OSAS surgery and postoperative discomfort: phase I surgery versus phase II surgery

The Incidence of Obstructive Sleep Apnea in Patients with Dento-Skeletal Malformation

Purpose: The aim of this article is to analyze the incidence of undiagnosed obstructive sleep apnea (OSA) in patients affected by dento-skeletal malformation. We also evaluated the patterns most affected by the condition and calculated the post surgical changes. Methods: We conducted a retrospective cohort study on 71 patients including 35 men and 36 women. The patients studied were affected by dento-skeletal class II and III malformations and underwent bimaxillary orthognathic surgery in all cases. Patients were evaluated with polysomnography before surgery and at least 6 months after surgery to assess any improvement or worsening of the apnea hypopnea index (AHI) index. Regarding AHI evaluation criteria, an AHI > 5 was considered indicative of OSA, 4 < AHI < 5 was considered borderline and AHI < 4 was considered indicative of non-OSA. We also considered demographic variables like age at the time of intervention and gender, and anatomical variables like the pattern of the dento-skeletal deformity and the presence or absence of maxillary hypoplasia. Qualitative variables were described as absolute and relative frequencies, while quantitative variables were summarized as mean and standard deviation. To quantitatively express the relationship between two variables, the correlation coefficient was calculated. The covariance array was used to evaluate multiple correlations. Results: Our study shows that there is a significant percentage (33%) of patients who undergo orthognathic surgery with an AHI > 5 and also a percentage of patients (11%) who can be considered to be "borderline." It emerges that the pattern most at risk is the one characterized by retruded maxilla and patients with dento-skeletal class II. Considering the post surgical period, the statistical analysis shows that after surgery, only 8% of malformed patients present an AHI > 5, compared to the 20.5% described in the Italian population. Conclusions: In patients who receive orthognathic surgery, the presence of obstructive sleep apnea is significantly higher than in the general population. When planning the surgical correction of a dento-skeletal malformation, the surgeon must aim not only for the esthetics results, but also for proper stomatognathic and respiratory function; this cannot be achieved without taking polysomnography information into account.

Postoperative Discomfort Among Laparotomy Patients from a Selected Hospital at Mangaluru: An Observational Study

Background Factors causing postoperative discomfort after laparotomy are numerous and must be explored in depth. The postoperative distress may significantly affect the patient's state of well-being. Hence, the present study aims to assess the factors contributing to discomfort after laparotomy.

Aim The aim was to assess and compare the discomfort between open and laparoscopic abdominal surgery.

Objectives of the Study

1. To analyze the causes of patient's discomfort after abdominal surgery.

2. To compare the discomfort between open and laparoscopic abdominal surgery.

3. To determine the association between pain and selected variables among open and laparoscopic abdominal surgery.

Materials and Methods An exploratory approach with a prospective observational design was adopted for this study. Using the purposive sampling technique, 100 patients were selected to open and 100 to laparoscopic abdominal surgery groups. Data were collected using demographic and clinical proforma and standardized postoperative discomfort inventory 6 and 24 hours after the surgery. The assessment focused on the study variables such as symptoms after the surgery and the factors contributing to the postoperative discomfort.

Statistical Analysis The collected data were analyzed using descriptive and inferential statistics using the SPSS software version 20.

Results Among 200 participants, most of the open (68%) and laparoscopic abdominal surgeries (42%) belong to 25 to 35 years of age. Also, 54% and 13% were diabetic in open and laparoscopic abdominal surgery groups, respectively. Most samples (56% in open and 68% in laparoscopic surgery) stayed 5 and 10 hours in postoperative ICU. In open and laparoscopic abdominal surgeries, pain is the primary (100%) cause of postoperative discomfort after 6 hours of surgery. Movement restriction is also the reason for significant discomfort both in open (98%) and laparoscopic (100%) abdominal surgeries.

In contrast, pain (99% and 100%), movement restriction (92% and 95%), and abdominal distention (61% and 34%) were the major problems contributing to the patient's discomfort after 24 hours of both open and laparoscopic surgeries too. There was a significant difference in causes of patient discomfort between open and laparoscopic abdominal surgery after 6 hours (P < 0.05), except for discomfort related to IV drip (P = 0.852), constipation (P = 0.2), and chills (P = 0.6).

Conclusion Even though pain is the major distressing factor both in open and laparoscopic surgeries, the current study highlights a few other factors that affect postoperative recovery. Nurses' attention to such distressing factors will fasten patients' recovery and quality of life after abdominal surgery.

The Effect of Educational Intervention on the Improvement of Nontechnical Skills in Circulating Nurses

Background

Nontechnical skills are necessary for clinicians' safe performance and prevention of errors in the operating room. Educational intervention is a useful way to improve these skills, which are a vital area for improvement. Circulating nurses are surgical team members whose work depends heavily on using nontechnical skills. This study is aimed at assessing the effect of an educational intervention on the improvement of circulating nurses' nontechnical skills.

