| Abstract | Objectives: This study primarily aimed to find a relationship between the length of stay until discharge in the post-anesthetic care unit and the BMI of patients, as well as the first postsurgical pain level they expressed after various forms of surgery. Furthermore, we sought to compare these outcome values with various demographic and perioperative data.
Materials and methods: A retrospective cross-sectional study design was applied, analyzing the anesthesia record sheets of 283 patients who underwent anesthesia within the scope of their surgery and had a subsequent stay in PACU in a time period from November 2021 to March 2022 in the REGIOMED Hospital Coburg, Germany. As these record sheets were without personal information, the resulting dataset remained anonymous. The randomly drawn sample was stratified into meaningful layers with regard to several clinical features. The data collected was analyzed with JASP (JASP Team (2022). JASP (Version0.16.3) [Computer software], Amsterdam, Netherlands) and non-parametric Mann-Whitney-U tests, Kruskal-Wallis tests (including post hoc Dunn tests), as well as Kendall’s Tau-b (τb) and Spearman’s Rho (ρ) correlation tests were applied.
Results: The mean age of the sample was 59.6 ±17.6 years, ranging from 18 to 91 years. The mean BMI was 28.9 ±6.1 kg/m2, the mean NRS was 3.4 ±2.8, and the mean LOS was 114.0 ±50.7 minutes. The majority of the sample was female (57.6%), had a Class II ASA score (39.9%), had no prior history of chronic pain (90.1%), underwent balanced anesthesia (88%), and orthopaedic surgery (34.3%). We found a significant positive correlation between PACU LOS and postsurgical NRS patients expressed in the PACU (Spearman’s ρ; rs (257) = 0.3, p=<.001). We discovered a significant difference in median LOS across the four severity groups after categorizing the NRS into VRS labels and applying a Kruskal-Wallis H test (H(3) 20.695 = p <.001, η2 = 0.08). There was a significant difference in median LOS comparing ASA I through III (H(2) = 7.253, p = 0.021, η2 = 0.026). We discovered a positive correlation tendency among all of the five surgical specialties investigated, two of which were significant (p=0.007, p=0.012). BMI and PACU LOS did not significantly correlate throughout the entire sample (ρ; rs (275) = 0.03, p=0.642) or when subdivided into any of the subgroups.
Conclusion: This study confirmed that a significant positive correlation between the postsurgical pain level and the length of stay in the recovery room exists. In addition, we draw the conclusion that BMI values—high or low—have no influence on LOS. |
| Abstract (croatian) | Ciljevi: Ovo je istraživanje primarno imalo za cilj pronaći odnos između duljine boravka do otpusta u postanestezijskoj jedinici i BMI bolesnika, kao i prve postoperativne razine boli koju su iskazivali nakon različitih oblika kirurškog zahvata. Nadalje, nastojali smo usporediti ove vrijednosti ishoda s različitim demografskim i perioperativnim podacima.
Materijali i metode: Primijenjen je retrospektivni dizajn presječne studije, analizirajući anestezijske listove 283 pacijenta koji su bili podvrgnuti anesteziji u okviru svoje operacije i kasnije su boravili u PACU u vremenskom razdoblju od studenog 2021. do ožujka 2022. u bolnici REGIOMED Coburg, Njemačka. Kako su ti zapisnici bili bez osobnih podataka, rezultirajući skup podataka ostao je anoniman. Nasumično izvučeni uzorak stratificiran je u značajne slojeve s obzirom na nekoliko kliničkih značajki. Prikupljeni podaci analizirani su JASP-om (JASP Team (2022). JASP (Version0.16.3) [Računalni softver], Amsterdam, Nizozemska) i neparametrijskim Mann-Whitney-U testovima, Kruskal-Wallisovim testovima (uključujući post hoc Dunnove testove ), kao i primijenjeni Kendallov Tau-b (τb) i Spearmanov Rho (ρ) korelacijski test.
Rezultati: Prosječna dob uzorka bila je 59,6 ±17,6 godina, u rasponu od 18 do 91 godine. Srednji BMI iznosio je 28,9 ±6,1 kg/m2, srednji NRS 3,4 ±2,8, a srednji LOS 114,0 ±50,7 minuta. Većina uzorka bile su žene (57,6%), imale su rezultat klase II ASA (39,9%), nisu imale prethodnu povijest kronične boli (90,1%), podvrgnute su uravnoteženoj anesteziji (88%) i ortopedskoj operaciji (34,3%) . Pronašli smo značajnu pozitivnu korelaciju između PACU LOS i postkirurških NRS pacijenata izraženih u PACU (Spearmanov ρ; rs (257) = 0,3, p=<,001). Otkrili smo značajnu razliku u medijanu LOS-a u četiri skupine ozbiljnosti nakon kategorizacije NRS-a u VRS oznake i primjene Kruskal-Wallis H testa (H(3) 20,695 = p <0,001, η2 = 0,08). Postojala je značajna razlika u medijanu LOS-a uspoređujući ASA I do III (H(2) = 7,253, p = 0,021, η2 = 0,026). Otkrili smo pozitivnu tendenciju korelacije između svih pet istraživanih kirurških specijalnosti, od kojih su dvije bile značajne (p=0,007, p=0,012). BMI i PACU LOS nisu značajno korelirali u cijelom uzorku (ρ; rs (275) = 0,03, p=0,642) ili kada su podijeljeni u bilo koju od podskupina.
Zaključak: Ovo je istraživanje potvrdilo da postoji značajna pozitivna korelacija između razine postoperativne boli i duljine boravka u sobi za oporavak. Osim toga, zaključujemo da vrijednosti BMI-visoke ili niske-nemaju utjecaja na LOS. |
