Luo L, Yang L, Lou F, Zhang J. Transcutaneous Pericardium 6 Acupoint Electrical Stimulation Provides Comparable Antiemetic Effect to Granisetron When Combined With Dexamethasone in Patients Undergoing Breast Cancer Surgery. J Surg Res 2024; 303:81-88. [PMID: 39303649 DOI: 10.1016/j.jss.2024.08.016] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/10/2024] [Revised: 07/09/2024] [Accepted: 08/16/2024] [Indexed: 09/22/2024]
Abstract
INTRODUCTION Perioperative transcutaneous pericardium 6 (P6) electrical stimulation is effective for prevention of postoperative nausea and vomiting (PONV). The patients undergoing breast cancer surgery have a high PONV prevalence; however, the effectiveness of P6 stimulation in this surgical population has not been investigated. MATERIALS AND METHODS A total of 198 patients undergoing mastectomy under general anesthesia were enrolled. They were randomly assigned to the one of three treatments: P6 stimulation + dexamethasone (group PD, n = 66), granisetron + dexamethasone (group GD, n = 66), and dexamethasone alone (group DM, n = 66). The primary endpoint was the incidence of postoperative vomiting (POV) within postoperative 48h. The secondary endpoints included the use of rescue antiemetic, severity of POV, and the incidence of postoperative nausea and other adverse events. RESULTS The incidence of POV in group PD (9.1%) was similar to group GD (10.6%, P = 0.770), but significantly lower than that in the group DM (28.8%, P = 0.004) within postoperative 48 h. And, the incidence of postoperative nausea was similar between group PD and group GD but lower than that in group DM. The use of rescue antiemetics had no statistical differences among the three groups. The median (interquartile range) scores of POV severity were higher in group GD [6.0 (5.0, 7.0)] than in group DM [4.0 (3.0, 6.0), P = 0.012] within postoperative 48 h, but similar to group PD [5.5 (4.0, 6.3), P = 0.208]. CONCLUSIONS Combined with dexamethasone, P6 stimulation has similar effectiveness for PONV prophylaxis with 5- hydroxytryptamine 3 antagonist granisetron but lower cost of antiemetic use. Moreover, both groups had a lower incidence of PONV and higher satisfaction than dexamethasone alone in patients undergoing breast cancer surgery.

Arslan HN, Çelik SŞ. Nonpharmacological Nursing Interventions in Postoperative Nausea and Vomiting: A Systematic Review. J Perianesth Nurs 2024; 39:142-154. [PMID: 37865902 DOI: 10.1016/j.jopan.2023.06.096] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/12/2022] [Revised: 06/22/2023] [Accepted: 06/27/2023] [Indexed: 10/23/2023]
Abstract
PURPOSE This study aims to assess the impact of nonpharmacological nursing interventions on postoperative nausea and vomiting (PONV). DESIGN This is a systematic review. METHODS MEDLINE, Web of Science, ScienceDirect, Tübitak-ULAKBİM, and TRDizin databases were searched for the following search terms, including "Postoperative Nausea and Vomiting," "Nurse," "Nursing," and "Nonpharmacological Interventions" to identify nonpharmacological nursing interventions for PONV. A systematic review of English and Turkish articles published in the period between January 1, 2012 and June 1, 2023 was conducted. The PICOT-SD method was used to determine the compatibility of the pieces with the eligibility criteria. FINDINGS Fifty-eight of 3,874 articles obtained from databases fulfilled the eligibility criteria. This study demonstrated that acupuncture, aromatherapy, the oral intake of ginger, listening to music, education, and visits to patients decreased the incidence of nausea and vomiting and increased the quality of life. Additionally, it was found that patients' quality of life tended to improve along with reductions in postoperative complications. CONCLUSIONS The results of this study support previous findings in the literature and demonstrate that nonpharmacological nursing interventions help reduce and prevent PONV. Based on our results, we suggest that nonpharmacological nursing interventions can be employed for the management of PONV in patients undergoing surgery.