Methods

This semiexperimental study was conducted on 300 circulating nurses divided into the intervention and no intervention groups each containing 150 participants. The nontechnical skills were assessed using the circulating practitioners' list of nontechnical skills. Then, the intervention group received training regarding these skills, and the two groups were evaluated again. After all, the data were entered into the SPSS 24 software and were analyzed using descriptive statistics and Wilcoxon and Mann–Whitney tests. Furthermore, Kendall's tau, independent sample t-test, and one-way ANOVA were used for assessment of relationship between median scores and demographics.

Results

The results revealed a significant improvement in the scores of all domains of nontechnical skills in the intervention group (p < 0.05). The highest and lowest improvements were observed in teamwork (42%) and situational awareness (16.7%), respectively. After the intervention, the scores of some of the behaviors were still below the average level or were not improved significantly.

Conclusions

Circulating nurses' nontechnical skills can be improved by educational interventions. However, regarding the low scores or no improvements in the scores of some behaviors, other intervention types such as policymaking and correcting the existing hierarchies in the operating room can be useful to complete the educational interventions.

Health Care Professionals' Assessment of Patient Discomfort After Abdominal Surgery

PURPOSE

The purpose of this study was to classify elements of patients' discomfort in the resuscitation room after open or laparoscopic abdominal surgery as per health care professionals' perceptions.

DESIGN

A prospective cross-sectional study at a tertiary hospital in Spain.

METHODS

Resuscitation room nurses administered the Postoperative Discomfort Inventory to physicians and nurses with >1 year experience working closely with patients who had undergone abdominal surgery, asking them to score nine items related to patients' discomfort in the first 8 hours after surgery on an 11-point scale (0 = absent to 10 = very severe). Interobserver agreement among proxy reporters was measured with the Spearman's ρ; correlations >0.35 was considered adequate agreement.

FINDINGS

Of 125 eligible professionals, 116 (93%) participated (63 [54%] nurses and 53 [46%] physicians; mean age, 38 ± 12 years; 86 [74%] women). Professionals' perception of discomfort differed significantly between patients undergoing open surgery and those undergoing laparoscopic surgery; after open surgery, the most common types were pain (7.1 ± 1.8), movement restriction (7 ± 1.75), and dry mouth (6.6 ± 2.6), whereas after laparoscopic surgery, the most common types were dry mouth (5.85 ± 2.8), abdominal bloating (5.3 ± 2.5), and pain (5 ± 2.2). The Spearman's ρ correlations were inadequate for all items except for dry mouth in open surgery (r = 0.40).

CONCLUSIONS

Pain, movement restriction, abdominal bloating, and dry mouth were the main causes of discomfort. Our findings highlight the need to be vigilant for all manifestations of discomfort after abdominal surgery to enable timely treatment.

Evaluation of the Nasopharyngeal Cannula Use After Orthognathic Surgery: Permeability of the Nasal Airways and Discomfort of the Patient With Cleft Lip and Palate

It is believed that the use of the nasopharyngeal cannula can maintain the patent upper airway in the immediate post-operative period of orthognathic surgery. The present study is a randomized clinical trial with the objective of evaluating the difference in the use of the nasopharyngeal cannula in the post-operative period of orthognathic surgery with respect to permeability and discomfort. The sample was composed of 26 individuals with repaired cleft lip and palate randomly distributed in 2 groups with and without nasopharyngeal cannula. The evaluation was composed by Visual Analogue Scale (VAS), test with Altman mirror in 4 pre-operative periods, 6, 24, 30 hours after the operation. Rhinomanometry was also performed, a flow- pressure technique in 2 distinct moments, 6 and 24 hours after surgery. As a result, greater discomfort, greater obstruction as well as a reduction in the area of bilateral minimum nasal cross-section (ASTM) and increased resistance in the group with nasopharyngeal cannula are observed. In the intra-group comparison with the lowest ASTM values, the test group showed a significant difference between the first and the second moments (P = 0.001). It can be concluded that the nasopharyngeal cannula contributes to increase discomfort, worsens airway permeability by decreasing ASTM and increasing nasal resistance. Regarding the length of stay of the nasopharyngeal cannula, it can be said that from 6 hours onwards it does not contribute to the reduction of discomfort, airway permeability and assist in hemostasis.

Assessment and Management of Postoperative Pain Associated with Sleep Apnea Surgery

A literature review was conducted regarding the assessment and treatment of postoperative pain following surgery for obstructive sleep apnea (OSA). Given the risks of opioid use by patients with OSA, special attention to opioid risk reduction and avoidance is warranted in this population. The results of this review demonstrate the existence of a body of evidence that supports the use of nonopioid analgesics and nonpharmacologic approaches pain management. Strategies for managing postoperative pain should emphasize the use of local anesthetic infiltration, nonsteroidal antiinflammatory drugs, acetaminophen, topical analgesics, surgical wound cooling, and when necessary, safer opioid medications, such as tramadol and intranasal butorphanol.
