer supporters, training of peer supporters, multifaceted identification of major adverse events, and design of a systematic intervention plan. In 1 year, the program had 47 interventions distributed evenly between attendings and trainees; 19% of affected peers opted out of receiving support. Most participants expressed satisfaction with the program's confidentiality, the safe/trusting environment it provided, and the timeliness of the intervention (89%, 73%, and 83%, respectively); 81% suggested that the program had a positive impact on the department's "safety and support" culture and would recommend the program to a colleague. Several areas for improvement were identified, including the need to improve identification of events requiring outreach, and the desire for increased awareness of the program throughout the department. CONCLUSIONS: We successfully designed, implemented, and assessed the impact of the first surgery-specific peer support program in the US. Our 1-year experience suggests that the program is highly used and well received, albeit with opportunities for improvement.