Application of veterinary naturopathy and complementary medicine in small animal medicine—A survey among German veterinary practitioners. PLoS One 2022; 17:e0264022. [PMID: 35226679 PMCID: PMC8884514 DOI: 10.1371/journal.pone.0264022] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/21/2021] [Accepted: 02/01/2022] [Indexed: 11/30/2022] Open
Abstract
Background The international use of and interest in veterinary naturopathy and complementary medicine are increasing. There are diverse modes of treatment, and owners seem to be well informed. However, there is a lack of data that describes the state of naturopathic or complementary veterinary medicine in Germany. This study aims to address the issue by mapping the currently used treatment modalities, indications, existing qualifications, and information pathways. In order to map the ongoing controversy, this study records the advantages and disadvantages of these medicines as experienced by veterinarians. Demographic influences are investigated to describe distributional impacts on using veterinary naturopathy and complementary medicine. Methods A standardised questionnaire was used for the cross-sectional survey. It was distributed throughout Germany in a written and digital format from September 2016 to January 2018. Because of the open nature of data collection, the return rate of questionnaires could not be calculated. To establish a feasible timeframe, active data collection stopped when the previously calculated limit of 1061 questionnaires was reached. With the included incoming questionnaires of that day a total of 1087 questionnaires were collected. Completely blank questionnaires and those where participants did not meet the inclusion criteria (were not included, leaving 870 out of 1087 questionnaires to be evaluated. A literature review and the first test run of the questionnaire identified the following treatment modalities: homoeopathy, phytotherapy, traditional Chinese medicine (TCM), biophysical treatments, manual treatments, Bach Flower Remedies, neural therapy, homotoxicology, organotherapy, and hirudotherapy which were included in the questionnaire. Categorical items were processed using descriptive statistics in absolute and relative numbers based on the population of completed answers provided for each item. Multiple choices were possible. Metric data were not normally distributed (Shapiro Wilk Test); hence the median, minimum, and maximum were used for description. The impact of demographic data on the implementation of veterinary naturopathy and complementary techniques was calculated using the Mann-Whitney-U-Test for metric data and the exact Fisher-Test for categorical data. Results Overall 85.4% (n = 679 of total 795 non-blank data sets) of all the questionnaire participants used naturopathy and complementary medicine. The treatments most commonly used were complex homoeopathy (70.4%, n = 478), phytotherapy (60.2%, n = 409), classic homoeopathy (44.3%, n = 301) and biophysical treatments (40.1%, n = 272). The most common indications were orthopedic (n = 1798), geriatric (n = 1428) and metabolic diseases (n = 1124). Over the last five years, owner demand for naturopathy and complementary treatments was rated as growing by 57.9% of respondents (n = 457 of total 789). Veterinarians most commonly used scientific journals and publications as sources for information about naturopathic and complementary contents (60.8%, n = 479 of total 788). These were followed by advanced training acknowledged by the ATF (Academy for Veterinary Continuing Education, an organisation that certifies independent veterinary continuing education in Germany) (48.6%, n = 383). The current information about naturopathy and complementary medicine was rated as adequate or nearly adequate by a plurality (39.5%, n = 308) of the respondents of this question. Further, 27.7% (n = 216) of participants chose the option that they were not confident to answer this question and 91 answers were left blank. The most commonly named advantages in using veterinary naturopathy and complementary medicine were the expansion of treatment modalities (73.5%, n = 566 of total 770), customer satisfaction (70.8%, n = 545) and lower side effects (63.2%, n = 487). The ambiguity of studies, as well as the unclear evidence of mode of action and effectiveness (62.1%, n = 483) and high expectations of owners (50.5%, n = 393) were the disadvantages mentioned most frequently. Classic homoeopathy, in particular, has been named in this context (78.4%, n = 333 of total 425). Age, gender, and type of employment showed a statistically significant impact on the use of naturopathy and complementary medicine by veterinarians (p < 0.001). The university of final graduation showed a weaker but still statistically significant impact (p = 0.027). Users of veterinary naturopathy and complementary medicine tended to be older, female, self-employed and a higher percentage of them completed their studies at the University of Berlin. The working environment (rural or urban space) showed no statistical impact on the veterinary naturopathy or complementary medicine profession. Conclusion This is the first study to provide German data on the actual use of naturopathy and complementary medicine in small animal science. Despite a potential bias due to voluntary participation, it shows a large number of applications for various indications. Homoeopathy was mentioned most frequently as the treatment option with the most potential disadvantages. However, it is also the most frequently used treatment option in this study. The presented study, despite its restrictions, supports the need for a discussion about evidence, official regulations, and the need for acknowledged qualifications because of the widespread application of veterinary naturopathy and complementary medicine. More data regarding the effectiveness and the mode of action is needed to enable veterinarians to provide evidence-based advice to pet owners.

Abstract
PRACTICAL RELEVANCE Increases in cat ownership worldwide mean more cats are requiring veterinary care. Illness, trauma and surgery can result in acute pain, and effective management of pain is required for optimal feline welfare (ie, physical health and mental wellbeing). Validated pain assessment tools are available and pain management plans for the individual patient should incorporate pharmacological and non-pharmacological therapy. Preventive and multimodal analgesia, including local anaesthesia, are important principles of pain management, and the choice of analgesic drugs should take into account the type, severity and duration of pain, presence of comorbidities and avoidance of adverse effects. Nursing care, environmental modifications and cat friendly handling are likewise pivotal to the pain management plan, as is a team approach, involving the cat carer. CLINICAL CHALLENGES Pain has traditionally been under-recognised in cats. Pain assessment tools are not widely implemented, and signs of pain in this species may be subtle. The unique challenges of feline metabolism and comorbidities may lead to undertreatment of pain and the development of peripheral and central sensitisation. Lack of availability or experience with various analgesic drugs may compromise effective pain management. EVIDENCE BASE These Guidelines have been created by a panel of experts and the International Society of Feline Medicine (ISFM) based on the available literature and the authors' experience. They are aimed at general practitioners to assist in the assessment, prevention and management of acute pain in feline patients, and to provide a practical guide to selection and dosing of effective analgesic agents.

Abstract
Naturopathic and complementary procedures attain increasing popularity in veterinary medicine. A common understanding of definitions and contents of these fields is crucial for communication between pet owners and veterinarians. This paper reviews the existing definitions and the various contents of naturopathy and complementary veterinary medicine as well as their assigned treatment options. Naturopathy includes phytotherapy, hydro-therapy, thermotherapy, electrotherapy, manual therapy/chiropractic/osteopathy, and dietetic treatment. Homeopathy, homotoxicology, Traditional Chinese Medicine including acu-puncture and Chinese herbal medicine, neural therapy, organotherapy and Bach flower remedies are known as complementary treatments. The level of evidence based on scientific literature and the opportunity for certification procedures differ between treatment modalities. In the area of small animal medicine, the most extensive body of literature is available on the subject of acupuncture, in part comprising high evidence levels.

Vet Sci 2020; 7:vetsci7030094. [PMID: 32708066 PMCID: PMC7559566 DOI: 10.3390/vetsci7030094] [Citation(s) in RCA: 4] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/28/2020] [Revised: 07/15/2020] [Accepted: 07/17/2020] [Indexed: 11/17/2022] Open
Abstract
Background: This prospective, randomised and blind study investigated the efficacy of laserpuncture for postoperative pain management in dogs. Method: Sixteen bitches were sedated with acepromazine and randomly treated before ovariohysterectomy with meloxicam 0.2 mg·kg−1 intramuscular or laserpuncture (wavelength 904 mm, frequency 124 Hz, potency 10 Joules, 100 s in each acupoint). Anaesthesia was performed with propofol, isoflurane/O2, and fentanyl. The Glasgow Composite Measure Pain Scale (GCMPS) and Dynamic Interactive Visual Analog Scale (DIVAS) were used to evaluate postoperative pain before and for 24 h after surgery. Morphine was administrated as rescue analgesia when pain scores were ≥3.33 (GCMPS). Differences between treatments, time points, and amount of rescue analgesia between groups were investigated by the Mann–Whitney test and the area under the curve (AUC) for GCMPS, Friedman, and Chi-squared tests, respectively (p < 0.05). Results: Dogs treated with laserpuncture presented lower GCMPS AUC for 24 h and lower GCMPS scores at 2 and 4 h postoperatively (p = 0.04). Three dogs treated with meloxicam required postoperatively rescue analgesia against none treated with laserpuncture. Conclusions: In this preliminary study, laserpuncture mitigated postoperative pain in dogs following ovariohysterectomy, and the technique is a promising adjunct to perioperative pain management in dogs undergoing soft tissue surgery.

Abstract
The objectives of this study were to assess gastrointestinal transit times, sedation, and signs of nausea associated with intravenous lidocaine infusions in dogs following targeted acupuncture at Pericardium-6 (PC6) and Stomach-36 (ST36). In a randomized, blind crossover design, 6 healthy, adult Beagles were fed thirty 1.5 mm barium-impregnated polyethylene spheres (BIPS), then were subject to 30 minutes of: 1) no acupuncture, 2) bilateral targeted acupuncture at PC6 and ST36, or 3) bilateral non-target acupuncture at Lung-5 (LU5) and Bladder-55 (BL55). Lidocaine was immediately administered at 1 mg/kg intravenously followed by 50 μg/kg/min. BIPS were tracked radiographically; sedation and nausea were scored at baseline (Time 0) and for 11 hours during lidocaine infusions. Transit times and sedation and nausea scores were analyzed with a linear mixed-effects model; the number of BIPS at defined time points was analyzed with a piecewise linear mixed-effects model. All P values were two-sided and P < 0.05 was considered significant. Sedation and nausea scores did not differ between treatments at any time point (all P > 0.05). However, nausea scores in all groups were significantly greater at Times 5 through 7 and at Time 11 compared to Time 0 whereas sedation scores in all groups were significantly greater at Times 2 through 11 compared to Time 0 (all P < 0.05). The number of BIPs found out of the stomach, the number found in the large intestine, gastric emptying and gastrointestinal transit times did not differ between treatments (all P > 0.05). Acupuncture at PC6 and ST36 did not alleviate nausea and sedation associated with lidocaine infusions in clinically normal animals or affect gastric emptying and gastrointestinal transit.

Abstract
OBJECTIVE To compare the antinociceptive, sedative and cardiovascular effects of dexmedetomidine pharmacopuncture at Governing Vessel 1 (GV 1) with dexmedetomidine intramuscular (IM) administration. STUDY DESIGN Randomized, masked crossover design. ANIMALS A group of eight healthy female cats. METHODS Cats were randomly administered either dexmedetomidine (0.005 mg kg-1; Dex-IM) IM or at acupuncture point GV 1 (Dex-P) separated by 1 week. Prior to and up to 120 minutes posttreatment, skin temperature (ST), thermal threshold (TT), heart rate (HR), respiratory rate (fR), sedation, muscle relaxation and auditory response scores were recorded. Parametric data were analyzed using a two-way repeated measures anova followed by Tukey's test for multiple comparisons. Nonparametric data were analyzed using a Friedman test followed by Dunn's multiple comparisons test, and Wilcoxon signed-rank test with Bonferroni correction for multiple comparisons. Significance was set at p ≤ 0.05. RESULTS There were no differences within or between treatments for ST, fR and auditory response. TT was significantly higher at 30-90 minutes in Dex-P (p ≤ 0.0285) than baseline. TT was significantly higher at 60-90 minutes for Dex-P than for Dex-IM (p ≤ 0.0252). HR was significantly lower at 10-75 minutes in Dex-P (p ≤ 0.0378) and at 5-75 minutes in Dex-IM (p ≤ 0.0132) than baseline. Compared with baseline, sedation scores were higher at 25 minutes (p = 0.0327) and 30 minutes (p = 0.0327), and muscle relaxation scores were higher at 25 minutes (p = 0.0151) and 35 minutes (p = 0.0151) in Dex-P. There were no differences in HR, sedation and muscle relaxation scores between treatments. CONCLUSIONS AND CLINICAL RELEVANCE Dex-P increased thermal antinociception compared with Dex-IM at the same dose of dexmedetomidine in cats. This antinociceptive effect must be evaluated under clinical situations.

Abstract
OBJECTIVE To determine the effect of aquapuncture at acupuncture point Pericardium 6 (PC-6) on the incidence of dexmedetomidine-induced vomiting and nausea in cats. STUDY DESIGN Randomized, prospective, crossover study. ANIMALS A group of 22 cats, 14 females and eight males, aged 1-12 years and weighing 3.8-5.9 kg. METHODS Each cat was administered treatments in random order at ≥1 week intervals. For treatment (DEX-A), cats were administered PC-6 stimulation by aquapuncture (0.25 mL/250 μg vitamin B12 injection subcutaneously at PC-6). After 30 minutes, dexmedetomidine (10 μg kg-1) was administered intramuscularly (IM). For control treatment (DEX), cats were administered only dexmedetomidine (10 μg kg-1) IM. Incidence of vomiting, number of vomiting episodes and time to first vomiting were recorded by an observer unaware of treatment allocation. At 30 minutes after dexmedetomidine administration, atipamezole (0.1 mg kg-1) was injected IM. Behavior was video recorded and later scored by two observers for clinical signs of nausea. A regression model (analysis of covariance) was used to detect the influence of aquapuncture on vomiting and nausea. Significance was set at p < 0.05. RESULTS Of 21 cats, 18 (85%) and 16 cats (76%) vomited in DEX-A and DEX, respectively. There was no significant difference in the incidence of vomiting (p = 0.55), number of vomiting episodes (p = 0.55), mean time to vomit (p = 0.88) or nausea score (p = 0.51) between DEX-A and DEX. CONCLUSIONS AND CLINICAL RELEVANCE PC-6 aquapuncture did not reduce the incidence of dexmedetomidine-induced vomiting or severity of nausea in cats.

Abstract
OBJECTIVES To quantify changes in gastric and intestinal emptying times in the conscious dog following gastrointestinal acupoint stimulation. MATERIALS AND METHODS In a randomised, blinded crossover study, six dogs were fed 30×1.5 mm barium-impregnated polyethylene spheres and underwent: (1) no acupuncture (Control); (2) stimulation of target points PC6 and ST36 (Target) and (3) stimulation of non-target points LU7 and BL55 (Sham). Abdominal radiographs were assessed immediately after feeding the spheres and every hour for 12 hours and their number in the stomach and large intestines was counted. RESULTS The number of barium-impregnated polyethylene spheres found distal to the stomach was less in the Target group compared to the Control and Sham groups between hours 2 and 4, but no differences between groups were seen for the remainder of the treatment period. The number of spheres found within the colon/rectum was less in the Target group compared to the Control and Sham groups between hours 4 and 6, and compared to the Sham group only at hour 7 but no differences between groups were seen after hour 8. CLINICAL SIGNIFICANCE Acupuncture targeted at the gastrointestinal tract of dogs was associated briefly with slowed gastric emptying and gastrointestinal transit time. This foundational study lays the groundwork for additional studies of acupuncture effects associated with altered physiologic states.

Abstract
Acupuncture has been practiced for thousands of years, although it is only in the past century that science has worked to unravel the mechanisms behind its use. Literature supporting the efficacious use of acupuncture to treat a variety of conditions has been and continues to be published, including the randomized controlled studies we all appreciate when practicing evidence-based medicine. The use of acupuncture in veterinary medicine has paralleled the trends observed in people, with an increasingly common use to remedy specific medical conditions. These conditions are commonly related to neurological dysfunction or orthopedic pain. Although pain relief is the most common use of acupuncture, numerous other conditions have been shown to improve with this therapy. Laboratory animals are also benefiting from acupuncture. Its use is starting to be incorporated into research settings, although there is still further progress to be made in this field. Acupuncture has been shown to improve clinical conditions and quality of life in laboratory animals, and should be considered as a tool to treat laboratory animals with conditions known to benefit from therapy. Here we review the history, mechanisms of action, and use of acupuncture to treat veterinary patients and laboratory animals.

Yamamoto K, Tatsutani S, Ishida T. Detection of Nausea-Like Response in Rats by Monitoring Facial Expression. Front Pharmacol 2017; 7:534. [PMID: 28119609 PMCID: PMC5222820 DOI: 10.3389/fphar.2016.00534] [Citation(s) in RCA: 9] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/11/2016] [Accepted: 12/23/2016] [Indexed: 12/16/2022] Open
Abstract
Patients receiving cancer chemotherapy experience nausea and vomiting. They are not life-threatening symptoms, but their insufficient control reduces the patients’ quality of life. To identify methods for the management of nausea and vomiting in preclinical studies, the objective evaluation of these symptoms in laboratory animals is required. Unlike vomiting, nausea is defined as a subjective feeling described as recognition of the need to vomit; thus, determination of the severity of nausea in laboratory animals is considered to be difficult. However, since we observed that rats grimace after the administration of cisplatin, we hypothesized that changes in facial expression can be used as a method to detect nausea. In this study, we monitored the changes in the facial expression of rats after the administration of cisplatin and investigated the effect of anti-emetic drugs on the prevention of cisplatin-induced changes in facial expression. Rats were housed in individual cages with free access to food and tap water, and their facial expressions were continuously recorded by infrared video camera. On the day of the experiment, rats received cisplatin (0, 3, and 6 mg/kg, i.p.) with or without a daily injection of a 5-HT3 receptor antagonist (granisetron: 0.1 mg/kg, i.p.) or a neurokinin NK1 receptor antagonist (fosaprepitant: 2 mg/kg, i.p.), and their eye-opening index (the ratio between longitudinal and axial lengths of the eye) in the recorded video image was calculated. Cisplatin significantly and dose-dependently induced a decrease of the eye-opening index 6 h after the cisplatin injection, and the decrease continued for 2 days. The acute phase (day 1), but not the delayed phase (day 2), of the decreased eye-opening index was inhibited by treatment with granisetron; however, fosaprepitant abolished both phases of changes. The time-course of changes in facial expression are similar to clinical evidence of cisplatin-induced nausea in humans. These findings indicate that the monitoring of facial expression has the potential to be useful for the detection of a nausea-like response in laboratory animals.
